Unseizing a seized outboard motor

[@floridamansgarage8629]

I picked up a 9.9 johnson from the 50s! found it on the side of the road seized up and with your method, I brought it back to life I couldn't believe it thanks!

[@DangarMarine]

That is awesome!

[@derekharper7868]

Just found a free yamaha 9.9 on the side of the road myself! Hope I get lucky with it.

[@BigRiverLabrador]

@@derekharper7868how did you make out with your Yamaha 9.9? I just got one myself I’m trying to unseize it’s an 89 or 90 2-stroke

[@derekharper7868]

@@BigRiverLabrador Not sure yet. Don't know the year on mine but it's a 4 stroke. I do know it wasn't siezed. It just had a cylinder full of oil, so it's now moving well but I haven't had a chance to attempt to fire it up.

[@Martinmerton]

@@DangarMarine - quick question. Your video has been super helpful. I have a seized 18HP Tohatsu. I’ve removed the flywheel and there is a nut holding the starter in place. I can unscrew the nut but if I’m trying to rock it should I be tightening it as much as I can clockwise to try to get it to turn? Is there a threat of over tightening the nut? Or should I just keep trying? Thanks for your help.

[@peteryeung111]

You seem like a very honest and hard working guy...good job! Thanks for the video.

Thanks Peter, you're welcome. :)

Nice pic Bruce. You know what his fav drink was??? Waaaaterrrrrr. Take what is useful and disregard the rest🥊

[@scottmckenna9164]

Your a good teacher. Easy to follow, clear, to the point. Thank you for increasing my knowledge of outboards.

[@DangarMarine]

Thanks Scott, glad you like the vids.

[@mpccenturion]

Your vids are always inexpensive ways to fix neglected or minor abuse issues. Lawnmowers and chainsaws were my into to the fixing world. Never did it for a living, but always enjoyed the adventure of figuring out what happened. Cheers

[@DangarMarine]

Thanks mate, it is fun getting to the bottom of faults with motors. :)

[@TitanFallDeath666420]

Just want to say you have saved me hundreds of dollars with your videos to be able to do this stuff my self instead of paying a Marine shop is awesome stuff! Ty Dangar Rebuilt my carb's and new seals in lower unit thank's to you buddy!

[@DangarMarine]

You're welcome mate, glad to help. :)

[@sambreadman8530]

It worked! I seized up a 35 merc. Used PB Blaster and Marvel Mystery Oil as I figured I needed every advantage possible. Let it sit 3 days then very gentle back and forth with the breaker bar and it broke free. More oil in it for another 24 hrs, few more spins then set it up to start. Shocked when it fired up. Great video! thanks so much.

[@DangarMarine]

Glad to hear you got it running again Sam. :)

[@navigator902]

Excellent ... kept me at the edge of my seat.... outboards are just that way... go in for one problem and end up fixing another... Thanks Stew.

[@DangarMarine]

There's no shortage of problems when outboards are involved!

[@dennispfeifer7788]

I purchased a 5 HP 2002 Yamaha for $50...yesterday...it was seized...never worked on outboards in my life..found water in the fuel tank...took short breaker bar and kept working it like you described without much pressure, kinda snapping it lightly, shocking it, and in 10 minutes had it un-siezed and had piston turning smoothly with spray solvent...your video solved the problem...! Thank you so much...Carb is missing so I'll need to source one...Motor looks to be fairly simple to work on since one cylinder and 2 stroke. Now I can check for spark, and compression...I've worked on lots of 2 stroke chain saws and motorcycles...this is kinda fun!

[@paulpvhl1930]

Thanks for this. Just bought a 1966 6HP Johnson that is seized, though it was supposed to be a busted up starter pinion gear that I bought unexamined for $100. Never used or worked on a 2 stroke before, so your videos have been very helpful.

[@DangarMarine]

You're welcome Paul, glad the videos have been helping you.

Thanks Dangar i have a 20 hp 2 stroke Yamaha and im learning so much from you.

You're welcome Benny. :)

[@arthuray6049]

Danger I have a 25 hp mercury outboard that has a compression of 85-90 each cylinder what can I do to increase that ? Thank you great videos !!

[@marksmith9194]

I have a chance to buy a 1970s Johnson 9.5 hp outboard that is frozen for $40. After watching your video, I thought to myself "What do I have to lose?" Thanks for taking the time to explain everything.

[@DangarMarine]

+Mark Smith Good luck with it mate. At the absolutely worst you will learn a lot about outboards as you try to get it running. Go for it! :)

[@alextornello4755]

Just getting started on this video and loved the comment about never working on a boat without coffee.

[@wonjkimchi9891]

i dont have a seized motor but this video made me want to get my hands on one to try it out myself. still a great video in 2024

[@Drbones110]

I'm getting ready to fix my 90's model boat and evinrude 115 thats been sitting for 15 years.I have watched almost every video you made,and that gave me the confidence to do it. I'm sure i will be asking some questions later on, and film a bit you can use on your show, for the what not to do sections.If it works i'll send you some beers.

[@randyvanthoff7761]

My son bought a johnson 35 hp that had been seized since 2008. We followed your video step by step and it worked like a charm! Awesome!

[@walter2990]

I love your videos and have learned a ton from them! There's always another way to do anything, and sometimes another way is better! I once had a motor go under, while tied up to the beach. the transom was facing the small waves all night long, and the bilge pump failed. The small amount of spray from the waves hitting the back of the transom accumulated in the boat during the night (while I was busy drinking far too much beer), and the hull filled up with enough water to sink. So, about 10am the next morning, hung over and still sleeping, one of my drinking buddies from the night before, stopped by my camp and woke me up asking, "Hey, why is your boat under water?" I hoped that he was kidding, but he wasn't. (There's a lot more funny details that go along with this story, but I'll skip to the reason I'm writing this in the first place.) When I was finally able to get the boat back onto the trailer, I took out all of the spark plugs, the air box from the carbs, and just shoved as much fresh water through the engine, that I could from the hose. Spent about 45 minutes douching out the entire engine. The starter actually still worked and so I sprayed 4 cans of WD-40 into the cylinders and the carbs, while cranking the motor and running down 2 car batteries in the process..., and created my own Haz-Mat scene! (Helpful Hint: Don't try to remove a full sized battery from a boat, STILL submerged in salt water..., it really tingles!) It was a week later that I was able to start tearing down the engine, and found ZERO corrosion! Moral of the story..., if you can't do anything else to a motor which has submerged, except flush it out with fresh water..., DO IT! And don't worry about getting anything wet, cause that's already happened! God bless the man who created WD-40! YanceyMan, west central coast of Florida

[@DangarMarine]

Agree completely about flushing with fresh. You can also soak the starter in ethanol to draw the water out of the winding. The other thing I would normally recommend is getting it running as soon as you can after it has been lifted.

[@daveroberts6884]

WD-40 in my experience is both water soluble and oil soluble. It looks like it took care of the water. I think I will keep a big can on my boat. PS: You can remove oil stains from clothes with it, just spray and put in the laundry. It washes out and leaves nothing behind.

[@lyndonbushnell8080]

My Suzuki DT40 looked like it seized up when on the water today & when i got it home i took the pull starter off & it was the issue after all, Thank you for your great video as you saved me some cash getting it looked at.

[@DangarMarine]

You're welcome mate. :)

[@iantyler4045]

Watching your videos during lockdown has kept me sane and I've learned so much. Very well done.

[@DangarMarine]

Great to hear!

[@thomastirolflorida5363]

My Suzuki DF 150 seized at slow speed due to having water and black, thick sludge in lower unit. Got towed and loaded on trailer and drove home. i had to drill out ( bolt extractor) drain plugs of lower unit, flushed with ATF. Installed new drain plugs and gaskets, refilled with gear lube. Ran on Muffs and hose, drained again and filled again.Also changed spark plugs, engine oil and filter, greased up drive shaft, new impeller kit. Motor runs perfect ever since. Wondering how that is possible, not having any damage. BTw , you are brilliant man, very informative and entertaining.

[@mqiqkqer5750]

Very helpful, my boat sank as she was moored up wrong.. she was sat under water for about 4 hours every tide for 2 months before I was able to remove the engine, got he in pices now wish i had seen this before compleatly stripping her down to just the power head. Gives me hope she will live again with out the hassle of sending her off. Thanks from the UK.

[@DangarMarine]

Hi mate, you would probably have found that it needed to be pulled apart anyway if it had been dunked and then exposed to air every tide as that is about the worst case scenario for an outboard. Fingers crossed it will come good though!

[@elspaniard002]

Another wonderful video in which I can hone my skills in the world of outboard mechanics/repairs. Thanks Dangar!

[@jacobthompson9776]

@@southjerseysound7340 Well for one I wish I had watched the video a little longer and just used 2 stroke oil. Anyway it actually worked much easier than expected. Poured in the ATF then acetone. Maybe 30 minutes later and I could spin the fly wheel by hand. Motor started great. Only problem is now there is a problem with the lower unit. Bought a new motor and will try to fix the first one to sell. Break Out Another Thousand

[@jarodmorris611]

I love being on the water. After watching your videos I want to go buy a bunch of old, non-running engines and do the miracles you show on video. If only it were actually that easy. :) Wonderful videos. Hope you keep making them.

Thanks Jarod. The great thing is you can always find an old outboard motor out there somewhere that someone is willing to part with quite cheaply.

[@bartjanflikkema9054]

Just got a 2009 tohatsu 4hp. Got it for 80 euro's. Previous owner lost it from the boat while doing quite a high speed and thus rpm. Hydrolocked totally of course uf to a point that the flywheel key snapped and messed up the timing. Not running of course, and I basically got itas a spare parts engine as optically it was basically new. But curious as I was I Fixed the timing and flushed the oil etc. And now it is running quite fine again. Has a little knock compared to a good good one but less of a noise that the average 2 stroke has. Fun to figure out what happened.

[@christopherrobinson4142]

i really liked the way you summed everything up. instead of using boat college terms lol. this has happened to a motor that i picked up from Indiana and brought it to my home in Colorado; It's a very high humidity place in Indiana and very hot and dry here in Colorado. so second time in the water here and the motor seized. so thank you very much for showing me i can do it myself.

[@DangarMarine]

Thanks Christopher. Good luck with getting the motor going again. :)

[@thilltony3362]

Very nice video. One tip you may like, is to add about 25% acetone to your tranny fluid when using it as a penetrating oil. I learned this from a machine shop, and it really makes a big difference in how well and how quickly it releases frozen parts. Good job on bringing that motor back!

[@DangarMarine]

Thanks Tony, a couple of others commented about adding acetone to the ATF, it certainly sounds like the way to go.

[@su5119]

Good techniques. I inherited two vintage outboards when dad passed. A 1957 7 1/2 hp Johnson and a 1980 Johnson 10 hp. Both bought new. They have not fun for over ten years. It will be fun to get them running and use them on my dink. I liveaboard on an Ericson 35 and always in need of a tender that can run me into shore when anchoring out. Thanks for your site.

[@RichardDePas]

Thanks! Helped me get my Nissan 2 stroke freed up. Fortunately it wasn't nearly as bad as the one in your video. I used 2 stroke oil instead of ATF. Worked like a champ and started on the 4th pull after new plugs and lower unit oil.

[@DangarMarine]

Always good when they come back to life. :)

[@borisleonardoomanasuarez8066]

Do you need to take that oil out before starting it? Will it cause any problems if you start it with that oil inside? Or will it be fine?

[@RichardDePas]

@@borisleonardoomanasuarez8066 make sure you can turn turn it over normally with the plugs in (not hydro-locked with too much oil in the cylinders). If you can, then you can start it. It'll smoke for a bit while it burns off the oil, but it will be fine.

[@shoominati23]

ATF fluid is good to remove contaminants and also protects from corrosion. We use it on my mate's race engine liberally on a towel to scrubs away the carbon ridge at the top of the cylinder so we can remove the pistons without terminally damaging them. Not alot of people give thought to this process. But the stuff is great for any clean up work during a rebuild to remove deposits and inpurities. You can leave it right there when you reassemble the engine, it's not going to hurt anything. I think you could also benefit to use it to get the build up off of things like hydraulic rams, stubborn shafts inside your engine when you want to pull the gearbox and as an all round corrosion inhibitor that doesn't wash off in a minute like WD40, Just as a good going over with a decent amount with a rag on all exposed steel surfaces every time you bring the boat back in. Just a suggestion, I'm not trying to control you or anything man.. A friend said his old man used to work onb Cadillacs in the 60s and many cars would come in with noisy lifters (as they sat more than they drove and the maintenance wasn't always kept up to spec. Anyway, his solution was to dump out a few litres of oil and replace it with ATF and leave the car running outside for a couple of hours, he then dumped the oil and replaced it with fresh stuff and he reckons they were quiet as a mouse after that. Food for thought. I've unseized engines by putting a mixture of ATF and WD40 down the bores and leaving it for a day or two and then trying to see if I can turn it over by hand and rock it back and forth past the point of resistance and slowly keept repeating until it feels normal again. i havent been let down by this.

[@DangarMarine]

ATF certainly is handy stuff for many jobs. It's interesting to hear about it being used to fix the noisy lifters.

Try 50/50 mix of ATF and acetone. It's commonly used for seized pistons on old engines that haven't been cranked for 30-40 years. Fill the cylinders and let them set in the hot sun for a few days. Shouldn't take nearly as long for outboards.

Thanks for sharing this information. Just got a Yamaha 30 going by doing just this. Luckily I only had to let it soak a few hours but man it was stuck good. Funny thing is, is it was not running for years until last summer when I got it going and it started no troubles what so ever, but then after sitting for 12 months it had all seized up

[@DavAnge2022]

Best. Comment. Ever @4:10, this is my motto also-cheers!. Have the F100 torn down as far as I need to as the sump oil was milky. Found the head gasket was shot around the top cylinder (probably from blocked water ports/channels causing high block temps) and the Sump was heavily corroded. Just waiting on parts now- hopefully they arrive soon so I can assemble before I forget what went where!

Some years back, a friend gave me a 6hp motor. Said it was seized up. I thought what the heck, I'll play with it. Got it home on a pretty nice wood engine stand that he had it mounted on. After 5 min, found that it was in forward gear, and the prop was hitting the bottom of the stand.

[@DangarMarine]

LOL. That happens. :)

[@joerillarilla8524]

Lol hopefully you found that out before pulling your hair and banging it with a hammer LOL we've all had silly things like that happen I got a 2.5 Nissan with a long shaft that would always get water in the fuel if it stayed out in the elements I bought a Yamaha and never have any more trouble but my Yama is a 4-stroke they are way more reliable 90% of the time it's a fuel issue with outboards I find that as long as you use them all the time and keep good fuel in them they won't give you a issue. It's when they sit impellers and seals dry up and cylinder walls not lubricated we've been had a little bit of water in the fuel even worse Salt Air around the Rings dead giveaway when you pull the plug and see corrosion

[@germanshepherdsinperthaust4288]

My Johnson 30hp is stuck so I'll give this a try. I forgot to install a spark plug back a few months back, must have been distracted by my kids :( and the piston is seized from moisture getting in. Thanks, the video was very informative.

[@DangarMarine]

Chances are it will be fine. I was also recommended to me below in the comments to try a mixture of coca cola and vinegar as a mild acid to remove the corrosion. Could be worth a try.

[@germanshepherdsinperthaust4288]

I have a Johnson 25hp we used on the weekend and smoke bellowed out from the motor and we slowly made our way back to the dock. The thermostat melted from the motor and the tell tale plastic elbow on the motor melted. I stripped down to the water pump to find it melted. I installed a new pump. Re-installed everything, Tried pull starting this morning and its stuck. Would the pistons have seized up even if I physically had to stop the motor when we reached the landing? Or is it possible to free it up as per your video?

[@freakofnatur101]

I bought a 67 Starcraft fishing boat with a non-running 1959 OMC/Gale Sea king, didn't think I would get the thing to run but I started at the basics, there was compression, so I went onto spark.. no spark, checked out the set-points, they were filthy but nothing too terrible, no holes or cracks, eventually timed those in just by using feeler gauges, spun the flywheel a few times an saw that I had one cylinder sparking and the other no spark, so I picked up a tuning kit online with new condensers and set-points, replaced all ( keeping old set-points as spares, ) .. spun the flywheel again after getting her all back together an bam, spark!.. just threw the recoil back on, a filter on the fuel line ( rusty can will get a new one ).. after a few pulls an messing with the low speed needle on the carb she came right to life and sounded beautiful!, The very next day i found a guy selling a 57 sea king WITH ELECTRIC START!, unfortunately its seized, and missing the throttle rod from the motor to the throttle hinge, but for $25 i felt it was a steal, I'm going to try and restore the electric start system an swap it onto my running motor, and just part this one out, I don't feel its worth it to try and get it running may just be too much time and money, especially considering its 60+ years old and I have no clue how long its been sitting - it was picked up at a site that was being demoed and excavated out in the twin city area of Minnesota. Long story short, I rebuilt most of the ignition system on my 59 sea king, and got her running - first little restore project of mine, this is the first outboard / boat I've ever owned, and now I'm addicted ;).. Definitely going to subscribe to your channel and keep watching! Thanks for making these videos!

Great to hear mate. :)

[@WhakyD]

Love the videos! Thanks for taking us through the steps. Got a 25 I'm about to tackle. It's good to see how you do things and hear your thought process.

[@DangarMarine]

Thanks mate. Good luck with the 25. :)

[@PropanePete]

Pretty versatile workshop. You can bring your car and boat around and have them both serviced while you order Chinese take away or eat in at the Van Lee Chinese Restaurant, which presumably is within a stone's throw away...

[@beachdetectingthemoneypotb7265]

Worked for me , got me out of the shit on ice skates , miracle , now she runs , I didn't have probs with the fuel ⛽️ just the seized up bit , after buying a engine and not even trying to pull the cord before I paided up , big mistake , seller was on board the whole time for refund , but with your video it all came up trumps 🇺🇸for everyone 🇦🇺

[@DangarMarine]

Nice one Tim, great to hear you managed to save another outboard from going to waste. Enjoy!

[@beachdetectingthemoneypotb7265]

Dangar Marine the seller was happier , I knew where he lived , check shit out before you hand the cash over , just before you let him put it in the boot of your car for you , without checking , even if it looks new inside garage Lucky 🍀 this video got me out of it Buyer beware 🍭

[@alvinslovinsky8480]

The video was very well done and helped me with other outboard motors as well thanks for sharing It very much appreciated.

[@DangarMarine]

You're welcome Alvin. :)

[@BigRiverLabrador]

I’m going through the exact same process with a Yamaha 9.9 2-stroke. Outboard was in a storage shed during a river flood and was submerged for several days in fresh but muddy water and this is 4 years later the first time the cowling has been removed even. Going on 3 days now of filling heads with rust penetrating spray and injection oil but no give at all yet with pry bar. As mentioned in video though, I’m not forcing it to the point something will break but applying plenty of force. 🤞

[@terencegillespie6675]

Thanks for your training. I've got a post hole drill, E85 Earthquake, that locked up on me by surprise. Was running and seized after shutting down. No restart. Huh. I never forget oil in gas so go figure. I'll try your method soon. Short blocks aren't cheap.

[@samkamea8603]

This is very best video that it helps me to understand how the engine works. By watching this video I have a fare idea to help someone.

[@leomatos1980]

support 100% on this side. Good Job! Danger

[@DangarMarine]

Thanks mate. :)

[@TheLifeUnderwater]

Thank you!!!!! Saved me 500 dollars, love your videos

[@DangarMarine]

You're welcome Grant, that's what it's all about! :)

[@davidpowell3691]

Try adding an equal quantity of acetone to the ATF, it is the most effective freeing agent I have ever found. Love your work, Stu.

[@DangarMarine]

+David Powell Yes, I've heard very good things about that particular combination. Will definitely try it next time.

[@matthewdenham7400]

Hi Dangar Stu, Thanks for all your great videos. I have one suggestion to all that are trying to unsieze their engine. If you are not able to get any movement at all out your engine despite your efforts to free the pistons in the bores. Check your outboards gear box. As i found with my Honda 15hp the engine was infact completely fine and it was the top bearing in the gear box that had siezed. Hopefully i have saved some one the swearing and confusion that i endured. Thanks again Look forward to visiting the island again in summer!

[@DangarMarine]

Hi Matthew, yes I too have had outboards where it is the gearbox completely seized, not the motor itself. I should have added a step to this video on confirming the source. Sounds like I might be bumping into you this summer! ;)

[@JasonSipe16]

Man, this is a great video, Stu--this one (and another) made me a subscriber.

[@bojanglez4855]

You give me motivation to try to work on this motor now🤣🤣

[@DangarMarine]

You can do it!

[@michaelknapp2500]

Great video. Thanks for all the information. I’ll be going thru your videos to see if you have any broken upper spline removal in powerhead.

[@peak.sidehustles]

This is very helpful and you’re a great teacher, thanks for the advice and I’ll try it on the motor I just got that’s seized up!

[@TheWaterflyer]

I thought you had a chinese restaurant upstairs until you showed us today :-)

[@wolfofrhodeislandx7462]

Keep up the great vids.ive learned so many triks and tips from them! Another handy post...

[@jayroly]

Great video, keep up the good work, they are very informative!

[@DangarMarine]

Thanks Jay, glad you liked it. :)

[@trevorhanlon471]

Good work Stu, Everytime I try to rock back and forth a seized motor, I just seem to loosen the flywheel nut :(

[@DangarMarine]

Thanks mate. Yes, that is a problem if it is really seized. Let it soak with a combination of ATF and acetone then try pushing it in the direction that tightens the bolt only until it moves a little bit .

[@jl.luizaraujo9820]

hi how are you, buddy? I am Luíz do Brasil, and I follow all your videos, I learn a lot, they are very good, congratulations, God bless you!

[@jarlebrve6576]

That fix was as long and winding as a Norwegian mountain road. I love these jobs that really takes off into a comply different direction.The only really hard part is to keep the customer informed well enough so that he willingly parts with his money. We can't work for free. Even if the satisfaction of getting things up and running almost makes it's all worth while.thank you for posting Interesting videos.

[@DangarMarine]

+Jarle Børve Hey Jarle. Yes, this video did take a few unexpected turns! You make a good point about keeping customers informed. Often jobs do turn out to be much more complicated than expected and that almost always means a bigger bill than expected too. A simple snapped bolt can turn a 30 minute job into a three hour job very easily.

[@fw1421]

A seized engine like this may be gotten started but it will never be quite right until the pistons are removed and inspected and most likely the bore needs to be at least honed to remove the pitting from the corroded rings,and new rings installed. This is a stop gap measure.

[@ckm-mkc]

It's a beater boat - changes are it will run for as long as people need....

[@kitten_processing_inc4415]

But I guess using it the way it is won't make the eventual overhaul any harder, right? So you get another couple of hundred hours of motoring "cost free", before you do the eventual overhaul. A lot of people don't really use their outboards to their full potential so a bit of lost power from wear and pitting of the bores and rings won't matter to them.

[@richfraser9459]

Great informative video as always, thanks. (from Scotland)

[@kingfishstacy]

Nice video, Reminds me of when I was a kid working on 2 stroke motorcycles. im 50 now and still a kid hahaha Great vid I love engines and anything mechanical, just don't like the greasy hands anymore.

[@advancednutritioninc908]

Way to work through a series of problems !! Excellent !! thank You!

[@DangarMarine]

Thanks mate, you're most welcome. :)

[@adam56usa]

Enjoy your videos. You’re a regular guy.

[@DangarMarine]

Thanks mate. :)

[@gegeeighth6613]

although I do not understand English but I like to see your video explain very much

[@DangarMarine]

Thanks you, glad it helped you. :)

[@rodashford1151]

Dangar Marine I have a yamaha 3 cyl 40 that stalls when on idle, any ideas?

[@jimbogasoline8559]

Rod Ashford Fuel related bud. Try choking it right before it dies and if it makes it run a little longer than fuel is your problem

[@rodashford1151]

Jimmy Chongo yeah all sorted now, it was a blocked jet

[@jimbogasoline2042]

Rod Ashford Cool glad you got it running!

[@benji6494]

Great video bud...my seized motor is now soaking in a bath of lubricant and 2 stroke oil. ..not sure it'll work as my motor sat in a shed for 5 years... kudos for the information ☺

[@DangarMarine]

Fingers crossed for you.

[@TylerLL2112]

Did she ever free up?

[@PremierProducing]

Your videos are soooo good man such a good teacher man iv watched so many of your videos and they are very good

[@DangarMarine]

Glad you like them!

[@C1iffBurton]

I have a siezed up motor (40 hp 3 cyl. tohatsu), pulled power head to take apart thinking catastrophic damage was done and ready to go internal on it, well all looks fine other than siezed rings, been soaking the rings like you did, how should i go about trying to free up the rings from cylinder walls? with it sitting on a work bench? impact gun on top of crankshaft and go slow? heat up cylinders and try to get it turning that way? not sure other than placing the powerhead back on the motor and bolting back down and using a breaker bar like you did thanks, broken down atv motors, lawn mowers, car motors, but never an outboard motor. you gave me the convidence to tackle my fears

[@DangarMarine]

+C1iffBurton Hi mate, glad the video has given you some confidence to tackle this one. I would be inclined to use the breaker bar without heat as you will get more feel through the handle of the bar and it is a large area to try to heat three cylinder bars uniformly. As you say, you'll need to have it locked down good and tight but it needs to go together in the end anyway. Let me know how you get on. Stu

[@RobFreakDj]

Set fire to it if nothing flammable around, fill the bores with white spirits and light it with a blow torch, make a press using steel and a car jack and press the pistons out

[@alisterdickson4476]

Thank you learnt a lot cheers from Scotland U.K.

[@DangarMarine]

Glad it was helpful!

[@alisterdickson4476]

Dangar Marine yeah excellent as I have a 2 stroke on the Rib I use for getting to my house
