Customer Say Outboard Cylinders Fill with Water

[@waynegalvin4639]

I had a 1974 135 hp Silver Starflight Evinrude and it had the same style trim and tilt. I liked those old OMC motors and that one is in exceptional shape.

[@dlv444]

That thing is in amazing shape. So cool.

[@peterjensen6844]

Haven't watched the whole video yet but I'm betting its the exhaust gasket. Happened exactly like that on my 74 50hp. There are several REALLY thin spots on the water shield gasket that lets hot exhaust get blown by if the water flow isn't working ideally. Especially if someone runs it on muffs and starts at high idle where the explosion ends up in the exhaust galleries due to lack of back pressure. EDIT: Yup! That's exactly what the water gallery gaskets on the exhaust cover I had looked like. And yes, the bolt issue ugh and I ended up custom ordering them and you can get the exact ones but they aren't cheap.

[@Sluf7]

Great vid I have 2 x 70hp Evinrudes 1973 vintage which are immaculate on my 24 footer. Brilliant vid in now I know what to look for.😊 they will get thorough going iver once resto finished later this year😮. Keep at it chap😅

[@birdshots]

Really enjoy watching you work Brandon. Wish I had more of your patients and determination. You've taught me a lot about OMC, and I really appreciate that.

[@davez4172]

Very nice boat and excellent repair! I have a '72 Johnson 65 which is very similar. I get my boat out about once a week for 6 months out of the year in New York State. It sat for decades due to rot, but new deck and transom got her a new life. There is still a lot of life left in the motor. I wish I had power tilt. I have motor envy now!

[@davez4172]

​@@stephen8117 That is interesting. What changed to gain the extra 5HP?

[@slalomking]

We had a 70, it was the diggingest motor ever for pulling out skiers. Had it 7 years in the 70’s. A great running, powerful motor

[@jpotts8814]

I have a great junk pile of these triples due to this problem. There was a tech bulletin and update to the exhaust plates. The plate warps at the port allowing pressurized water to blast into the jug. The fix is find an 80's parts engine with the thicker port plate. Generally I find a resurface of the plates gets the engine a couple hours of run time before the leak starts again. BTW my manuals call for QL77J4C plugs. Not surface gap.

[@andronclock1]

Man I would really like your help as Im dealing with the same issue and you seem to know a lot about it. My 1986 49ci powerhead has the same issue and I have tried to fix it once now and it has leaked again, I have put in so much work on this motor this last year and im losing hope, im considering just junking it and buying a newer 56ci 3 cylinder. Do you have any tips to make it work? Some kind of gasket sealer? Do the thicker exhaust plates from later motors have the same bolt pattern?? Any help appreciated thanks a lot

[@ralphbarker7791]

You did a great repair job. Some of those dealerships crack me up when they say that they do not work on vintage outboard motors. I can understand why as well when they are charging over a $100.00 an hour, and a lot may be wrong with the old motors etc. More money in your pocket, and it is good that a skilled mechanic as yourself is in that area too.

[@ct1762]

2 words: stuck and screws. the other thing is 90% of the guys that knew 2 strokes are long gone. you'd be shocked at how todays mechanics wont even touch a carb let alone rebuild one! takes me 25 min.

[@dsciarrino3663]

No more

[@k.whiking4372]

@@ct1762 I'm a former OMC 2 stroke Tech and left the trade in 2015, I knew nothing else but Johnson and Evinrude 2 stroke and couldn't make the transition to 4 strokes. Can't teach an old dog new tricks.

[@danielrobert7181]

Sure is a pleasure to work on such a clean motor, they very very rarely Come in in such a great stade ! Thanks for sharing, Brandon.

[@hxhdfjifzirstc894]

This thing looks like it's been taken out once per year, at most. It's great that you were able to repair the motor, so this boat can go out once per year in the future.

[@randymiller1604]

As a retired, OMC technician, I can say you did this job absolutely correct by the book there is a very clean motor deserves to be taken well care of great video again good work

[@mattd8668]

Nice save on that one ! Nice boat and motor combo. The yellow and green go well together too

[@JamesSmith-jr2rc]

Brandon you sir are a excellent mechanic.

[@95rman]

Great video! I really liked the bolts in the cardboard trick! Very cool old boat.

[@TheRealKlinky]

"My arm's a little tired from patting myself on the back"😂😂😂😂😂

[@Acelachaser1965]

Good to know. I just put a replacement powerhead ($100 eBay find!) on a ‘73 Evinrude 65. Keeping all the spare parts from the old blown block. Just gotta cure some carb needle issues, adjust the shift cable and get her on the water.

[@goatwhsprr]

I am quite the expert on those triples. I have parts for that motor if you want. The absolute best performance enhancer for those 70s 70-75 are performance reeds. Not a high dollar part but man do they make a world of diff

[@ct1762]

man thats a clean motor! Still lucky to get all those screws out. exhaust plates really need to be taken to a machine shop but then again if they are under .004'' warped the gaskets will seal it just fine.

[@davidboscaljon3787]

awesome video!! such a nice looking boat. Glad they found you to work on it. funny to here your daughter in the back ground, love it. nice to see you trouble shooting the problem, not like most places (we don't work on that old of boats!!). wondering if you have found any info. on the tilt and trim unit? looking for the hydraulic flow diagram.

[@raywilson9450]

Ouch, boats and motors I worked on when new in the mid-seventies are now antiques. Boat yard I worked at sold MFG boats, and their equivalent to that one would have been the Gypsy. And that was a popular color, too!

[@miketee2444]

I'm a Merc. Fanatic but will give credit to these triple OMCs. Anyone that knows smokers should remember, cylinders like working in 3s and 4s or multiples of. I usually check clearance and toss the head gasket to get the last life outta these old OMCs. They like compression and good fuel.

[@BerlinScott-m5l]

I would love to have that as my weekend cruiser.. That boat was such a freaking beauty. Great work.

[@plumbucket65]

Beautiful older boat you did a great job fixing it

[@victoroneschuck4139]

Hi Brandon. You do A-1-A on your videos. I have the same problem on my 1990 johnson 40. I did what you did on this video, plus replace the water supply grommet. I'm still getting water in the cylinders. A small amount, but enough to notice. What's next for me? I did not detect any cracks in the block etc. I also inspected the Reed block n changed that intake gasket. Thanks bud. By the way, you must be related to Max Muncy from the Dodgers!!

[@stephencroft761]

28:30 FYI denatured alcohol is fantastic at removing that gasket sealant. Even after it’s set up.

[@k.whiking4372]

Always use gasket sealing compound on OMC head gaskets, Having just said that in fresh water use it 's not earth shattering if you don't. These are the little things you learn as a factory trained Tech. Also use QL77JC4 spark plugs not surface gap, the ignition system does not quite generate enough oomph to jump the auxiliary gap as well as the surface gap. It will also idle better (less plug fouling) and start easier.

[@lifeisfuneh]

I'm so impressed with your skills! Thanks for the great video!

[@georgeanddaddecker7563]

I would use Permeates High Tack with that. Makes a very good seal with two stroke marine applications.

[@mikecalvin1402]

I believe you do some very honest work.🎉🎉🎉🎉🎉😅😅😅😅😅

[@fwflyer78]

Nice work on the repair!

[@tonyowen_seagull_guy]

Love to see freshwater motors or motors that folks flush out the salt...here on the west coast a number dealers will not even change out an impeller for less than $350 up front...then the customer says the motor is not worth $350...Salt on the Pacific Coast is nasty...some dealers will not work on a salt water motor over 10 years old...

[@zook909]

That boat was such a freaking beauty. Great work

[@machew2009]

Im in MN and i love working on them old outboards especially evinrudes

[@2-STROKEFUN]

I would love to have that as my weekend cruiser.

Wow, what a creampuff museum piece of a boat and motor.

Heard you mention AZ in video. Interested in having a 1975 Evinrude 115 v4 worked on. Please reach out. Thank you for great educational videos

[@stevehalverson4315]

I enjoy watching your videos anyway but this one today with the show being stolen by your youngster was the best yet !! 👍🏻

[@fishydubsfishing6516]

The good old permatex Aviation shellac I can't believe they still make that stuff

[@MexicoPescadoro]

Hydrolocked is the word you were looking for.

[@Mjc103]

Might want to look into getting an induction heater for bolts and nuts when you don’t want to use a torch.

[@nathanielfischetti7912]

I worked on this boat this spring and found the head gasket leak,I live in MN and just happened to see this video

[@6Tonjack]

Yes every part of that boat is original. The wiring how ever is not. I did the wiring about 7 or 8 years ago.

[@L2fish]

I believe this is what is wrong with my 1964 28HP Speeditwin.

[@jameshealey27]

Great stuff as always!

[@danschmedeman9418]

my 0ld 50 hp Mercury is not getting water and it apprears it is leaking at the top of the pick up tube. Not from the seal around the top of the tube but out the side of a fitting. I;m guessing the bleed hose came off at the bottom. You can see it looking up from the bottom. Can it be fixed without removing power head?

[@T.D3711]

I have that same motor is there anything I can do performance parts wise to get more out of the motor?

[@gautevaland879]

Well done!! Thank u for sharing!!😊😊 Gus🇳🇴

[@iantyler4045]

That boat came out of a time machine! Even with such low hours corrosion still presents it's ugly head.

How's the water situation Lake Mead and Lake Powell?

Good Job…. At a Marine Shop that would have been exorbitantly expensive.

When they do start, they sound like they're going straight up!! Well, he takes off across the lake, like all same, courteous, responsible boatmen do. On his way out, he takes 2 fishermen, & 1 waterskier.............

I want to put a pumpkin on my head too.

i dont have this motor but have same tilt and trim i gotta find out where i can get a ram seal kit

[@ATStone]

Your kid is hilarious

[@BrandonsGarage]

Which one, the pumpkin on the head, or moving the tripod to watch the screen while I record?

[@leegoldsmith6552]

I had one of those outboards for years water only comes out of those ports when it’s in the water never from the hose

[@dont-want-no-wrench]

you need a better sraight edge, the flexibility of that one could mislead

[@ronalddavis]

a scale is not a straight edge anyways

[@seriksson9721]

Grease or loctite on the bolt threads, what do you think?

[@bennyblanko3]

Thanks! I learned some stuff ...

[@henrycole8705]

I had a 60 horse in the 90s exactly like that. on a 17ft glasspar

[@6Tonjack]

Garage kept from day 1 not even joking.

[@franklinrhodevelt6441]

Anti-seize on the bolts, not gasket sealing compound.

[@kenskip1]

Brad, I would have put the lower unit in a trash can and let the engines pump circulate the water. JMO Ken

[@tyronerautahi9705]

Nice bolt hack. Job well done. 😊

[@khg8519]

The wiring is usually the first thing to go west you cant even fix it the corruption travels inside the insulation lucky the 2 stroke is a simple beast - does this model have reeds

[@dirkdirk4108]

Nice work and my one are also all day on mindgraft

[@stephenbonaventure9423]

I am assuming that you are or had to replace the exhaust baffle plate because it may be compromise with a hole which is allowing water into the cylinder. I am having the same problem with my 50 hp mercury is in the shop as of right now lol ran my 50 hp mercury Couple weeks ago ran great for about a mile and the bottom two cylinder started dropping off, 😂water in the cylinder not a lot of water, but it doesn’t take a lot of water to kill a cylinder. what’s the old saying water and fuel does not mix. 😂

[@rok7980]

Brandon, Is there any good way to remove a cylinder head from an old outboard without breaking a head bolt? So far I am scared to try it. I have an old 1987 88hp Evinrude. I had overheat problem, replaced T - stats, and cleaned water jackets. I Broke a couple bolts on water jackets but was able to get them out. Still get overheat alarm once in a while. I want to remove heads to change out rubber water diverters but I am deadly afraid of breaking head bolts. Any suggestions? Thanks.

[@grahambarton1942]

If you can get at them, it’s a good idea to give them all a good whack on the head as it tends to break the grip of all the corrosion and oxide that builds up in the bolt hole. Heating the block with a propane torch can expand it and loosen the grip it has on the bolt. Also work the bolt both ways back and forth once it undoes a little bit. That’s because gunk gets caught in the threads and the bolt can become tighter as it unscrews (when ch seems counter-intuitive. CRC or diesel/penetrating oil also helps.

[@evanhofmeyr-tg1gl]

Great vid. Love the kids. 😂

I wonder what a job like that would cost, seem really labor-intensive.
