DANGAR, Love those wiggle head extensions! I was working a job with a 2nd man & he pulled out a wiggle head extension for the work. I had never seen one before. He let me examine it & use it & I was sold! Next day at work, he walked up & handed me a package of 3 wiggle headed extensions : a 12" a 6" & a 3". It was such a nice gesture I bought us lunch. I use them regularly in my home shop now I am retired. Dig you videos. Metrics always confuse me. When you say your pulling a 10 mil bolt I dunno if you mean a bolt with a 10 mil head OR a bolt with a 10 mil shank. I'm learning. It's a joy to watch a man do good work.

What a great video, one of the best you have done! For me, it gets across the point really well that outboards operate in a really harsh environment, and when the years accumulate and something goes bad (e.g. bearing failure), then you find parts are going to seize and / or break, and very likely the motor is beyond economic repair. Many thanks.

Got one coming up possibly. A neighbor that lives nearby has a 83 8hp Suzuki that is seized. I told him I would help him try to get freed up but if not will take it if he plans on dumping it. I would take it apart and use a press to push it piston back and forth with lots of lube and heat if needed. If I'm lucky with cylinder cleaning and the piston just needs new rings with replace the main crank bearing and put it back together? Maybe? It would make a good video either way😁👍

Looks like you had a tough day. Sorry, that some days are just like that! I just had a Johnson 40 HP that had perfect cylinders, but would not rotate completely. I figured it was a ring stuck or a bad bearing. Was going to take one with a scored cylinder, combine the two and get a good engine out of all the parts. A car mechanic friend was over, and decided he could get it free. He did, but scored a perfect cylinder while doing it. Lesson learned - keep car friends away from boat motors after they have had a few! This week, I had a 115 with perfect compression, hot spark, good timing, etc, etc. It runs great at speed, but it simply would not idle. Once above 1500 rpm, it runs like a champ. I did many, many things, but nothing helped. Finally, after having two other mechanics over to brainstorm with me, and getting nowhere, one asked if I would sell it to him as a test monkey. I did, and now he has it. Only the second motor in memory that I simply couldn't figure out. Does not feel good! My theory is that is has a vacuum leak on the bottom of the motor, probably the bottom seal. Somewhere the spray can't reach. At higher RPM, the engine produces enough vacuum to run properly, but at idle, the leak is too much, and it just dies out. No sneezing, coughing or popping, it just slowly dies. That's my theory, at least. It will be curious if Josh can figure it out. I hope he can. Thanks for the video, as usual!
@DangarMarine7 жыл бұрын
Bummer about the Johnson, don't you just love it when you mates help! Sounds like a good theory with regards to the 115. Vacuum leaks do tend to have much greater effect at idle. Some outboard really are baffling some times.

Had an old duffer explain to me years ago to not use the puller to actually pull of the flywheel but to use it to put a strain on it and tap the flywheel with a non-metal hammer. Keep adding a little more strain (half a turn) and keep tapping on the wheel. A little lube and a little heat maybe but go slow with the puller.

That certainly is a good technique. Need to be careful with heat due to the wiring beneath the flywheel but it is amazing how often a relatively light tap will release something once it is under load.

I realize you work on several outboard brands, but the OMC universal flywheel puller is a must for getting these flywheels off. 99% of these removal headaches will be avoided for sure. That was a very creative method for splitting the crankcase with the stuck powerhead bolts! Please be sure to remove the crankcase alignment taper pin first though, before the crankcase bolts, the case halves will then split easily with just a few raps on the crank with a heavy plastic mallet. Too bad this engine is a finished for sure, unless you can find a decent used powerhead...
@DangarMarine7 жыл бұрын
Yes, having the exact right OEM tool definitely makes a lot of jobs easier, that's for sure. Unfortunately we are primarily an automotive shop so all the money goes into tools like spring compressors and radiator pressure testers that are no use at all on these outboards! As you say, second hand powerhead from a wrecker is probably the best way to get this motor up and running again.
@RudyNortz6 жыл бұрын
I always treated the flywheel "puller" more like a tool to put tension on the flywheel. Put the tension on by hand so it's fairly snug then tap (pound?) on the flywheel. Little more tension and some oil-like spray and maybe a little heat and more tapping. Keep doing this a bit at a time rather than doing it all at once. Less chance of breaking a bolt and/or splaying out the center bold.

I have a 1994 Mercury 135 and my head and piston looked the same as this one but my failure was the rings not the bearings. My question is, should I bore only the scored cylinder or all 6? The machine shop, sight unseen, of course recommends doing all 6 at a cost of $80 per cylinder. That also means that the pistons are going to cost 3 @ $140 each and 3 @ $160 each. I am used to working on auto engines and we would just bore and sleeve the scored cylinder but the machine shop said something about the cylinder walls (ovaling) out??? You recommendation would be greatly appreciated as the savings of doing only the (bad) cylinder is huge!

Great video here, this helps me understand these motors better. I have an '80-something 60HP Johnson 2 stroke that died yesterday. Running nice and smooth around 2k rpm then it stopped quickly. It had run nicely last year, but this was the 2nd outing this year. Upon manually turning the flywheel I discover quite a bit of grinding when turning in the running direction, but no grinding in the other direction. Of course it is in neutral. I can turn it 360 degrees, and like I say it turns freely in the reverse direction. Nothing getting jammed under the flywheel, which is off now. Because it turns without grinding in the reverse direction, I'm thinking it's not bearings. Am I crazy for thinking this is worth taking the lower off, then the power head to see if it then spins freely in the other direction? Maybe peek in through the reed valves with a scope. I think the motor has just been in freshwater, so bolts haven't given me too much grief...jinx. It also will idle intermittently until it abruptly stops. Tried that 3 times now before discovering my grinding. I'm thinking, hoping something might be just binding the driveshaft???? IMO if it's bearings I will feel grinding in both directions.

99 was last dance for omc, everything was out of spec, trying to keep pace with Merc and yammie.

I have just put sealed bearings in 5hp Tohatsu 2003, do I need the pressure lubrication hose to lower bearing now? Thanks Stu.

It's probably not the best idea, but I find that if you put some tension on the puller an lightly tap down on it with a hammer the fly wheel usually pops off.

Hello I am looking for a tear down and rebuild of a 1996 Johnson 200 HP Ocean Runner video or book. I would like to rebuild my Johnson outboard. Any information would be great! Love your videos! Thanks

Is there a way to get some grease on those bearings without tearing it down? Just curious if there is some kind of preventive medicine, have you ever heard the term don’t drink the cool-aide? Or they’re drinking the cool-aide? What is that bottled substance? Kool-aide?

just hone it and throw in a set of rings, how good does it have to run? most people use their boat 10 hours a year anyway.

Why did the bearing fail? lack of lubrication?

Can be a variety of things, but this outboard had sunk in very muddy salt water about six months ago. Combine that with being almost 20 years old and used every day...

Nice video. I ask the same as Johan sundberg. Why do the bearing break?

Hi Stu, excellent video. I have a Yamaha 15 2 stroke where the main bearing failed. Is there a way to remove the centre bearing? How do you split the crank. Not sure if it’s worth repairing but I like to have a go just for the craic. Any help would be greatly appreciated. Thanks
@DangarMarine7 жыл бұрын
Thanks Lorcan. Unfortunately I don't think you can replace that centre bearing. I spent ages trying to find an angle I got get a shot at pressing the crank apart but no luck. Next time I was at Yamaha I asked about it because I thought it was odd and they said no go, whole thing needs to be replaced.

Let's say my 1985 Johnson 25HP is cranking but not fast enough. Only getting 50 PSI. Battery, starter, solenoid are all good. Its really hard to turn the fly wheel. Any idea what the issue can be?

hi Stu this video is very informative even more so because I have a 50hp Johnson but mine seems to be fine so far no problems with it at all what I'm wondering is if any of the parts off this motor would still be useable & would you part it out in particular starter motor set up & Power trim / Tilt set up as my outboard is Manual start & manual tilt would hate to think they were just thrown out not that I think you would if they were of any use thanks for the work you put into the videos for our entertainment

Yep, when motors like this die I always strip all the useable parts off it and store them away.

are the needle bearings a serviceable part at a given interval? how do you avoid that failure.
@DangarMarine6 жыл бұрын
Generally not, no. This outboard had sunk a few months earlier so I would say that was a major contributing cause.

so should last the engines life until a rebuild. yes forgot about the sunken part makes sense

thank you for the vid. I have a 96 evinrude 40. Can you put one of those onboard battery chargers you installed a little while ago on this type of motor?
@DangarMarine7 жыл бұрын
Yep, sure can. If you take a look on MarineEngine.com you will be able to find the regulator rectifier that goes with your motor and order is separately.
