That's a salt water issue, not a 2 stroke issue.
Exactly
🎉
Yeah, exactly
hey without two strokes out boards would not have happened.yeah sure they are smokey but i just love the smell of burned two stroke oil on take off.i went to MMi in 1994 two stroke school a very big thing back then because the only other motor out there was a car motor on a boat. so long live the two stroke motor
I've seen 4 strokes with exactly the same corrosion issues...
100%, I'm very wary about buying a 4 stroke that's more than 10 years old, for that very reason - and 4 strokes are MUCH more difficult to repair!
If not worse than that
I have used JB Weld on boat engines before, but I never told anyone because I thought I would be made fun of. I didn't realize that it was a common practice.
I've used it on car thermostat housings, that's what it's meant for patching blocks
I switched to full synthetic 2-stroke oil in EVERY 2-stroke I own. Even lawn equipment. I have a Husqvarna 2-stroke leaf blower. 20 years old with the factory spark plug still in it.
Love your videos man. Glad I found your channel. You’re helping me with my boat project as we speak🤙🏼
Awesome! Thank you!
Good ol' JB Weld has saved me quite a few times over the years.
Once you've dialed/fixed it up, it'll be a great motor. More or less been through the same with my V4 130 Saltwater series. I'd say it's taken about a year work on and off again until it's perfectly sorted. The Rydlyme worked brilliantly with my motor, flushing from 12pm to 8pm.
I'd say the only difference between the United States and Australia though is that we've got plenty of mechanics that will work on 2 strokes.
Always honest and to the point; reported issues are presented as you find them! Love the education! Love JBWeld BTW!
Brother in Venice,FL
Much appreciated
Just changed my water pump,thermostats and poppet valve on my old V6 mercury. Found salt crystals in all 3 and corrosion. The water jackets to the motor looked really clean and no corrosion beyond the thermostat housing and poppet valve in eye sight. I'm sure there's more salt in the engine I cant see. No flush port so I'm hoping the lake water will dilute and eventually flush the salt out. I'm going to be staying fresh water until I'm a better boater with more experience and a salt water engine 😊. My usual luck I had to drop the lower a second time I totally missed the water tube and shift rod connections. The gasketsthey gave me for the poppet valve are thicker than the originals. That's fine for the valve housing against the engine but the second gasket being thicker between the cover plate and diaphragm housing made a gap between the diaphragm and the cover plate that allows the diaphragm to be unseated and water is coming out of the deep hole. Have to take that apart today and put a thinker gasket between the housing and cover plate. Arrg 😂
I had that problem where I broke 16 of the 18 bolts, the way I solved it, and it wasn't my Idea. I took a piece of hi carbon steel drilled it and then put a slot and was able to bolt to the engine housing and use that as a guide for the drill bit to drill out the broken bolts, you have to heat up the guide hole and harden it, it worked perfect, I ended up putting Heli coils in.
Love how you've made like 8 videos off the same thing lol. I don't understand how this is specifically a 2 stroke problem though
It's not, newer 4 strokes are worse, in my opinion
Gday mate thats one thing with older engines every turn there is a problem some easy some not i had a similar thing with the thermo housing on my 92 i filled it with basically the same type of stuff but not a liquid like yours its lucky i wont use this engine but if i sell it someone is getting almost a full rebuild to an extent it was worth it just for the experience as now my 4 stroke will be easy as if i ever have to work on it and it has shell bearings yaaaaaaaa .
I liked this video because I love the channel but the second the drill bit broke I couldn't watch. LOL. Pack a lunch and maybe dinner and have at it, Good luck bud!
Your video goes to show that is worth using to time to save your motor :)
What would be a motor fail that would make it not worth even trying? EMM? Powerhead? Crank shaft?
Glade you hate two stokes. I hate 4 stokes. Love pulling the motor to change an oil seal that blew oil out the lower unit and all over my driveway. Lucky I wasn’t on the water. Been a year now, after having to drill out four Bolts and buy metric taps. Learned that metric has three thread types not course and fine. I also had the joy of a broken easy out. Do not know why to this day they don’t use Anti-seize on the bolts of salt water model engines. Now Johnson is gone, the Suzuki cross over parts cost twice as much if you can’t get them. Once I get it back together, my salt water days will be over with.
Had the same motor and it was bullet proof. Never touched salt water tho. Great video BTW
Thank you.
Surprised you did not replace the lower crank seals at the same time, while the power head was off.
Time for a repower. Say hello to a four stroke!
I hate 4 strokes
@@Yamahaoutboardguy5090 It's now the standard. The boating world has moved on.
@@A5JDZK that doesn’t stop me from hating them
The same thing would happen with an old e 4 stroke. If you had soaked the bolts with penetrene before you tried to pull it apart you may not have had the problem!
Have a mercury 150 saltwater that I am about to try to pull the powerhead on. It's a year 2000 model carbureted 2 stroke. I think I broke a piston rod because it shut down at 1500 RPM with a clanking noise but it still rolls over. It was caused by me replacing the water impeller and forgetting to put the key in the shaft and then I let it run with rabbit ears on way too long waiting for it to start spitting water before I shut it down..started and ran fine after I pulled the bottom end and replaced the key on the shaft but unfortunately, the damage was done. Took it out for a mile on the water at a slow troll speed and she quit.
I have the same corrosion hole in the top of the my old 60 Yamaha instead of fixing it I fitted a second water tale tail so that way I could see the motor was getting water at the top of the engine it worked great until the gear shift broke in the gearbox from corrosion Im shore there's a coppel of years that Yamaha had shit alloy in the late 80s early 90s
Any idea on the hours? Do you think this motor was regularly flushed?
Did you put heat on the bolts or is that not an option for the water jacket? I have an 89 version of the same motor. Agreed about love/hate. Saltwater is my only option so I am just having to live with it.
Could you machine the surface to help get rid of some of the pitting?
In the video it looks curved
Have you tried using a low heat aluminum brazing rod to fill the voids that are corroded in the water/exhaust jacket? Stuff is super easy to use !
I doubt you could get the block hot enough for brazing rods to work
What about tig welding to add material to those spots on the manifold and grinding it down- like new. I have done it to motorcycle engines with good results.
MIG, TIG, even stick. Whatever you can weld a nut on with. It doesn't pay to use junk hardware store drills, taps and extractors either.
Can you replace the cylinder sleeves in the older merc two strokes?
It’s a Yamaha issue with using mild steel bolts especially on trim pins and bolts. Why don’t they use 316 stainless ?
There is so much more salty in USA than in Norway 😅 Luckily we don’t have so much salt problems on two strokes
And this is why you spend a little extra to buy a freshwater two-stroke don’t buy motors from south Florida no matter how many strokes they make😂😂
that hole you filled looked like a sensor hole. I thought you could tap it and put a screw in there if the jb doesn't fix it
if there was enough metal, i wonder if tapping and throwing a bolt in that block hole would have been a reasonable fix.
best thing for getting broken bolts like that out is a tig welder
I broke a tap off in a 70 HP Evinrude yesterday.(cooling /exhaust) These engines don't have the normal divider plate. Haven't done that in the twenty years I've been in business. Guess I get to try the welding to a nut trick with the mig to resolve this problem. Six of the bolts broke off despite using every finesse trick that I knew. Sometimes they are just too far gone. Had all but five removed and cleaned up used left hand drill bets stepping up sizes. A couple never would spin out and the tap just clears out the thin layer that is left after drilling. I got in a hurry with the tap chucked in the drill, I knew better.
Ran across this for removing broken taps if you ever have the situation. I didn't know they existed , I'm sure it's common knowledge for machinist. Says it's designed for use in a mill but this guy made it work with his drill. ua-cam.com/video/dAH7xLwnxe4/v-deo.htmlsi=762d1vckdTHs4qPO
wish you had included fixing the stripped bolts-they suck and i like to see how others deal with them-
Do you just mean old motors vs new motors? Why would an engine get more corroded just because it’s a 2 stroke
4 strokes are more likely to corrode I think, because they make them out of crap alloys to make them as light as possible. I went 4 stroke, said I'd never have a 2 stroke again, now I have an old 2 stroke that's outlasted 3 newer 4 strokes
Aluminum pipe plug would work best.
Drill a hole and tap out to 1/8 pipe plug
This is an issue with it not being maintained. I’ll argue with knuckleheads on here saying you don’t need to flush your outboard after running in salt. These are the motors these people used to have.
I had a 2001 150 Yamaha that I just got rid of and had since new. Still ran, sure there was some corrosion but nothing like this. Never had a leak either. Maintain your stuff people.
J B. Weld I saved my ass a few times.
You wouldn;t wanna use JB weld instead of RTV?
Hate them? Mine is 1993 and…. Iv spent about $3000 on maintenance and parts since I got it in 1995. I think I’m saving money and staying out on the water.
If you can't keep those carbed Yamaha 2 strokes running its best you find something else to spend your money on rather than boats. You can save yourself hassle down the road by removing bolts that are easy to get to, put some grease on the threads and retorque.
Looks like it was never flushed!
Hey I bought a 85 hp yamaha took it out the other day ran fine then broke down on the water. I replaced the fuel pump and filter but can't get it to start. it will only run for like 10 seconds if I use starter fluid does that mean it's my carb?

I’ll come right and say it: I miss two stroke engines! I live in a fresh water area. I loved the smell and miss the sounds of them.
I know that feeling!
Why is that a two stroke problem? It’s an old engine in salt water problem , fours can do that also 😢 I love my two strokes and worry myself sick that my four strokes will suck a valve or spin a bearing . Ring free in two stroke got me over 1500 hours on ox 66 200’s
👍👍👍
Change head gasket
You seem to know what your doing on 2 stroke motors. Did murcurt evey make a 135 hp in 1988, that did not pee all the time?
If you look for something to fix you'll find it
yeeeee
When sanity and common sense comes to the town all around USA!!!! Loving it!
👍
That’s a not being flushed problem. Not a 2 stroke problem.
scotchbrite I swear they were invented by machine shops. guaranteed your mating surface is ruined now.
Woof. nobody taught you how to extract bolts bro..weld it.
Yah really gotta work on the outro man, like leave us at a stopping point LMAO
Lol. Noted bro.
Yamahas just do it
This engine is on hospice care at this point. Soon time to throw it in the scrap heap. Too much money and time into a crust bucket
What exactly of it made you think this?
"Two out of four major catastrophic issues!"
Excuse me but whos drill bits are you using and who brought those cheap drill bits?
There's only ONE catastrophic issue here and its the free hand DIY repair operation modus.
"You just can't pay people anymore..." is false dichotomy; because a drill rigg would have made this job much easier and less friction free, but then again there would be any click bait video. All the best. Cheers.
This guy is a serious joke! When it comes to a 2 stroke or 4 stroke there is zero difference in Salt corrosion!.....Its up to you as the owner to prevent salt corrosion 🤦♂️!!!!!!!!
Such a baseless and stupid title for the video. Secondly, that motor is about how many years old?
Let's see an equivalent four stroke after the same number of years,if it's still running.
what’s a 2 stoke
