'69 johnson hydro electric shift V4

Maybe if you drove up to Ontario, Canada, racer might help you with it

I guess the plane tickets would be more expensive then what I payed for the engine. )

I have driven 2 hrs to tutor someone in his workshop.-----A retired individual who is repairing older motors as a hobby.

Looks to me that damaged parts were replaced.----And the cause of the damage was overlooked.----Fairly easy for me to say.---Note----I was working at a Johnson dealer in 1968

My suspect was the wrong type oil, but clearly there is more.
I am just a 20 year old, trying his best to get this old motor going again and save it from the scrap as this is what everyone around here would do. Parts have to be imported from the US.
No mechanic wants to work on these motors anymore. So I will have to be doing it myself. And that's why I came here.

They use type C- oil.----But using a different gear oil does not cause immediate damage !!---Will still shift fine !!--On more than one occasion I have shown folks what is wrong with a mechanical device.-----Only to have folks indicate that I am wrong.-----They are still struggling and replacing $100,000 parts because they refused to listen.----All I do now is chuckle when I think about or hear about their struggles.----Remember , I can not see or touch your motor lower unit parts.

Today's telecommunications services offer lots of possible alternatives to
help out far away folks in need of support.

In my younger days in telecoms the "videophone" was just a dream for the future to come.

Today everybody walks around.... with a "videophone" called IPhone and the camera is built in!! or.....posting up a short video on Utube works to !

During the Covid peak videoconferencing was the way to go to teach kids at home. everybody can now "zoom" around the world to teach things

"where there is a will there is a way" .....said the fortune cookie

My take/version is "Where there's a Will, I want to be in it"

I am currently in my exams as electro-mechanics but I will keep updates on what I find when I take the lower unit apart. Given the location and weather, that is going to be a day job.

Thank you all so much for your input!

Possibly somebody had a stuck shift piston in the oil pump, so he honed the bore in the pump to free it up and provide more clearance for the piston to slide. Nice idea, but that also increases the leakage past the piston (remember, it has no rings like engine pistons). Now the lower oil pressure applied to the piston because of "blow-by" is not enough to shove it all the way back for reverse engagement.

There is an o-ring in there to prevent leakage.---Even after honing.

If that is the case, it will most likely need a thicker o ring.
Going to take apart the engine next week, so we will see.

Nope-----O-ring will just need to be replaced as clearly posted in #5 in this saga.----So take it apart.----See what is wrong.---Repair as needed !!

I said, WHEN they honed the bore, there will be a thicker o-ring needed. But it is less likely that it is honed.
Like I said, I will take a look into fixing next week!!

Good luck with your project.----No need for further input from me.

I admire your determination Maxwell. Your motor looks like a decent example.
You are getting great advice from experienced members here. Better yet, it is free.
Also, good luck with your exams!

 

[stresspoint]

yep , very experienced people here and some and some with first hand knowledge have given advice.
good luck with the project.

lucky you didn't choose a modern auto trans as a project for your exam .

Mine is a Belgium motor,

Forum guru Joe Reeves told me that OMC changed wire suppliers in 1968 and had a huge problem in the years following. I do not know when that issue was corrected and if it was only for USA-built motors. Wanted to share that info with you and wish you good luck with your project.
