1977 power trim

[nebguy]

Hi all. This is my first post, so be gentle. I have a 1977 Johnson 115. The power trim had been acting up (seemed weak and very noisy). Today after fishing, I decided to do something about it. So I took the cap off the top. I couldn't find anything that made sense, so I tried to put it back together. Now, it won't go on right with the springs and brushes and all that. Needless to say, the original problem isn't fixed, and now I have a brand new problem. Any help would be great.

Thanks,
Eric

Re: 1977 power trim

What you took apart was the trim motor. Post a pic of what pieces you are unsure of and we will be able to help you get it back together. The original problem was probably due to low fluid. Check to make sure the resevoir (on the starboard side, or right) is topped up with fluid. There will be a slotted screw in the front of it, that is the fill hole. Fill it up, cycle it a few times, then re fill, it is self bleeding. Ensure the manual release valve is closed and tight. Let us know what you find.

Yep, low fluid. Once you get the electric motor back together just add fluid by removing the big screw (about midway up the reservoir) and add. Run the engine up and down a few times and refill.

You should have come here first. ;-)

Yeah, I should have come to someone before I messed with it. When I took that cap off, I was looking for the fluid level. Thanks for the advice. As soon as I can I'll put some pics up. The parts are so dang small on these things! Again, thanks for the advice. However, I think I may just have to take it into a shop.

The motor has to be sealed water tight. For obvious reasons.

I had to replace my trim motor on Monday after having it rebuilt by a local alternator shop (as I am also a newbie). I asked the guy who rebuilt my motor the method he uses to get the spring loaded head back on. The suggestion he made was Dental Picks. I thought that was a clever idea. The rebuild cost 69.00 so it sure beat buying a new motor.

Another problem I ran into before I went to the pro was that I did not have the trim motor shaft aligned correctly in the resevoir and cracked the cap (hence the rebuild
