I have a 1976 (i believe) chrysler 105hp that I am working on getting back in the water. It is my grandparents and haven't been in the water since 96. I wanna say that I know diddly squat about boats and am having a blast learning, I need help with the trim motor the cap has been loosened and is slightly popped up and I cant get it back down what do I need to do? I haven't tested of it still works or not. would it be a good idea to take the cap off the rest of the way to look inside or just buy a new motor?

Was it sitting outside uncovered with the cap like that? Looks really corroded in that pic.......https://forums.iboats.com/threads/awakening-a-sleeping-outboard-by-boatbuoy.158032/ Check out this link for the rest of the motor, since it sat for 27 years.

Sadly yes. The boat went through a lot of neglect through the years, the floor is gone and there was an attempt to steal parts off it, that's why the cap is undone but it dosent look like anything is missing and It still has pressure.

I would bet that motor is toast......also, if the boat is the same year as the engine, 1976, and been sitting outside uncovered for 47 years, with a rotten floor.....then the stringers and transom are probably rotten too. Assuming this is an old fiberglass boat....they rot from the bottom up....so if the floor is gone the structure may be too.

Look the boat is good the motor is good only the wood floor is rotted out again I wouldn't be worrying about replacing anything if it wasn't. The only reason I didn't check the trim when I had the motor started was the switch was missing from when parts were robbed off it. I just need to know how to get the top of the motor put on or where to order a new one

You might check MasterTech marine or Franz Marine for a new motor....doubt that one you have is any good.

I see this is the second time the floor has rotted. Putting a new deck over rotten structure is cosmetic at best. I would drill some core samples in the stringers and transom just to be sure. If the wood shavings come out dark and wet....you got rot. If light colored and dry, probably ok. Fill the holes with marine sealer. Why not check it while the floor is out....is all I'm saying. Better safe than sorry.....a rotten fiberglass boat is not safe on the water.

I'd bet a new motor is in order.
Take the plug off the reservoir and see what the oil looks like??
If it looks good then you might just need an electric motor and not the whole thing.
You have a 2 part system: top is the electric motor, bottom is the pump and housing.
