Trim cylinder diagnosis

[OneFineFiftyNine]

I have a question.

I recently took the trim cylinders off my boat since the tilt/trim was not working. I was able move one trim cylinder by hand, (and squirted oil all over my car) but not the other.

My question is, should you be able to move these by hand with them completely disconnected?

I just now got a set for free for a coworker, but I cannot move these by hand either. And if you are supposed to be able to, is there a trick for freeing them up? I cannot afford new trim cylinders and am hoping to just get something to work for the summer.

I do not no what type you have ? with more info you can be guided to the correct service manual


But in general you can block one set of lines and hook up a single cylinder to the other set OFF of THE OUTDRIVE

It the PUMP is good it should move the cylinder

Thanks for the reply tommays.

It is an old Mercruiser outdrive, 1970-ish. The numbers on it have been obsured, but I am assuming it is pre-Alpha. Of course, the outdrive is sitting on my garage floor.

I will try that, the pump does run and it sounds pretty strong. Now to find a way to block of the lines, lol. I am sure I can find a fitting or two that will do the trick.

I believe you'll find that the lines on the Rams are 3/16" Brakeline Fittings.......
I maybe Off on the Size,.... But they ARE Brakeline Fittings.....

And,.....
The Pump makes Way More Pressure on the Up side, than the Down side,.......
Use that to your advantage, Regardless of Which Way the Ram needs to Move....
Reverse the lines if Necessary........
