Evinrude Trim Issues

Ok, so lets go thru this step by step. You say you can hear the trim motor trying to work. What does that mean? Is the motor actually running, or do you just hear the solenoid(s) clicking in? If the motor is running (you can hear it humming/whineing) then the next step is the pump itself. Does it have fluid? If there's a bypass valve is it closed? Can you take off one of the hoses to the hydraulic cylinder to check if fluid is actually getting to/flowing to the cylinder when the pump is running? You said you and a friend lifted the engine to get the boat home... So I'm presuming from that sentence that the cylinder itself is not bound/stuck. But as a last resort I'd disconnect the cylinder rod from the engine and see if I could manually pull it open and closed. In short you want to make sure that everything is capable of working the way that it should.

So update 17 or whatever we're on now. After some tinkering around and adding more fluid I finally got things working. Mostly. The motor will trim all the way down but not all the way up. My boat has two trim rods and the main cylinder that is connected to the motor. It will only go as far up as the two trim rods will lift it. After that, nothing. I can manually lift the motor all the way, which is quite heavy, so I know that cylinder is not stuck. Thoughts?

When u lift manually,do u have to loosen the bleed screw.

Sounds like you have air trapped in your lines.
