Hey guys, just recently bought a (new to me) boat. The power trim unit was leaking out the top of the cylinder around the ram wiper seal. Bought the $70 O-ring kit, took it apart and replaced all the seals and O-rings in the cylinder. Did not replace or touch anything in the other side. I did as well replace the motor on the unit. The cylinder on the inside looked clean and free of any scoring or anything. Put it back together and added fluid till it starting going up and down. Well ive taken it in the water twice since and noticed when I trim my motor to get my max RPMs, the motor slowly trims back down on its own. I basically have to keep trimming up every few seconds to stay at my max RPMs when running WOT. Is it a possibility that I haven't put enough fluid back in the system? I do hear a little "bubbling" when I trim up so I'm assuming there is still air in there even though it should be self bled. How do I know when my system is full? thanks in advance!
