1995 Yamaha 2 stroke 90 hp. Trim and tilt will not lift the motor. The trim motor is working in both directions but will not lift the motor. I have tried everything I can think of. I tried squeezing the fluid in under preasure while someone else works the switch and got nothing, I tried turning out the bypass screw and lifting the motor manualy and nothing, with the motor up I disconected the cylender from the motor and it goes up and down like it should but as soon as I reconect it and take the lock off the motor it drops all the way down and wont move on its own power. It is full of oil but it had none when I got it. I suspect there is an air pocket somewere but I cant get it out. Any help would be apreciated.
