I have a '85 OMC Seadrive OB. 2.6ltr.,235Hp. with 2 hydraulic cylinders that tilt and trim the motor. Intial problem was a leaking fluid line, but after I replaced both flex lines on the unit(It actually has 4 lines, 2 for each cylinder) then filled the resevior, and tried to cycle the system, and bleed off the air pressure, I can not seem to get all the air out or not enough fluid. NEED HELP for one of you sharpies out there that might have experience with this old girl. Motor runs great, just can't trim her. Thanks in advance... Dave B.
