Hello all, I have a late 80's U.S. Marine 125 force motor, with tilt and trim. Went to do spring checks before putting in water and hit button to trim and nothing. heard the click of it trying, waited a while and tried again worked with no problem. Then this morning did same thing. What could be causing this?
Battery fully charged.

I assume its a hydraulic system. Did you check the fluid?

yes and it is full. Tapped on the motor housing of the pump and worked fine. I think the motor needs to be cleaned or rebuilt.

what are your thoughts
