Re: 1989 Force 125 Tilt Ram Cylinder
The trim cylinder and shock are mounted on plastic bushings at the lower end. Coupled with that, the bar goes all the way through the trim unit and there are 6 webs where it corrodes in nicely. Heat will usually not help in releasing this mounting bar. I don't envy you your job--time consuming and nasty. You will need to tough it out. It is easier to spray everything with the engine off the transom. But be aware: I have had ones where I needed to cut and replace everything.
Up top, the bar goes through the yoke and the rubber bushings in the cylinders have steel inserts---another fun piece to remove.
If I remember correctly, there was a thread in this forum about the part--adapter for the hydraulic line. It cost about 45 bucks. Do not screw the fitting in too tightly: you will break the strap. And once the fitting is snugged to the cylinder, hold it with a wrench while you tighten the hydraulic compression fitting into it.
