My trim and tilt hadnt been working, the PT/T motor was running but no action. i figured it needed fluid. So i put something in it... I just realiazed thinking about it right now, that i put gear lube in it instead of the brake fluid i bought at the store specifically for this. So i filled it up with the gear lube and it began to function again but then sprang a leak from the top of the cylinder where the piston/ram comes in/goes out. Could the gear lube have done this or did it just have a bad seal from the get go. The motor's a VJ50TLETB and i bought it non-functioning so i've actually never used the trim/tilt till now, or the motor for that matter. I plan on flushing the system tomorrow, but is rebuilding that cylinder a common procedure, or is the unit replaced more often than not. I'm thinking im going to shop it once i can mount it on my toon, it needs a link n synch too, new prop and new timer base. But is DOT3 brake fluid acceptable for PT/T, or is there a heavier hydrolic fluid that suits it better. And does anyone know what an acceptable shop bill would be for a link n synch, and whatever trim/tilt option is the least expensive fix (buying a new vs rebuild).
