Trim does not work

[Greg Morris]

I have a 1985 thundercraft I/O. When I try to raise the trim all I get is a clicking sound. I have done continuity checks on the 50 amp fuses and they all check good. Any suggestions on what I should check next?

So, what does a 1985 thundercraft I/O have for power and drive? Mercruiser, Volvo, OMC????

I replaced a trim tab motor in my 19 ft fishing boat that was doing the same clicking trip.<br />It took awhile for me to find the nerve to do it, but after looking inside the motor, I knew the poor thing had lifted it's last ounce of fluid. The motor commutator was totally gone as was one of the brushes.

I replaced the solenoids on my 74 and it stopped the clicking problem.<br />Also, check for poor connections.
