Can anyone help? I have a 75 yamaha with power trim. The pump and motor and all the internals seem to work, only sometimes all I get is a clicking noise on the solenoid. A light tap on the pump triggers it to work again, (I have had it start working again by tapping on the motor as well) only to have it hang up again. It is a dual piston and single ram, I guess that's how to describe it. Thanks<br />Arthur
