I had an issue with my power trim while at Sardis a couple of weeks ago. It just clicked like there was a solenoid stuck and mouldn't move. Loosened the maual relief valve to lower it and was able to troll. Tried it for grins a hour into trolling and found it working. Loose wire maybe? they all seem tight.1984 Champion with Mercury 150 outboard. Dealer in MS said I need a new trim pump motor. Can it be rebuilt? Man said the motor is about $1000. One guy thought it might be from having it stored with the transom saver locking it into the same position all the time. Anybody experience this?
