Re: 1987 Mercury 70hp "power trim" not working
Hey puckoach,
Let me preface this by saying that I ask a LOT more questions than I can answer.
When I first got into my boat this spring I experienced the same type of issue. When I first tried to tilt my motor all the motor would do would 'click'. I knew my battery was good as I just bought it last fall and kept it inside through the harsh winter.
In my case, since it was so cold for so long this winter,(I'm near St. Louis) the fluid in the cylinders had become so viscous that the t/t motor couldn't move the outboard.
What I did was release the manual knob on the tilt motor and I manually lifted and lowered the the outboard to clear the cylinders and the lines. It was difficult at first, but became easier the more I lifted and lowered it.
Then I refilled the tilt reservoir, bled the system, and topped off the tank. Have not had one issue since then.
