Where do I start troubleshooting my electric trim system?
Nothing happens when I use the Up trim switch - no sound, no movement. The
trailer (up) switch works correctly. The Down switch lowers the motor, but
not the last couple of inches. I pushed it down with my boat pole to get it
all the way down.
Once underway, I could use the Trailer switch to trim up and the Down switch
worked correctly.
The boat sat in dry storage for seven months. It took about a minute to get
the gas pumped back into the carburetor, but then it started right up and
ran great. This trim problem is the only thing not working.

The sensor that detects actual trim limit could be defective or
disconnected or have a bad connection. I'm told that those hockey puck
shaped switches that are mounted at the end of the outdrive pivot shaft,
are prone to failure.
