I have a 140 Suzuki four stroke. When I go to pull the boat out of the
shed, the engine will not trim up.

This happens frequently, usually only when moving the boat out of the shed.

When I press the down button, it works fine. When I press the up, it only
clicks once and then nothing.

I did notice the last time this happened, if I would quickly move the switch
up and down, it started working. This only happend once, so I don't know if
it did anything or it just decided to work when I tried it....

Anyone have a clue as to what's causing this?
