Tilt and trim - mind of its own
I have a 90 hp 2 stroke outboard on my rib. When teh boat is on my drive I always leave the engine lowered. I lifted engine for towing to slip and lowered it when the boat was in the water. Started up engine and it lifted without touching either tilt/trim switch. Switched ingition off and lowered again and after a few seconds it raised all by itself. The only option I had was to disconnect the plug for the switch on the outboard. I was now able to use the tilt and trim from the throttle without any problem. I've had a look at the switch on the outboard and also taken it apart thinking that was the problem, it's a fairly simple switch with not much to go wrong.
Is it possible that some moisture may have got into the switch and caused the problem, or something more expensive?
