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?
Thanks
Mark

I had that on my outboard but it started happening 20 miles out at sea. In fact just as I was going to deploy divers. Had to have a guy sit next to the outboard and keep pressing the down option on the switch all the way back.

Was a simple mechanical failure of the switch which was replaced and never been a problem since.

Yep same here. Had a faulty switch in the remote handle.

Repalced in a few mins with no issues.

What engine and remotes do you have?

The engine is a Yamaha 90hp 2 stroke, I think it's a 1997 model.

Not sure what you mean by 'remotes'. Do you mean the tilt switch on the throttle handle? There's a switch on the throttle at the helm and one on the engine.

Mark - the "remote" merely refers to the controls remote from the engine (could be outboard or inboard start switch/ kill switch/ throttle/ trim/ tilt etc) - but it sounds like you just need a new switch for outboard end (unless it's all fine after cleaning out !).

Had a similar problem, turned out to be damaged wiring where it passes below the bottom cylinder from the cowl switch to the solenoid.
