OK,

replaced the electric trim motor last Fall. now trims fine and quiet, as a matter of fact it trims so good it even does it on it's own!
motor trimmed all the way down, throttle fwd from idle (1/3 of the way), cruising along w/ no trim input, and away she goes.... trimming up until i hit the trim down throttle switch (thumb switch), then she'll trim normally.

the only thing i have noticed is that the thumb switch on the throttle handle feels a bit crunchy... not smooth as it should be, but not obviously a problem.
dealer is ordering me a switch. is this something I can replace with my standard tools and pretty good hands-on skills or something the dealer should tackle?

any other ideas on what could be going on? it doesn't do this sitting idle on it's own, just after advancing throttle to about 1/3 and motoring through the water.

I would be looking First at the engine trim switch for water intrusion. AND A shorted / chafed wire where the control handle pivots and rotates as the handle is moved forward. The trim wires are supposed to wrap around the inner central area of the shift handle. Too tight or no wraps have been known to chafe the wires.

Will do... thank you

May also want to run a while with the bow trim switch red wire unplugged especially if you've been fishing in the rain.

Thanks, great idea Champ... It's been in winter storage, no rain exposure yet...
