Twin 4.3 Merc - Starboard engine auto trims after running full throttle

[Jay5020]

After throttling, the starboard engine automatically trims up when placing the boat in neutral. Wiring in the throttle casing seems to be fine. Seems to be getting worse, as last night while trying to diagnose the issue, I used the trim button and it kicked the boat in reverse.......Crazy sounding I know but it did. Any thoughts??

Welcome aboard.

We need to know which dual 4.3 setup you have and how old. Sounds like the boat is newer and maybe drive by wire.
