Don't know about this one...my trim on my Gen II works intermittently. Sometimes when I actuate my up or down switch the FIRST time the outdrive moves, most times it doesn't move the FIRST time. I don't know about this one. A "Mechanic" put a new switch on the boat for me (located remotely on the instrument panel) and the trim works the same with that one...not good. Some times it takes a lot of coaching (Translated: moving the switch up and down a LOT) to make something move in the back. HELP.
