Hello I am having a trim problem with my boat, I can trim my boat up with the trailer switch and the transom switch but not on my throttle, however I can lower the trim on my throttle. I moved the trim sensor thing on the outdrive but that dident do anything. Maybe a bad switch? Can anybody help me out?

i posted the exact same thing, ended up you must have the killswitch on and key on for trim on throttle to put the drive up, and it will only go up so far then you use the trailer button, i thought i was nuts when i realized it was such a bonehead fix!
