Re: Force trim won't go up!
Follow the wires from the trim pump, up into the cowling.<br />There should be two relays plugged into a wiring harness.<br />One for up, the other for down.<br /><br />Unplug them and swap positions. If it is a relay, the problem should now be reversed. That is, it will go up but now down.<br /><br />You can get a replacement relay from Merc for $13, or try a NAPA parts store.
