I have a 2000 225 Merc. EFI. The power trim to tilt the motor up on the engine is not working, but it will tilt down. I can tilt the motor up using the tilt/trim on the trottle and at the bow. Any suggestions? I took the motor cover off and nothing seems to be disconnected from the rocker switch on the motor. I HATE electrical problems, seems the only way I can fix anything is by completely redoing it, and I only know at that time whether that was what the problem was....because now it will either work or still not work.
