Hi and thakns for reading. I have a pair of Yamaha SW Series II 1997 150's. On a recent raod trip, I forgot to turn off the power, the right enegine trim switch somehow got stuck in the "UP" postion for about and Hr. We stopped for gas in the tow vehicle and I heard the tilt/trim motor running LOUDLY. I managed to get the sw dis-enguage and cu off the power. Motor would not tilt up or down at that point. Got home and tried again and got motor to tilt all the way up, but would not go down at all. Ordered and installed new cowling switch today. No Change -- Goes up - motor runs but no motor when dwn swicth hit. I can hear the relay click but that's it. I checked the 20 amp and the 30 amp fuses in the motor and they seem fine. Is there another fuse somewhere?? BTW -- Tried to get the manual screw to release, but no joy. Screwdriver slot was trying to "round-off" so I stopped. Any hints or suggestions welcome --
