I have a 1999 fitch and where my trim relay connects to my pdp the is a burnt spot where one of the relay prongs goes in. Trim want work. Brand new relay. I can push the relay to the side and it will tilt and trim. I'm thinking I may have a break in the wire. Also my check engine alarm started going off and my boat would run rough when put in gear and sometimes shut off but runs great on plane.Thinking it may be a throttle position sensor. What do you guys think?
