Just bought boat with 150 evinrude xp. It's an 89 engine as well as hull.
It originially came with a 150 Merc and someone changed motors. How
would you go about wiring the tac up correctly. I suspect it is not wired
at all, but would like to know how to do so, and hopefully it's not the
guage. thanks
