Re: my first boat!!! (and a question)
Hey Rat, welcome to IBoats.
Generally speaking...when gauges start doing funny stuff it is a "Ground" problem. Make sure all of your gauges have a good clean ground. Don't just look at them...pull the terminal lugs off and clean them. Then check the other end where the ground source is...batt, fuse block, spice area etc...
Then go to the trim pump and do the same thing to it's grounds.
This usually works for me.
Hope this helps.
