I bought a 2008 20x2 in May of this year. When I first got it, the gas gauge seemed to work ok, but showed more gas than what was really in the tank. But it moved up and down with filling/using fuel. Now after filling it the last time, it’s stuck on full all the time. Even when the boat is powered off, the needles stays on F and I thought when it worked properly, it went to E when shut off and upon turning the key it would jump up to the correct position.
Any tips on where to look to start troubleshooting this?
