I have a 2007 F250TXR. I am having issues with the fuel gage. With boat sitting in my driveway on level ground the gage reads full. It has been an issue since I purchased the boat (March-2008). I decide to fill tank today just to see how much fuel was in the tank. It took 52 gallons. Tank is 100 gallons. I read the manual and it shows dipswitches..Any thoughts before it goes back to the dealer??

take it back.
it could be as simple as an inccorect sender seletion at the dip switches or the fuel sender in the tank is not correctly set up.
if its a fuel sender yamha wont cover it as they did not make it.
that will be a hull warrenty issue.
