The gas gauge in my 202BR is highly inaccurate. It does not move off of full until 20 gallons of gas have been used. After that it bounces between 1/4 and 1/2 on the gauge. Is there a way to free up the sensor or do I need a new one? Advise Please.

Thanks, Brent

Brent,

It's very common for a boats gas gauge to be inaccurate. The arm of the fuel sending unit in gas tank can be bent upward a little to resolve the problem of reading full until a significant amount of gas has been used. To access the sending unit, raise the sunpad/engine cover, tip the entire bench seat forward by pulling up/forward on the seat back cushion support board. The seat is hinged along the front edge and will rest on the grab handles on the sides of the boat. Removing the round cover under the bench seat will allow access to the mounting screws of the fuel sending unit. Make sure all potential sources of sparks are eliminated and adequate ventilation before starting the job. Also make sure the sending unit is 100% sealed when finished, as gas fumes can cause other problems.

Phil's right.  Mine's useless, so I'm going to replace with a fuel flow monitor over the winter I hope.

 Thanks for the advice. I will give that a try.

I've had issues with my gauge as well.   You mention a fuel flow monitor - can you tell a little about that and how it works?  Is it hard to install?  Spendy?

Brent, when you think about where the fuel sending unit is mounted on the tank, toward the transom, it helps explain whey they all act that way.  While you're cruising, the bow is up and the fuel stays toward the back of the tank, giving a false sense of being able to run a long time w/o burning any gas.  Mine will stay full for hours until I start to come off plane or punch it real good, then I'll see some needle movement.  My guage is very accurate as long as I come off plane to see where the true fuel level is.  The arm can be bent a little to help give a more accurate reading but remember, with the fuel resting at the back of the tank, it's still going to show full for a long time.
