How low is too low for fuel gauge reading? (2021 252XE)

[gthorson]

Second day on the water this year. I didn't add fuel cause I wanted to get rid of the old fuel from last year. I didn't realize how low it was until I was on the water. Sitting level in the water the gauge read 9%. Under way it was at 25%. When I was in the front retrieving the anchor it was at 1%. I spent the day fishing and being conservative with how far we went. Everything worked out OK but we didn't joy ride as much as the kids would have liked.

How close was I to swimming back? Anyone gone full Kramer and pushed it further?

I use the fuel used tan in the connext screen. For me it’s been accurate to 1/10th of a gallon.

Fill your tank fully but don’t overflow it. Re set the fuel used gauge, burn a half tank or so then re fuel and see how close the fuel used measures up to how much the pump says just to verify accuracy. The re set the fuel used tab again. Then you will accurately know how much fuel is left in your tank.

I purposely ran my boat really low once, but I also have the trolling motor to get me in, I think the % gauge was reading 1 or 2%, when I tied up to the dock the starboard engine died so I used the port engine to put the boat on the trailer. Once off the water the starboard engine started again. When I filled up the tank took almost 53 gallons to fill a 52 gallon tank, the overage was the fuel in the fill line. Point being I think my boat at least is designed to be able to use almost all of the fuel in the tank.

I’d say you were a ways from having to swim.

Again, the fuel used gauge has always been very accurate for me.
