I ran out of gas on the lake early this year because my gauge is in accurate but in the other direction. It showed about 2/3 of a tank and we were going for a quick after work trip so I just put 30 bucks in to be safe or so I though. A couple people ride and in the middle of my run the boat sputters and shuts off. I'm thinking the fuel pump is toast cause it showed those same symptoms and the gauge showed over half a tank. I take that Friday off work to pull the boat up to the shop, the guys take a look at a few things and then knock on the tank an what do you know it's bone dry. I go down and put some gas in and it fires right up. Idk if this can be calibrated in the vision system but in the mean time I just fill up everytime out.
