Pump out at End of Season?
I was told to keep the fuel topped off before putting decommissioning the boat for the winter. I also add a small amount of fuel additive to minimize bug growth. The only time to pump your tank is if you have a junk in it (I have been told). Use clean fuel and this shouldn't be much of an issue.
My tank holds 20 gallons. I fill it up before the end of the season. In the spring when I relaunch, I use until it reaches half full and then refill over 2X with 5 gallon each. I get my diesel from a truck stop that has a lot of traffic so I know the fuel is turned over frequently. I don't separate the fuel from water before I put it in the boat. My assumption is if it has that much water in it, trucks can't use it also and there would be an corrective action at the particular fuel stop I use. I do have a water separator/fuel filter in-line before the engine.
