Hey guys, I could sure use your advice. The Bible says there is safety in a multitude of counsel. So, please give me some counsel.

I have never owned a boat before that had a built in gas tank, but my new Crestliner has a 21 gallon tank. The owner's manual says to fill the tank each time you use it. Supposedly, according to the owner's manual, a full tank cuts down on condensation and thereby cuts down on moisture in the tank, which is one of the things that causes the "new" gas break down.

I would think that by leaving most of the gas in the tank and adding just a few gallons each time, the gas would begin to get old and then start break down which would cause problems anyway. My thinking says run most of the gas out and fill up with fresh gas, but this, according to the manufacturer, would allow condensation to start forming.

What are ya'll thoughts on this? What do ya'll normally do? Fill up each time or run most of it out and then fill up? Any advice will be appreciated. Thanks!
