 I find that the old summer gas don't run good after a layup of 8-9 months; the engine misfires (rough and rpm drops) a little til I get to the point where the new gas is getting through. So i siphon it out and run it in my truck. I don't like misfires offshore - it's worrisom.

  Completely empty the aluminum tanks shouldn't corrode. I've had aluminum tanks corrode through, but from the outside where salt water and air was present.
