Thanks guys. Big.. That was very informative.. The rubber strips is where the corroion was ..where it was not adhered pperly so thats where it trapped water an started corroding..but that was very interesting about rubber itself.. I have had the bilge wet up to tank with all this rain we have been getting.so i moved th boat under the boathouse. I agree alum is one of the best materails made.. I will have the tank repaired. My coworker buileds race car role cages for rodders .. Will probaly use the two70 gallon tanks cut the forward box out and put in the stern for storage.. Thanks for the info..

Sandy,

Good points all.

E10 is a bitch and interjects a whole new dimension into the thought process. I've always stored my tanks full, but e10 challenges my reasons for doing so. My thoughts are now about have a CO2 fire extinguisher rigged into the tanks to expel any ambient air and its humidity. Its heavier than normal air so in should not be dislodged.

Yeah Rec90 is the way to go, however looks like we are stuck with ethanol for a long time!! Check out this 4 minute video to really get you puckered up!!!
