I agree – but with inboards and inboard/outboards, you can’t shut the vent on the gas tank when not in use, so humidity gets in and the ethanol will combine with humidity in the air on the surface of the gas. With temperature swings expanding/contracting the air, more air with humidity is sucked in and expelled every 24 hours – take this over a winter storage season up north and it can be a problem. Same for collector cars that have vented tanks built before gas tank vents went away when vapor recovery canisters were added – tanks were vented until sometime in the 1970s. Small engine tanks for most engines other than outboards are vented all the time too. A friend paid $80 a couple years ago when his snowblower wouldn’t start after all summer. The shop told him it was likely from humidity and ethanol – it had the phase change at the bottom of the tank.
