Is it best to drain fuel tanks and outboard of gasoline or leave them full? I have a mercury 90, 2 stroke with aluminum fuel tanks under seat.
Thanks

With portable tanks, I would drain them completely.

I drain my carbs and the fuel tank. Ethanol absorbs water like a sponge, and evaporates leaving the H2O in your tank. Which is worse, the condensation from an empty tank or water absorbed by the alcohol?
