That seems a little drastic to deal with water in the fuel?
OP - I'm guessing that you have a portable tank for your 40hp? And gas costs like "nothing" a gallon?
Your engine (if I understand correctly) has fuel injectors? I do know that certain injectors can be averse to getting water in them - not sure about yours. The water that "may have" mixed with the fuel would be bound with the alleged ethanol and thus will not drop out in the filter but continue to the injectors. If I was in your shoes, I'd just change the fuel out and make a note to use stabiliser in future.
