We had a Frog Floater come through this week; the A got caught in it; ran through some high water. She said it started missing; and finally died. Drug her home; did some checking: oil still clean; transmission is sealed. I'm guessing water in gas. Noticed engine is dry;no water marks anywhere under hood. (Also noticed there is no fan blade! Is it suppose to have one? It is water cooled!). Can replace the fuel filter; but would disconnecting the gas line from the tank and turning on the key drain the tank?
