Water in the fuel tank.

Spoke with a mechanic and he suggested to keep treating the gas with the additive, and draining the clear glass bowl when needed. My 2 stroke engine isn't as susceptible to a tiny amount of water as the newer 4 strokes or HPDI engines. Honestly....I don't like it, but until I notice some hesitation or sputtering from the engine, it's what I'll try. Having BoatUS is some insurance as well. Any signs of rough running and I'll shut it down, toss the anchor, make the call....and have a beer!
