I have had problems with my boat all summer! Bad relay on tilt motor, cracked cylinder. Boat ran fine a couple weeks ago, but last weekend I couldn't get it to idle. Took it back to my Excellent Mechanic and he said I had water in my gas tank.
Today, I drained the tank and the picture shows what was in the tank.
I have a plastic tank, mix my own oil & gas.
Any ideas what this stuff is and how I can avoid it in the future????
It could have gotten in with air, then been adsorbed by the ethanol. StaBil for Ethanol will help control that, but only a water separating fuel filter will keep it out of your engine.
The thing is, I put StaBil ethanol treatment every time I fuel - never go without. I pulled at least a gallon of the milky substance out of of the tank. The Mechanic, who I trust implicitly, said ethanol was most likely the culprit, but given the amount I removed, I wonder. He checked the fuel cap and said that it looks fine. The tank is empty and dry - I think I am going to just pay the premium for Ethanol free fuel.
