I recently was having problems with my 2003 Polaris PWC. I took it in, and the marina said that I had high ethanol gas in the system and it completely warped my fuel pump. $800 later, they said to try to buy pure gasoline (no ethanol). The marina said this is becoming a huge problem - especiall in boats older than 10 years. I have a 2006 Outback LSV. I plan on running the pure gasoline from now own, but does anyone know if the tank and other components in this boat were made with materials resistant to ethanol gas? I am concerned, because I am sure I have fuel in my boat from the same station. Probably not purchased at the same time, but definately from the same station. I hope the tank and other plastic components do not start deterioating.
