(IMPORTANT NOTICE ABOUT GAS MIXED WITH ETHANOL)
There are new concerns about gas mixed with ethanol and its effects on
fiberglass tanks.
This was quoted from BOATUS.
Soon after the Long Island Sound area of New York switched to gas mixed
with ethanol, BoatU.S. began receiving calls from boaters who owned
older gas-powered boats with fiberglass fuel tanks. The tanks, it
seemed, were being slowly dissolved by ethanol; black stuff was building
up on valves and intakes, destroying engines and some fuel tanks were
becoming soft and even weeping fuel.
What can an owner of a gas-powered boat with fiberglass tanks do? There
doesn’t appear to be any quick fixes or magic additives that can slow
the degradation of fiberglass tanks. Tank replacement is the only sure
cure. In the meantime, owners of these boats are urged to install
gasoline vapor alarms.
