I have used 100LL (avgas) when laying the boat up. It has a long shelf life and is a good plan. This E10 (ten percent ethanol) is really hard on boat engines. The shelf life is almost non-existent. There have been all kinds of problems. I think the marinas here are selling E10. I think that is all that is available. I hear that Stabil will not work and there are some new additives. We could get real 100% gas until just recently. jim
