87 and 89 and always with Marine Sta-Bil and sometimes I'll add Lucas fuel treatment on top of that. Never need higher octane for these N/A engines.

So I have the SVHO engine in my waverunner and looking at getting the ar195 as well. All I have around me seems to be 93 with ethanol or 90 ethanol free seems to be the highest I can find without ethanol. Would I be better of using the ethanol containing premium in this case?

Premium for boost, 87 for na. Id run non ethanol if it was at the pump and the same price, but otherwise it's e10. I've never used any stabil or other additive and never had an issue. Dozens of boats, 1000s of gallons of fuel. I bought some fuel injector cleaner, but i think it's snake oil. I pulled all my injectors and ran them and they all looked great with 400hrs. I tested one from a 20+ year old mustang and it worked perfectly too.

87 octane with marine stabil and some star tron .The big question this time of the year is to fill it up or leave it low as it sits wrapped up for the winter in freezing temperatures

I use non ethanol gas on all my engines that will sit for any length of time to include my boat, and small engines as for lawn mowers, grass cutter etc. I have found it cheaper in the long run as it does not gum up the carb etc.[flag]
