I learned an expensive lesson on a Yamaha Outboard years ago running ethanol, replacing the carb's @ $1,600 for the stack. That junk will also ruin your lawn mowers and weed eatersI try to put in non-ethanol but have mixed gas before it’s a Yamaha it just runs And runs and runs.
I agree, for older carburated boats, especially older 2-strokes, the E10 can be problematic.I try to put in non-ethanol but have mixed gas before it’s a Yamaha it just runs And runs and runs.
Exactly the point. Avoid the ethanol if possible when storing for long periods of time. But the old stories of ethanol damage on a daily basis is not an issue anymore. With the amount of gas we burn weekly, there is no time for separation issues either. Yamaha and most MFG's addressed the issues of Ethanol in EFI engines for regular use years ago. They knew avoiding ethanol is just not possible in most situations, so you may as well make them handle it.I agree, for older carburated boats, especially older 2-strokes, the E10 can be problematic.
In all new Yamahas that is just not the case. The plastics, seals, and all surfaces in contact with fuel are fine with E10, just like a new car or truck. The new fuel systems handle E10 perfectly, there is zero issues. Stabil or similar for storage.
Would I buy non-ethanol fuel if I have access? I do every time. But there is simply nothing wrong with E10 in these new boats.
