The topic of E15 has been brought up several times over last few months.

MerCruiser has a bulletin (2010-16) that specifically states that E15 fuel is considered misuse of the engine and resulting damage will not be covered under warrantly. Merc's preference is to use ethanol-free gas wherever possible. Merc's engines are designed to use fuel containing up to 10% ethanol content. The bulletin further states that the EPA waiver allows E15 to be used in newer light trucks and cars. However, EPA regs do not allow E15 fuel to be used in Merc's engines.
 
FWIW in South Carolina, I can still purchase and do purchase ethanol free gas at marinas and a couple of land based gas stations.
 
This ultimately will make all trailer boats forced to purchase gas at marinas to get the lower E10...

or find engines that can burn E-15 or E-25 (which is in the future)...
 
Fortunately, we are not seeing any e10 in West Michigan marinas. We did not run into any e10 from Holland to Harbor Springs. When we go to Wisconsin we fill up on this side of the lake and fill up again when we return to Michigan.
 
The pump used to dispense E15 is called a blender pump. It mixes regular unleaded with a ratio of ethanol. These pumps can someday also blend higher ratios of ethanol to unleaded fuels as the EPA approves its use. These blender pumps aren't cheap for the retailer. I doubt you will see much, if any E15 on the water anytime soon. There are fines to retailers for selling E15 to a consumer that is filling his pre 2007 auto. I'm not certain the marine industry is ready for a gas attendant to ask "What year is your boat sir? OR "Would you like the yellow or black hose sir"?

I'm thankful my marina only has regular unleaded on tap.
 
The problem with ethanol is no control over actual input. Know what happens if you have a blender pump add ethanol to fuel the truck driver added ethanol to; which BTW the storage facility added to the already ethanol laced from the refiner?

Ask a BUNCH of Virginians whose engines went poof and whose insurance companies said tough shat.

There is NO WAY congress should be allowed to delegate the authority to make or enforce law. WTF?
