winterizing your boat

Hello @Goby --- yes --- I use 91 octane/NON-ethanol fuel 100% of the time (highest octane I have access to) --- I put the Ethanol Shield in the tank for my last trip or two in the fall so that the Ethanol Shield is in the tank/hoses/engine --- then when I winterize the boat I fill the tank full of 91 octane/NON-ethanol fuel and add in an appropriate amount of Ethanol Shield to the tank to help keep moisture out of the fuel/tank because here in MN the boat is "winterized" from November to April --- again, 100% of the time I use 91 octane/NON-ethanol fuel 

Roger that, I use Star Tron the same way. 

All outboard engines are designed for 87 octane fuel, while putting 91 octane in it doesn't hurt anything, if you can ever get say 87 octane recreational fuel for cheaper, don't spend more for 91 octane. 

It's hard to find 87 octane recreational fuel in Michigan, usually 89-91...

Tennessee had 87 octane rec fuel when I was there a couple weeks ago fishing...
