40hp 4 stroke efi 3cyl. recomended plug Champion RA8HC

I Troll a lot at around 2mph, should I switch to a different plug? What would be recomended?
 
I would leave the recommended spark plug. Be sure to use non-oxygenated fuel. Why? Ethanol produces nearly 5 percent less power....and it's shelf life is about 1/10th that of pure petrol.....it's very hydroscopic, (absorbs water).
 
Thanks, I would love to use non ethanol fuel but I can't find any in my area. Do you recomend something I could add to the fuel to help?
 
Thanks, Chris.
Nothing eliminates the ethanol. Where are you living?
