You know, as I’m doing a little more research, you may actually be able to use leaded fuel as long as you’re running in the ocean and not a reservoir system... If that’s the case, I’d probably look at mixing 25% C12 with pump 93 octane. I’d still avoid avgas, as you’re not going to want to run it straight like you would have to in order to get to 96. “Low Lead” is 1.2-2g per gallon of gas, which is two to three times the amount that used to be in pump gas.
