Fuel Additive / Cleaner

[TheCabralFamily]

Hello Again, with a few seadoo's to play with over the summer, I'm trying to avoid carb & fuel injector issues along with fuel lines. All have been rebuilt or replaced just wanted to see if there was a tried & true additive for the fuel to help keep these systems clean. Looking at the posts seafoam is out, so is there a better alternative.....for 2 & 4 strokes

MAIN ISSUE, keep the damned ethanol fuel out of them! I do use an octane boost since the 215HP engine requires "premium" and my local marina only has regular.

Do not use any "cleaning" additives as it is not needed and can do much more harm than good.
The only thing you should add is some Marine Sta-bil if they are going to be sitting since the new fuels degrade much faster than older fuel did.
