Nortech? I saw it when I pulled into my storeage one day. It looked like the owner was fixing the trailer brakes . . . I waited around for a while, but I never saw anyone
Pretty sure that they're gas

Could be but when I keep my boat on a lift I had to get 89 because thats what was on the water and would get soot like that. Now that I trailer I use 87 and no more soot.

Yes.....When I first got my boat with HP500EFI's I figured I would use the best gas.....the highest octane. My transom looked like that at the end of the day. Use the right octane and it won't look like that at all. But if they have superchargers....rich is better than not!
