I think the manual says about 1.5 hours it can burn all 40 gallons at full throttle..I normally use like 15-20 gallons on a saturday..You have to figure the 2 stroke oil at 35$ a gallon as well...I probably need a small block to stay in that mileage...thx..Jason

Thanks guys...There is what you want and reality...Boats are expensive, but I don`t need a boat that sucks 100 bucks of gas in a day...I look for something with a SBC and i/o or keep the seadoo...thanks! Jason

Hey Guys, every since I was a kid I wanted a jet boat...I rode in like a 70s 80s something Tahiti with a BBC and I was hooked...I want one and I familiar with jet drive as I have a seadoo challenger 1800... I have looked at a ton of them and like a Advantage open bow with a BB for my needs...I`m a little concerned with what the fuel issue will be...The seadoo is 220 hp (2x110) strokes. I want to stay in the same ball park as far as fuel cost...Do I need a SBC or i/o to stay in that area...I don`t want to get the thing and be shocked if it just sucks gas...I understand it varies with how you drive it, but does a BBC jet drive just suck fuel? thx...Jason
