For which boat? The hot rod formula?

No idea on fuel consumption. I filled that b*tch up with premium and let her eat. Would run deep into the upper 80s on GPS at around 5.5k Cruise around 50 at 3.75k.

New boat will almost touch 60 on the GPS laid wide open and cruises comfortably around 40. No ideas on RPM, don't really pay much attention to the egg beaters. I fill it up with cheap gasoline and good 2 stroke oil. It goes an insane amount of time on 50 gallons. Hot rod boat could eat through a full tank no problem in a day.
