How thirsty are these compared to a carbed version?

these are better on fuel than carb'd engines...

fuel consumption depends on how the boat is propped-prop it wrong,it'sgonna suck fuel like a jet,and you'r gonna detonate the engine...
prop the boat to run at the top rpm-with a full load

10% rule-use this for 2stroke carb'd engines-meaning-250hp-10% is 25-that's about what this engine is gonna burn for fuel @ full throttle,figure aprox 50% less @ cruise speed-again depending on propping correctly-10-12gph...this is for carb'd engines-again,fuel injected engines are gonna be a little better...
