What's the approx. fuel burn with 150 hp ?

There are several ways you can do this. Conditions odviously make a difference. But, everyone wants to know how far can I go on a gallon of gas. I went out of ponce inlet a few days ago with my wife and two kids. I had exactly one gallon of gas in a milk jug, unplugged the fuel line from the engine stuck into the jug and took off. I reset my Chart plotter brought it up on plane like I normally would. Trim the engine and settled in at 3500rpm. Which is about 28 mph. and watched the fuel filled milk jug empty at a alarming rate. It's interesting to see how much fuel these old two strokes burn especially when you can actually see the fuel level drop. It gave the kids an idea of how expensive it really is to go tubing :)

The results were in:
Boat: 1978 V20 Cuddy
Engine: 1987 150 Suzuki Super Six
Load: About 25 gallons of fuel on board two adults and two kids 12 and 9
Sea Conditions: 1' (calm)
RPM. 3500
Speed: 28 mph
Gas mileage: 3.04 miles per gallon
Not to shabby for an old 2 stroke
