Outboard gas consumption ?

bigdog · 07-26-2013, 08:48 AM

Trying to determine the GPH consumption for my outboard.
90HP 2 stroke. (4 carbs).

Does any one know of a link where I could get accurate information about this.

From what I've been able to find out, the general rule is to divide the actual horsepower by 10. This formula would be used for GPH at WOT (wide open throttle). So at 1/2-3/4 throttle much less would be used, maybe cut in half ?

Any feedback is appreciated!
