OUTBOARD GAS CONSUMPTION
For years, we computed outboard gas consumption easily. While there were a few differences, most outboards burned gas according to the following formula: Gas consumption per hour= horsepower/10 

But nowadays, there is great difference among motors. Some brands of 2 cycle engines burn fuel by the formula:Gas consumption per hour= horsepower/12Four cycle engines are now boasting of even better gas consumption. Many burn gas according to the formula:
Gas consumption per hour= horsepower/15.
Using the above formula of:
Gas consumption per hour= horsepower/15,
how much gasoline would an engine burn with the following horsepower and given time of operation?
a 40 ph for 4 hours?
A 25 hp for 3 hours?
A 90 hp for 6 hours?
A 6 hp for 9 hours?Write the formula for your family's outboard motor gas consumption.
In each case we assume that the engine is being run full throttle.
