What RPM should a boat run at?

The full-throttle limit for modern marine gasoline motors ranges from 4800 to 6000 rpm. (By comparison, your car’s engine probably turns less than 2500 rpm at freeway speeds.) Most mechanics and engineers suggest the best cruising speeds are achieved at 3400 and 3800 rpm respectively.

Should you run a boat at full throttle?

As long as you are propped correctly and can hit the upper end of the RPM range, [to run an engine at its maximum throttle all the time] is not a problem. Most smaller engines have two speeds, OFF and WOT. Very rarely does an engine wear out. Keep up with maintenance and you will be fine.

How do you calculate fuel consumption from horsepower?

Simple MethodFormula To Estimate Maximum Engine Fuel Consumption. Gallon Per Hour (GPH) = (specific fuel consumption x HP)/Fuel Specific Weight. … 300-hp Diesel Engine Example. GPH = (0.4 x 300)/ 7.2 = 105/7.2 = 16.6 GPH.300-hp Gasoline Engine Example. GPH = (0.50 x 300)/ 6.1 = 150/6.1 = 24.5 GPH.Other Related Resources:

Raising the motor one hole will most likely increase the rpm’s by a couple hundred, you should gain in top speed as well.

Why are boats so fuel inefficient?

Your boat is inefficient because you are trying to exceed “hull speed” and the power needed to get the boat up on step and keep it there is enormous.
