In-Depth Guide & Mathematical Methodology
⚓ Marine Fuel Consumption Rule of Thumb
Gasoline Engines: Burn approx 1 Gallon per Hour (GPH) for every 10 HP at Wide Open Throttle (WOT).
Diesel Engines: Burn approx 1 Gallon per Hour (GPH) for every 20 HP at WOT (roughly twice as fuel efficient).
Rule of Thirds: 1/3 out, 1/3 back, 1/3 reserve.
Frequently Asked Questions (FAQ)
What is the Boat & Yacht Marine Fuel Consumption Calculator (GPH & Fuel Range) and how does it work?
Marine engineering and recreational/charter boating tool. Applies standard marine fuel consumption rule (10% of engine HP at wide open throttle WOT).
How do I use this Boat & Yacht Marine Fuel Consumption Calculator (GPH & Fuel Range)?
Enter Total Marine Engine Horsepower (HP, e.g. 250 HP outboard or inboard). Enter Cruise Throttle Setting (% WOT, e.g. 75% cruising speed). Enter Marine Trip Duration (hours, e.g. 4 hours). Enter Marine Fuel Price ($/gallon, e.g. $4.50/gallon). View Estimated Gallons Per Hour (GPH), Total Gallons Consumed, and Marine Trip Cost.
What mathematical formula is used in this calculation?
WOT_GPH = HP / 10. Cruise_GPH = WOT_GPH * (ThrottlePercent / 100). TotalGallons = Cruise_GPH * Hours. TotalCost = TotalGallons * FuelPrice.
