Boat fuel consumption gauge
by Alex
Expert answer:
Quick answer
A boat fuel consumption gauge displays real-time or average usage in gallons (or liters) per hour, helping captains track fuel burn and plan trips.
Detailed answer
A boat fuel consumption gauge taps into sensors on the engine’s fuel line or electronically reads data from onboard computers. It tells you how many gallons per hour (gph) you’re burning at the current throttle setting and rpm.
By watching the gauge, you can find optimal cruising speeds that maximize range. For example, a certain rpm might yield a lower gph figure, letting you travel longer on the same tank. Changing conditions—waves, wind, or cargo weight—also show up in higher or lower readings.
Some modern multifunction displays integrate this info with GPS, calculating miles per gallon (mpg) or range left. This keeps boaters confident in exploring further without running dry. Regularly cleaning the hull, maintaining the prop, and monitoring weight help keep the gauge reading stable and your fuel bill lower.
