How many hours will the engine typically run on one tank of fuel, depending on conditions?

• A. 1-2
• B. 3-4
• C. 4-5
• D. 2-3

Answer: (D)

Fuel endurance per tank depends on how much fuel the engine uses (burn rate) relative to the tank’s capacity, and that burn rate changes with speed, load, and conditions. For a typical boat and standard tank, you’ll usually get about two to three hours of running time. Cruising at a moderate speed with a light load and good conditions tends to tilt toward the upper end, closer to three hours. Pushing into high-speed planing, carrying heavy gear, towing, or sailing in rough seas will increase fuel consumption and shorten run time toward around two hours. The other ranges would generally require either a much larger or smaller tank or unusually high or low fuel efficiency, which isn’t the common scenario for everyday use.
