What makes a boat fuel-efficient?

Your boat engine will run most efficiently when the boat's trimmed, roughly parallel to its at-rest waterline, and it's not leaning too far to one side or the other. If it's safe, ask your passengers to move so the weight is evenly distributed—it can make a big difference. Reduce wind drag.

How do you save fuel on a boat?

If you're not in a rush to get somewhere, then reducing your speed is one of simplest ways to ensure you're using less fuel. Keeping your boat's engine propellers in good shape is another way to save on fuel. Make sure that the engine's blades are regularly polished and checked for damage.
