Thrust and efficiency
To make it more complicated; what determines the effect of the engine on a boat is not so much the power input in kW or shaft power in hp, but the thrust. So, what force does the propeller, turning in the water, deliver to the boat? An electric motor has fewer losses, partly due to the higher torque over the entire speed range. This means that a larger, more efficient propeller can be mounted, which provides a higher amount of thrust.
