The 4.0 in the Cruise 4.0's name refers to the power input. It is a 4 KW motor. Since by definition, 1 HP = 746 watts, the Cruise 4.0 is a 5.3 HP motor. The preceding is fact. The following is opinion. The Cruise 4.0's efficiency is better than most so it feels stronger.

It will feel like you have more power because it has more thrust out of the gate, but an electric motor with a max of 4hp (assuming same gearing and prop) will not ultimately push a boat any faster than a gas 4hp engine.
