The embodiment of the invention discloses a marine propulsion device based on heat effect resistance reduction. The marine propulsion device comprises a heat source, a water pipe and a shell. The water pipe is partially arranged in the heat dissipation area of the heat source and is provided with a water inlet and a first water outlet; the shell is provided with a water contact surface in contact with water, and the water contact surface is provided with a second water outlet; the water pipe is at least partially located on the inner side of the shell, and the first water outlet communicates with the second water outlet. The water pipe is arranged in the heat dissipation area of the heat source, and water in the water pipe can absorb heat of the heat source in the process of flowing from the water inlet to the first water outlet, so that the water in the water pipe is heated. Meanwhile, the heated water can heat the water contact surface on the outer side of the shell, so that the Leidenfrost effect is genera
