Further, by removing the bracket, it is possible to access the engine body and the starter motor without removing the first electrical components individually, so that maintainability can be improved.

In the marine propulsion device according to the first aspect, preferably, the bracket is arranged so that the upper end of the bracket is lower than the upper end of the starter motor. If comprised in this way, it will suppress that the cowling of an outboard motor becomes square in the part corresponding to the upper end of a bracket resulting from the upper end of a bracket projecting upwards rather than the upper end of a starter motor. Can do.

In this case, preferably, the first electrical component is held by the first electrical component mounting portion of the bracket so that the upper end portion of the first electrical component is lower than the upper end of the bracket. If comprised in this way, since the 1st electrical component arrange | positioned at the hull side of a starter motor is arrange | positioned in a low position, unlike the case where a 1st electrical component is arrange | positioned in a high position, the cowling of an outboard motor It can suppress that the shape of the part by the side of a hull becomes square.
