Boat propulsion device
A boat propulsion device includes an engine, a first bracket, and a first electric component. The engine includes a crankshaft extending in an up-and-down direction. The first bracket is fixed to the engine. The first electric component is attached to the first bracket. The first bracket includes a first support portion and a second support portion. The first support portion includes a first lateral surface and a second lateral surface. The first electric component is attached to the first lateral surface. The second lateral surface is arranged opposite to the first lateral surface. The second support portion is connected to the second lateral surface in a position spaced away from both ends of the second lateral surface in a top view. The second support portion includes a first coupling portion coupled to the engine.
1. A boat propulsion device comprising:
an engine including a crankshaft extending in an up-and-down direction;

the second lateral surface includes a first region and a second region with respect to the second support portion in the top view;
a reference line perpendicular to the first region passes through the crankshaft; and
the second electric component is disposed between the second region and the engine.
5. The boat propulsion device according to claim 1 , wherein the first support portion includes a plurality of ribs on at least one of the first lateral surface and the second lateral surface.
6. The boat propulsion device according to claim 5 , wherein the first support portion is a plate-shaped member extending in a horizontal or substantially horizontal direction perpendicular or substantially perpendicular to the up-and-down direction; and
the plurality of ribs extend in the horizontal or substantially horizontal direction.
7. The boat propulsion device according to claim 1 , further comprising:
a fixing member configured to fix the first electric component to the first lateral surface; wherein
the fixing member includes a leaf spring configured to urge the first electric component toward the first lateral surface.
8. The boat propulsion device according to claim 7 , wherein the first support portion includes a first recessed portion and a second recessed portion, and the first and second recessed portions are located on both sides of the first electric component in a plan view of the first lateral surface;
