Abstract
There are included: a motor contained in a top cover; a vertical shaft that is rotationally driven by the motor, the vertical shaft being contained in an extension casing; and a propeller that is rotationally driven by the vertical shaft, the propeller being provided at a gear casing. A heat exchanging member is provided that is positioned below an anticavitation plate and above a propeller shaft that rotationally drives the propeller, and inside the heat exchanging member, a cooling oil channel member is provided that cooling oil for cooling the motor flows through.
Claims18
An outboard engine comprising:
- a motor contained in a top cover;
- a vertical shaft that is rotationally driven by the motor, the vertical shaft being contained in an extension casing;
- and
- a propeller that is rotationally driven by the vertical shaft, the propeller being provided at a gear casing;
- and
- a PCU (Power Control Unit), wherein
- a heat exchanging member is provided that is positioned below an anticavitation plate and above a propeller shaft that rotationally drives the propeller,
- a cooling oil channel member is provided inside the heat exchanging member, cooling oil flowing through the cooling oil channel member to cool the motor, and
- a cooling water channel member is provided inside the heat exchanging member, cooling water flowing through the cooling water channel member to cool the PCU.
