Abstract
An outboard motor includes an outboard motor body that, when located in a full trim-in position, an upper connecting pin is located in a lower limit position below a tilt shaft. When the outboard motor body is in a full tilt-up position, the upper connecting pin is located in the upper limit position above the tilt shaft. The upper connecting pin rotates around the tilt shaft at a first rotation angle from the lower limit position to a horizontal position at the same height as the tilt shaft. The upper connecting pin rotates at a second rotation angle around the tilt shaft from the horizontal position to the upper limit position. The second rotation angle is larger than the first rotation angle.
Claims10
An outboard motor comprising:
- a bracket attached to a boat;
- an outboard motor body supported by the bracket;
- a tilt shaft that rotatably connects the outboard motor body to the bracket;
- a tilt cylinder including an upper connector and a lower connector, the tilt cylinder being configured to rotate the outboard motor body around the tilt shaft between a full tilt-up position and a full trim-in position by expanding and contracting;
- a lower connecting pin that connects the lower connector to the bracket;
- and
- an upper connecting pin that connects the upper connector to the outboard motor body;
- wherein
- the upper connecting pin is located at a lower limit position below the tilt shaft when the outboard motor body is located at the full trim-in position;
- the upper connecting pin is located at an upper limit position above the tilt shaft when the outboard motor body is located at the full tilt-up position;
- the upper connecting pin is configured to rotate from the lower limit position to a horizontal position at a same height as the tilt shaft at a first rotation angle around the tilt shaft;
- the upper connecting pin is configured to rotate from the horizontal position to the upper limit position around the tilt shaft at a second rotation angle;
- and
- the second rotation angle is larger than the first rotation angle.
