MARINE PROPULSION DEVICE
First Claim
1. A marine propulsion device comprising:
- a motive force transmission system including a crank shaft and a drive shaft arranged to transmit a motive force from the crank shaft;
a propeller shaft arranged to transmit the motive force from the drive shaft;
a housing section that houses the motive force transmission system; and
a clutch attached between the motive force transmission system and the housing section, the clutch being arranged to permit relative rotation between the motive force transmission system and the housing section by opening a connection between the motive force transmission system and the housing section during a forward rotation of the motive force transmission system, and to prevent the relative rotation between the motive force transmission system and the housing section by closing the connection between the motive force transmission system and the housing section during a reverse rotation of the motive force transmission system.

Abstract
A marine propulsion device includes a motive force transmission system, a propeller shaft, a housing section, and a clutch. The motive force transmission system includes a crank shaft and a drive shaft which transmits a motive force from the crank shaft. The propeller shaft transmits the motive force from the drive shaft. The housing section houses the motive force transmission system. The clutch is attached between the motive force transmission system and the housing section. The clutch permits relative rotation between the motive force transmission system and the housing section by opening a connection between the motive force transmission system and the housing section during normal rotation of the motive force transmission system. The clutch prevents relative rotation between the motive force transmission system and the housing section by connecting the motive force transmission system and the housing section during a reverse rotation of the motive force transmission system.
