A marine propulsion system for a water craft comprises a relatively large engine or power plant and a power transmission including an output shaft for driving the propeller. The power transmission includes forward and reverse shafts, gear trains between these shafts and the output shaft, and clutches for the forward and reverse shafts. A shaft brake is provided to stop rotation of the output shaft for the propeller which minimizes damaging shocks to the propulsion system which sometimes occur during maneuvering operations. The brake is located concentrically with the forward shaft of the power transmission and is effective to brake the propeller shaft through interconnecting gears when both clutches are disengaged. |
