Abstract
A drivetrain for a marine propulsion device includes an engine driving a crankshaft in a first direction, and a driveshaft connected in torque-transmitting relationship with the crankshaft and supported for rotation about a driveshaft axis. The drivetrain further includes a propeller shaft rotatable about a propeller shaft axis. A gearset and a selector clutch are configured to couple the propeller shaft and the driveshaft to each other in torque-transmitting relationship. A one-way clutch is disposed along the drivetrain upstream of the gearset. The one-way clutch prevents rotation of the crankshaft in a second, opposite direction so as to prevent ingestion of water by the engine via an engine exhaust system.
