A system for rotating a propeller shaft within a gearcase via a driveshaft. A stub shaft is rotatable within the gearcase. A forward gear is rotatably coupled to the stub shaft. The forward gear is rotatable by the driveshaft and is engageable to become rotatably fixed to the stub shaft such that rotating the driveshaft rotates the stub shaft. A shock absorbing coupler is positioned within the gearcase. The shock absorbing coupler couples the stub shaft to the propeller shaft and is torsional such that shock is absorbable between the propeller shaft and the driveshaft.
