Abstract
A transmission is for an outboard marine engine. The transmission comprises a rotatable input shaft that is rotated by an internal combustion engine, a rotatable output shaft that powers a propulsor, a forward gear that causes forward rotation of the output shaft and propulsor, a reverse gear that causes reverse rotation of the output shaft and propulsor, a clutch that is movable between a forward clutch position wherein the forward gear causes the forward rotation of the output shaft and propulsor and a reverse clutch position wherein the reverse gear causes the reverse rotation of the output shaft and propulsor, and an internal ring gear that couples the output shaft to one of the forward gear and the reverse gear.
