Shift system for a marine drive

A marine drive includes an internal combustion engine that drives a propulsor into rotation to effect a thrust, and a transmission that shifts amongst a forward gear for a forward thrust, a reverse gear for a reverse thrust, and a neutral state for a zero thrust. The marine drive further includes a...

Beschreibung
Zusammenfassung:	A marine drive includes an internal combustion engine that drives a propulsor into rotation to effect a thrust, and a transmission that shifts amongst a forward gear for a forward thrust, a reverse gear for a reverse thrust, and a neutral state for a zero thrust. The marine drive further includes a shift rod rotatable about its own axis to shift the transmission amongst forward, reverse, and neutral, and an actuator. The actuator includes an actuator motor that rotates an output shaft and a gear shaft that effectuates rotation of a shift rod. The output shaft is connected to a gear shaft through a first gearset such that rotation of the output shaft causes the rotation of the gear shaft, and the gear shaft is connected to the shift rod through a planetary gearset such that rotation of the gear shaft causes the rotation of the shift rod.
