DRIVE SOURCE SWITCHING SYSTEM FOR MARINE PROPULSION DEVICE INCLUDING MULTIPLE DRIVE SOURCES, AND METHOD OF SWITCHING DRIVE SOURCES OF MARINE PROPULSION DEVICE

摘要

A drive source switching system for a marine propulsion device includes a first drive source, a second drive source, a propeller shaft, a first driving member, a second driving member, a first driven member, and a second driven member that are movable in an axial direction of the propeller shaft, and a controller. The first driven member transmits a drive force generated by the first drive source to the propeller shaft when engaged with the first driving member. The second driven member transmits a drive force generated by the second drive source to the propeller shaft when engaged with the second driving member. When the controller moves the first driven member that is not engaged with the first driving member toward the first driving member, the controller moves the first driven member back when the first driven member fails to be engaged with the first driving member.
