Zusammenfassung:A propulsion device for a marine vessel. A base is configured to be coupled to the marine vessel. A shaft includes an upper segment and a lower segment each extending along a length axis, wherein the upper segment is coupled to the base. A propulsor is coupled to the lower segment, where the propulsor is configured to propel the marine vessel in water. A shock absorber includes a resilient member that resiliently couples the upper segment and the lower segment together, where the resilient member dampens impact forces received at the lower segment and reduces transfer of the impact forces to the upper segment.
