Hydraulic system for marine propulsion device with sequentially operating tilt and trim means

摘要

Disclosed herein is a marine propulsion device comprising a first pivot connecting a stern bracket to a transom bracket for pivotal movement therebetween about a first pivot axis which is horizontal when the transom bracket is boat mounted, a second pivot connecting the swivel bracket to the stern bracket for pivotal movement of the swivel bracket with the stern bracket and relative to the stern bracket about a second pivot axis parallel to the first pivot axis, a propulsion unit including, at the lower end thereof, a rotatably mounted propeller and connected to the swivel bracket for steering movement therebetween and for common pivotal movement, a trim cylinder-piston assembly pivotally connected to the stern bracket and to the swivel bracket and including first and second ends, a tilt cylinder-piston assembly pivotally connected to the transom bracket means and to the stern bracket and including first and second ends, and a hydraulic system for sequentially operating the tilt and trim cylinder-piston assemblies.
