Abstract: A marine outboard engine has upper and lower engine covers, a swivel bracket, a stern bracket, an engine, a driveshaft, a gear case, a propeller shaft, and a variable pitch propeller. A hydraulic system includes hydraulic steering, trim, and propeller pitch actuators, and at least one valve having at least one inlet, and first, second, and third outlets. The first, second, and third outlets fluidly communicate with the hydraulic steering, trim, and propeller pitch actuators respectively. A pump fluidly communicates with the at least one inlet of the at least one valve. A reservoir stores hydraulic fluid. A control unit controls the at least one valve to control a flow of hydraulic fluid through each of the first, second, and third outlets based at least in part on a signal received from a pressure sensor. Methods of controlling the hydraulic systems are also disclosed.

Abstract: A marine outboard engine is disclosed which comprises a drive unit, a tilt/trim/steering subsystem and a stern bracket adapted for connection to an associated watercraft. The tilt/trim/steering subsystem connects the drive unit to the stern bracket and comprises a first rotary actuator carrying the drive unit for pivotal movement about a steering axis that extends generally vertically, and a second rotary actuator connected to the first rotary actuator and supporting the first rotary actuator and the drive unit for pivotal movement about a tilt/trim axis that extends generally horizontally.
