Abstract
A steering system for a trimmable outboard motor. The steering system includes a hydraulic steering device that upon actuation changes a steering angle of the outboard motor. A pump communicates a hydraulic fluid with the hydraulic actuator to cause actuation thereof, where the pump operates at a pump speed, and where the pump speed impacts a change rate for the hydraulic steering device changing the steering angle. A reservoir is fluidly coupled to the pump and configured to retain the hydraulic fluid. A tilt sensor detects a trim angle of the outboard motor. A control system is operatively coupled with the pump and receives requests for changing the steering angle. The control system controls the pump speed of the pump based at least in part on the trim angle of the outboard motor.
