Abstract
Official abstract text for this publication.
A marine vessel includes a plurality of turning mechanisms provided respectively in correspondence to a plurality of outboard motors. Each turning mechanism includes a hydraulic pump, an electric motor to drive the hydraulic pump, a hydraulic cylinder including two cylinder chambers partitioned by a piston, and a normally-closed bypass valve to put the two cylinder chambers of the hydraulic cylinder into communication with each other. Upon judging that there is a malfunction in the turning angle control of at least one of the outboard motors, a main ECU displays on a display an operation guidance screen to urge a marine vessel operator to open the bypass valve of the turning mechanism corresponding to the malfunctioning outboard motor. Also, the main ECU keeps a power transmission between an engine and a propeller in the malfunctioning outboard motor in an interrupted state.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of operating a marine vessel propulsion system including a plurality of outboard motors, each of the plurality of outboard motors including a motor and a propeller rotated by the motor, and a steering apparatus arranged to control turning angles of the plurality of the outboard motors and the steering apparatus including a steering member and a plurality of turning mechanisms arranged to turn each of the plurality of outboard motors individually in a…
