Method and system for controlling a marine drive during shift sensor fault

Abstract

A system for controlling propulsion of a marine vessel by a marine drive is provided, the marine drive having a marine engine that effectuates rotation of propulsor through a shift system that shifts amongst at least a forward gear position, a reverse gear position, and a neutral position. The system includes a remote control having a lever movable to provide a throttle demand input for controlling the marine engine and a shift demand input for controlling the shift system. A shift demand sensor measures a shift demand lever position to provide the shift demand input, and a throttle demand sensor measures a throttle demand lever positions to provide the throttle demand input. A control module is configured to detect shift demand sensor failure based on the shift demand lever position values and assign a predetermined throttle demand lever position as shift command position. When the throttle demand lever position reaches the shift command position, a shift command is generated instructing a change in gear position of the shift system.
