A method for controlling a marine engine for propelling a marine vessel includes receiving user input as a user input device to control acceleration of a marine vessel, detecting a rapid acceleration command based on the user input, and determining an advanced spark timing based on at least one of engine speed and engine load, wherein the advanced spark timing adjusts a base spark time by a spark advance offset. A fuel increase is then determined based on the spark advance offset, and then an increased fuel injection amount is determined by increasing a base fuel injection amount by the fuel increase. Spark and fuel delivery are then controlled for one or more cylinders of the marine engine based on the advanced spark timing and the increased fuel injection amount.

Method and control system for controlling a marine internal combustion engine

A recoil starter has a guide surface with limited polar symmetry about the axis of the pull-rope limiting rotational orientation of the pull-handle in the at-rest position to less than three angular positions.

A connection device for a marine propulsion system is provided in which a selective locking mechanism automatically connects or disconnects two components of the marine propulsion system together in response to rotation of a tube and a rod. This relative rotation of the tube and rod is caused automatically when one of the components of the marine propulsion system is rotated relative to the other component.
