A system according to the principles of the present disclosure includes a profile storage module, a profile playback module, and a speed control module. The profile storage module stores an acceleration profile specifying a manner of accelerating a marine vessel. The profile playback module, in response to a play command received from a vessel operator, retrieves the acceleration profile and adjusts a desired engine speed based on the acceleration profile. The speed control module controls an engine speed of the marine vessel based on the desired engine speed.

Engine control system and method for a marine vessel

A system for a watercraft includes memory, a communications module, and a throttle control module. The memory includes a first mapping of measured accelerator position to desired throttle opening. The communications module selectively downloads a second mapping of the measured accelerator position to the desired throttle opening to the memory. The throttle control module generates the desired throttle opening based on the measured accelerator position and a selected one of the first and second mappings. A throttle actuator module opens a throttle valve based on the desired throttle opening.

Watercraft throttle control systems and methods

A control system for a vehicle that includes an engine includes a speed generation module, an airflow determination module, and a throttle control module. The speed generation module generates a desired engine speed during a period after a measured vehicle speed is greater than or equal to a desired vehicle speed, wherein the desired engine speed is based on a difference between the desired vehicle speed and the measured vehicle speed. The airflow determination module determines a desired airflow based on a difference between the desired engine speed and a measured engine speed. The throttle control module determines a desired throttle position based on the desired airflow, and commands a throttle of the engine to the desired throttle position.
