Abstract:
1. A system for a watercraft, comprising: memory that includes a first mapping of measured accelerator position to desired throttle opening; a first electronic circuit that selectively downloads a second mapping of the measured accelerator position to the desired throttle opening to the memory; a second electronic circuit that compares an actual number of data points in the second mapping with a predetermined number of data points for the second mapping, each of the data points relating a measured accelerator position to a desired throttle opening; a third electronic circuit that selects one of the first and second mappings, wherein the third electronic circuit selects the second mapping when the measured accelerator position is equal to a predetermined engine idling position and the predetermined and actual numbers are equal; and a fourth electronic circuit that generates the desired throttle opening based on the measured accelerator position and the selected one of the first and second mappings, wherein a fifth electronic circuit opens a throttle valve based on the desired throttle opening.
