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.

Abstract
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.
