Title:
水ジェット推進艇の速度制御装置
Document Type and Number:
Japanese Patent JP4420738
Kind Code:
B2
Abstract:
A watercraft can have a controller that can change a speed mode between a speed set mode and a regular mode in response to an operation of an auto cruise switch. The controller can return the speed mode to a regular mode under various conditions. For example, but without limitation, when an engine rotational speed reaches "zero" or nearly "zero" (i.e., an engine operation stops or nearly stops) while the speed mode is in the speed set mode. The controller can be configured to follow the actuation of the cruise switch only when the switch is operated in the regular mode.
