摘要： A watercraft has an engine that is controlled to provide a comfortable and natural operational feeling during an off-throttle steering environment. The engine is controlled by detecting engine speed, using the detected engine speed to establish an accurate watercraft speed, and detecting an operator steering torque and operator engine torque request. An operational characteristic of the engine is adjusted to increase the engine output by a predetermined amount after a predetermined steering torque is measured and the watercraft is determined to be in a predetermined deceleration phase. The operational characteristic can be an increase in airflow to the engine.

摘要： A small watercraft includes an engine and an improved induction and charging forming system. The engine includes a fuel injection system with at least one fuel injector and a fuel delivery conduit for supplying fuel to the at least one fuel injector. The induction system includes an intake box configured to protect the at least one fuel injector and the fuel delivery conduit from damage that can be caused by heat generated from a portion of an exhaust system and/or water that may collect in a hull of the watercraft. The induction system can also include a set of throttle bodies. Each throttle body includes a throttle valve. The throttle valves are connected to a throttle shaft assembly. A pulley is attached to the throttle shaft assembly and is disposed between adjacent throttle bodies.
