Title:
WATER JET PROPULSION BOAT
Document Type and Number:
Japanese Patent JP2014024534
Kind Code:
A
Abstract:

To provide a water jet propulsion boat capable of providing natural deceleration performance in response to operation by an operator.

A water jet propulsion boat comprises a hull, an engine, a jet propulsion mechanism, a first accelerator operation part 41, a second acceleration operation part 42, a reverse gate and a control part. The engine is stored in the hull. The jet propulsion mechanism generates propulsive power by driving force from the engine. The reverse gate can move to a first position and a second position. The reverse gate advances the hull in the first position. The reverse gate reduces the propulsive power for advancing the hull in the second position. The control part determines a position of the reverse gate and throttle opening of the engine based on an operation quantity of the first accelerator operation part and an operation quantity of the second accelerator operation part.
