Abstract
In a jet-propelled boat, a nozzle of a jet pump is constructed so as to be rotatable in response to steering by a rider of the boat in order to change a course of the boat. A rudder, that does not project downwards further than a boat bottom, is attached to an outer surface of the nozzle. A jet pump channel is provided for guiding a water flow to the jet pump. A rudder channel is provided separate from the jet pump channel and guides a water flow to the rudder. When a driving speed of the jet pump is stopped or slowed, the rudder will enable the course of the boat to be steered when the boat continues to move through the water due to its own inertia. The steering occurs because the direction of the nozzle and hence the rudder can be controlled by the boat's rider, and water will continue to be delivered to the rudder via the rudder channel. The rudder may be duct-shaped. Further, a plate may be provided to selective block an inlet of the rudder channel, with the plate opening the rudder channel when a driving speed of the jet pump is a prescribed value or less.
