A hose fitting is provided to fluidly couple a hose to a component of a boat engine. The hose fitting includes a lead in portion having a substantially smooth exterior surface, a barbed portion with multiple barbs configured to sealingly engage with an inner liner of the hose, a grip portion with multiple substantially flat grip faces; and a terminating portion configured to couple to the component of the boat engine. The lead in portion, the barbed portion, the grip portion, and the terminating portion collectively define a central flow passage extending through the hose fitting.

Hose fitting and hose assembly for marine vehicles

A control mechanism is provided for a jet propelled watercraft that enables an operator to engage and disengage a braking gate with hand pressure using a lever on the handlebar of the watercraft. Hydrodynamic assist devices are provided to assist the operator during the engagement and disengagement of the brake by counteracting both rejecting forces and retaining forces exerted on the gate by the stream of water ejected from the nozzle of the jet propulsion device. During initial insertion of the gate into the stream of water, a first hydrodynamic assist device counteracts the rejection forces otherwise exerted by the stream of water against a deflecting surface of the gate. After full deployment of the gate within the stream of water, a second hydrodynamic assist device opposes the retaining forces exerted on the gate and reduce the magnitude of the force necessary to be exerted by the operator to move the gate out of the stream of water and disengage the brake. Combinations of the two hydrodynamic assist devices can be tailored to result in an appropriate force profile necessary to be exerted by the operator during the engagement and disengagement procedures.

Braking system for a watercraft

A reverse mechanism for a jet propelled watercraft includes a reverse gate that provides low restriction to the flow of water through the jet pump, and also provides significant steering characteristics. The reverse gate has a deflector surface with a vertical jet divide that divides the deflector surface. Both sides of the deflector surface are in the form of a simple curve. In the preferred embodiment, the simply-curved deflector surfaces slant inward towards a central apex which serves as the vertical jet divide. The deflector surface spans between a starboard side support structure and a port side support structure which are pivotally mounted along a horizontal axis so that the reverse gate can be moved between a full-up position and a full-down position rearward of the jet pump. Both the starboard side support structure and the port side support structure include apertures therethrough which allow a portion of the jet flow to exit laterally from the reverse gate. When the reverse gate is in the fully down position, a portion of the jet flow is redirected forward to provide reverse thrust, and a portion of the jet of water is deflected laterally to port and laterally to starboard proportionally in accordance with the direction of the jet pump rudder.
