Marine Boat Water Jet Pump Propulsion

Water-jet Overview

Water-jet propulsion pump discharging of a high velocity jet stream generates a reaction force in the opposite direction, which is transferred through the body of the jet unit to the craft's hull, propelling it forward. It works in relation to Newton's Third Law of Motion - "Every action has an equal and opposite reaction". 

Water-jet propulsion advantages

Reliability
Water-jets have fewer moving parts and most major components inboard, minimizing the chance accidental damage and increasing the life of components.

Excellent Manoeuvreability
Precise steering control at all boat speeds. "Zero Speed" steering effect provides 360° thrusting ability for docking and holding stationary. Sideways movement possible with multiple jet installations.

High Speed
Water-jets are designed to be optimized for vessel speeds from 25-50 knots, dependent on application's engineering variables including hull resistance and type, engine power rating and rpm, impeller rating, etc.

Shallow Draught
Water-jet intake is flush with hull bottom to allow access to shallow water areas and beach landings with no risk of damage to the drive.

Total Safety
No exposed propeller for complete safety around people in the water and marine life.
