ABSTRACT:
A marine propulsion water jet system which operates at high efficiency and automatically adjusts itself to maintain a relatively constant primary injection water velocity over a wide speed range. The propulsion system includes a fluid flow amplifier by which a high velocity principal water flow is injected into a slower velocity secondary water flow to form a water jet. The fluid flow amplifier includes an adjustable orifice through which the principal water flow is injected into the secondary water flow and the size of the orifice is automatically adjusted in order to maintain a relatively constant water jet velocity.
