Water jet propelling vessel |
摘要 |
Several embodiments of jet propelled water vessels wherein the bull and jet propulsion unit cooperate to form an inlet opening so that the outer housing of the jet propulsion unit need not itself form the inlet. This facilitates servicing since the water inlet need not be removed along with the jet propulsion unit for servicing and minimizes the likelihood of damage to the inlet duct and support for the impeller shaft.
