Abstract
A jet pump assembly includes a marine engine, a jet drive and a shield adapted to be secured to a transom of a watercraft. The shield has arms to which the marine engine is secured and legs to which the jet drive is secured, the arms and legs extending in opposite directions. The shield has a flange adapted to be secured to the transom of the watercraft. The shield covers an opening in the transom through which the jet pump assembly is passed during assembly. A gasket between the shield and transom prevents water from entering the watercraft.
Claims20
A jet pump assembly for attachment to a transom of a watercraft, the jet pump assembly comprising:
- a marine engine;
- a jet drive including a rotatable shaft configured to receive torque from the marine engine;
- and
- a shield adapted to be secured to the transom of the watercraft, wherein the shield has parallel arms to which the marine engine is secured and parallel legs to which the jet drive is secured, the arms and legs of the shield extending in opposite directions,
- wherein the rotatable shaft extends through an opening in the shield.
In combination, a watercraft and a jet pump assembly, the combination comprising:
- a watercraft having a transom with an opening therein,
- a jet pump assembly comprising:
- a marine engine;
- a jet drive including a rotatable shaft configured to receive torque from the marine engine;
- and
- a shield secured to the transom of the watercraft and located behind the transom of the watercraft, the shield having two hollow parallel legs to which the jet drive is secured and two hollow parallel arms to which the marine engine is secured,
- wherein the rotatable shaft extends through an opening in the shield and the shield covers the opening in the transom of the watercraft.
A method of installing a jet pump assembly to a watercraft, the method comprising:
- securing a jet drive and a marine engine to a shield;
- passing the marine engine at least partially through an opening in a transom of the watercraft;
- and
- securing a flange of the shield to a transom of the watercraft.
A method of installing a jet pump assembly to a watercraft, the method comprising:
- building a jet pump assembly by securing a jet drive and a marine engine to a shield, the shield having an opening through which a portion of the jet drive extends, the marine engine being coupled to the jet drive to power the jet drive;
- passing a portion of the jet pump assembly through an opening in a transom of the watercraft;
- and
- securing the shield to the transom of the watercraft.
