Claims
- 1. In a jet powered boat comprising a hull, a fluid jet conduit having an intake along the bottom of the hull, and a jet outlet at the rear of the hull, a drive motor for propelling water from the intake trough the conduit to jet outlet, and an operator control station within the hull, wherein the operator control station contains controls for the drive motor and the jet outlet, the improvement comprising:an outlet water monitor mounted on the top of the hull, wherein the water monitor is movable to direct a stream of water in one of a plurality of directions; a hull opening through the bottom of the hull; a water conduit connecting the hull opening to the outlet monitor; and a pump engine connected to the conduit for drawing water substantially vertically through the hull opening and the conduit to the outlet monitor.
- 2. The improved jet powered boat of claim 1, wherein the hull opening is nearer to the longitudinal centerline of the hull than it is to the side of the hull.
- 3. The improved jet powered boat of claim 2, wherein the hull opening is on the longitudinal centerline of the hull.
- 4. The improved jet powered boat of claim 3, wherein the pump engine is mounted inside the hull on the longitudinal centerline of the hull.
- 5. The improved jet powered boat of claim 1, additionally comprising a second outlet water monitor mounted on the top of the hull, wherein the second water outlet monitor is movable to direct a second stream of water in any of a plurality of directions, wherein:the water conduit connects the hull opening to the first water outlet monitor and to the second water outlet monitor; and the pump engine draws water through the water conduit from the hull opening to the first outlet monitor and to the second outlet monitor.
- 6. The improved jet powered boat of claim 5, wherein the first and second water outlet monitors are mounted on the forward portion of the hull.
- 7. The improved jet powered boat of claim 1, additionally comprising a secondary conduit connecting the pump engine with the jet outlet at the rear of the hull.
- 8. The improved jet powered boat of claim 7, additionally comprising valving to selectively control whether the pump engine directs water through the water conduit to the outlet monitor, or through the secondary conduit to the jet outlet.
- 9. A jet powered boat comprising:a hull; a propulsion water conduit having a propulsion intake through the bottom of the hull and a propulsion outlet at the rear of the hull; a first motor connected to the propulsion water conduit for directing water through the propulsion conduit from the propulsion intake to the propulsion outlet; a water monitor attached to the upper side of the hull; a substantially vertical monitor intake opening through the bottom of the hull; a monitor water conduit connecting the monitor intake to the water monitor; and a second motor connected to the monitor water conduit for directing water through the monitor water conduit from the monitor intake opening to the water monitor.
- 10. The jet powered boat of claim 9, wherein the monitor intake opening is closer to the longitudinal centerline of the hull than it is to the sides of the hull.
- 11. The jet powered boat of claim 10, wherein the monitor intake opening is along the longitudinal centerline of the hull.
- 12. The jet powered boat of claim 11, additionally comprising:a second propulsion water conduit intersecting the monitor water conduit at a point between the second motor and the water monitor, wherein the second propulsion water conduit has a second propulsion outlet at the rear of the hull; a movable baffle in the monitor water conduit at the point at which the monitor water conduit and the second propulsion water conduit intersect, wherein: the baffle is movable between a monitor position and a propulsion position; when the baffle is in the monitor position, the baffle directs water through the monitor conduit, but substantially restricts the flow of water through the second propulsion conduit; and when the baffle is in the propulsion position, the baffle directs water from the monitor water conduit into the second propulsion conduit.
- 13. The jet powered boat of claim 12, additionally comprising:a second propulsion intake through the bottom of the hull, wherein the second propulsion intake is connected to the monitor water conduit; and a flow controller to selectively control whether water enters the monitor water conduit through the monitor intake opening or through the second propulsion intake.
- 14. The jet boat of claim 12, additionally comprising a control connection between operator position and the baffle for moving to baffle between the first position and the second position.
- 15. The jet boat of claim 14, wherein the control connection comprises a cable connected to the baffle.
- 16. The jet boat of claim 14, wherein the first and second motors are mounted in the hull on opposite sides of the centerline of the hull.
- 17. The jet powered boat of claim 9, wherein:the monitor intake opening is on one side of the longitudinal centerline of the hull, closer to the longitudinal centerline than to the side of the hull; the propulsion intake is on the opposite side of the longitudinal centerline of the hull, closer to the longitudinal centerline than to the side of the hull.
- 18. In a boat comprising a hull, a drive motor for propelling the hull through water, and an operator station within the hull, wherein the operator control station contains controls for the drive motor, the improvement comprising:an outlet water monitor mounted on the of the hull, wherein the water monitor is movable to direct a stream of water in one of a plurality of directions; a hull opening through the bottom of the hull; a water conduit connecting the hull opening to the outlet monitor; and a pump engine mounted in the hull and connected to the conduit for drawing water substantially vertically through the hull opening and into the conduit to the outlet monitor.
