A braking system for a personal watercraft includes at least one brake plate for mounting to the transom of a personal watercraft such that the jet nozzle of the watercraft is directionally adjustable independently of the braking system. The brake plate is alternatable between a nonbraking condition wherein the plate is retracted against the transom and is held completely above a lower edge of the transom, and a braking condition where the brake plate extends beyond the lower edge of the transom. A hand-controlled actuator assembly selectively alternates the brake plate between the braking and nonbraking conditions.

What is claimed is: 1. A braking system for a personal watercraft, which watercraft includes a hull having a transom located proximate the stern thereof and a jet nozzle that directs propulsive water flow rearwardly of the transom to drive the watercraft forwardly, the nozzle being directionally adjustable by operator controls independently of said braking system for steering the watercraft; said braking system comprising: at least one brake plate for mounting to the transom; said brake plate being alternatable between a nonbraking condition wherein said plate is retracted against the transom and held completely above a lower edge of the transom, and a braking condition wherein said brake plate extends beyond the lower edge of said transom; and a hand-controlled actuator assembly for selectively operating said brake plate to alternate said brake plate between said nonbraking and braking conditions, said brake plate being mountable to the transom such that the nozzle is directionally adjustable relative to the transom and independently of the operation of said brake plate. 2. The system of claim 1 wherein a pair of brake plates are mounted to the transom on respective sides of the jet nozzle. 3. The system of claim 2 in which said actuator includes at least one hand-controlled lever, an actuator cable assembly responsively interconnected to said hand-controlled lever and a linkage assembly for interconnecting said cable assembly and each brake plate and for driving said plates into said braking condition when said hand-controlled lever is operated. 4. The system of claim 2 wherein said brake plates are operated to simultaneously alternate between the braking and nonbraking condition and wherein each brake plate is for disposing on a respective side of the nozzle such that said brake plates perform braking exclusively in the extended position and do not perform steering of the watercraft. 5. The system of claim 3 in which each brake plate is mounted slidably in a respective support track that is securable to the transom. 6. The system of claim 5 in which each said plate includes a guide slot and said linkage includes a bearing movably interengaging said slot, and a fulcrum component carrying said bearing, said fulcrum component being pivotally mounted to said track and biased by a spring to pull said plate retractably into said nonbraking condition in said track, said linkage further including an actuator bar for interconnecting said fulcrum component and said cable and being longitudinally driven in response to operation of said hand-controlled lever to drive said fulcrum component pivotably against said spring and urge said plate to slide within said track into an extended, braking condition therein. 7. The system of claim 6 in which a single actuator bar interconnects a fulcrum component associated with a first one of said brake plates and a distinct fulcrum component associated with the other said brake plate, said bar being driven longitudinally by said cable in response to operation of said lever for pivotally pulling said first fulcrum component and pivotally pushing the other said fulcrum component to urge said plates to slide into the extended braking condition in said respective tracks. 8. The system of claim 1 in which said plate is mounted in a support track securable to the transom, said track including a base panel having a pair of inwardly turned lips formed along respective sides thereof, said lips defining vertical channels that receive said plate such that said plate flushly and slidably interengages said base panel. 9. A personal watercraft with independently controlled steering and braking systems, said watercraft comprising: a hull having a transom located proximate the stern of said hull; a jet nozzle for directing propulsive water flow rearwardly of said transom to drive the watercraft forwardly, said nozzle being directionally adjustable relative to said transom by operator controls for steering the watercraft; a pair of brake plates for mounting to said transom on respective sides of said jet nozzle, said brake plates being simultaneously alternatable between a nonbraking condition wherein said plates are retracted against said transom and held completely above a lower edge of said transom and a braking condition wherein said plates extend beyond the lower edge of said transom; and a hand-controlled actuator assembly for selectively operating said brake plates to alternate between said braking and nonbraking conditions, said brake plates being attached to said transom such that said nozzle is directionally adjustable relative to said transom and independently of the operation of said brake plates. 10. The system of claim 9 in which said actuator includes at least one hand-controlled lever, an actuator cable assembly responsively interconnected to said hand-controlled lever and a linkage assembly for interconnecting said cable assembly and each brake plate and for driving said plates into said braking condition when said hand-controlled lever is operated. 11. The system of claim 10 in which each brake plate is mounted in a respective support track that is securable to the transom. 12. The system of claim 11 in which each said plate includes a guide slot and said linkage includes a bearing movably interengaging said slot, and a fulcrum component carrying said bearing, said fulcrum component being pivotally mounted to said track and biased by a spring to pull said plate retractably into said nonbraking condition in said track, said linkage further including an actuator bar for interconnecting said fulcrum component and said cable and being longitudinally driven in response to operation of said hand-controlled lever to drive said fulcrum component pivotably against said spring and urge said plate to slide within said track into an extended, braking condition therein. 13. The system of claim 12 in which a single actuator bar interconnects a fulcrum component associated with a first one of said brake plates and a distinct fulcrum component associated with the other said brake plate, said bar being driven longitudinally by said cable in response to operation of said lever for pivotally pulling said first fulcrum component and pivotally pushing the other said fulcrum component to urge said plates to slide into the extended braking condition in said respective tracks. 14. The system of claim 9 in which said operator controls include a control handle that is turned in a selected direction to direct said nozzle so that said nozzle propels the watercraft in the selected direction. 15. The system of claim 9 in which said brake plates are mounted to said transom on respective sides of an opening through which said nozzle is directed. 16. The system of claim 15 in which said brake plates perform braking exclusively and steering is performed exclusively by said nozzle. 17. A braking system for a personal watercraft, which watercraft includes a hull having a transom located proximate the stern thereof and a jet nozzle that directs propulsive water flow rearwardly of the transom to drive the watercraft forwardly, the nozzle being directionally adjustable by operator controls independently of said braking system for steering the watercraft; said braking system comprising: at least one brake plate for mounting to the transom such that the nozzle is directionally adjustable independently thereof; said brake plate being alternatable between a nonbraking condition wherein said plate is retracted against the transom and held completely above a lower edge of the transom, and a braking condition wherein said brake plate extends beyond the lower edge of said transom, said brake plate being mounted in a support track securable to the transom, said track including a base panel having a pair of inwardly turned lips formed along respective sides thereof, said lips defining vertical channels that receive said plate such that said plate flushly and slidably interengages said base panel; and a hand-controlled actuator assembly for selectively alternating said brake plate between said nonbraking and braking conditions.
