Description

FIELD OF THE INVENTION

The present invention relates generally to personal watercraft accessories, more specifically but not by way of limitation, a personal watercraft intake grate that is designed to improve the water flow into the impeller cavity while inhibiting debris from entering thereinto.

BACKGROUND

Personal watercraft popularity has exploded in North America over the last decade. The styles, performance and cost of this type of watercraft has enabled many to begin participation in watersports. While there are many manufactures of personal watercraft, the core design of all is basically the same. Personal watercraft employ an engine that powers a drive shaft wherein the drive shaft has operably coupled thereto an impeller. The impeller is located in a drive shaft housing wherein the rotation of the impeller draws water into the housing and the impeller subsequently expels the water outward through a rear nozzle. The drive shaft housing includes a grate that is operable to cover the opening of the water intake for the drive shaft housing.
While stock impellers and other components function well, many personal watercraft owners change out certain parts to enhance the performance of the personal watercraft. This can include but is not limited to impellers. Impellers operate more efficiently when the current volume of water is being supplied thereto. It is common for the intake grate to be exchanged as an effort to increase water volume flow to the impeller. One issue with these is the existing designs of both stock intake grates and aftermarket intake grates is the inability to provide an increase in water flow as well as inhibit debris from entering the drive shaft housing. Debris such as but not limited to rocks often will enter the drive shaft housing due to intake grate design deficiencies.
Accordingly, there is a need for an intake grate for a personal watercraft that provides proper waterflow to the impeller and further inhibits debris from entering the drive shaft housing.

SUMMARY OF THE INVENTION

Another object of the present invention is to provide an intake grate for a personal watercraft configured to provide proper water flow and inhibit debris from egressing therepast wherein the present invention is manufactured from aluminum or similar material.
A further object of the present invention is to provide a personal watercraft intake grate that is configured to inhibit debris from entering the driveshaft housing of a personal watercraft wherein the present invention includes a plurality of longitudinal members.
Yet a further object of the present invention is to provide an intake grate for a personal watercraft configured to provide proper water flow and inhibit debris from egressing therepast that includes a forward mounting plate.
Still another object of the present invention is to provide a personal watercraft intake grate that is configured to inhibit debris from entering the driveshaft housing of a personal watercraft that includes an aft mounting plate secured to the plurality of longitudinal members distal to the forward mounting plate.
An additional object of the present invention is to provide an intake grate for a personal watercraft configured to provide proper water flow and inhibit debris from egressing therepast that further includes a center longitudinal member.
