INLET GRATE FOR A WATER JET PROPULSION SYSTEM
First Claim
1. An inlet grate for a water jet propulsion system to be used in a watercraft, the water jet propulsion system having a water passage, the water passage having an inlet, the inlet having a forward area and a rearward area with respect to the watercraft, the inlet grate comprising:
- a first end portion including a plate adapted to be connected to the forward area of the inlet, the plate being adapted to be disposed at least in part inside the water passage when the grate is installed on the jet propulsion system;
a second end portion adapted to be connected to the rearward area of the inlet;
at least one elongated member extending from the first end portion toward the second end portion; and
at least one deflector having a forward end and a rearward end, the at least one deflector being in contact with the plate,the at least one deflector extending rearward and upward from the first end portion toward the second end portion,the at least one deflector being inclined relative to the elongated member such that at least a portion of a top surface and the rearward end of the at least one deflector are spaced from the plate in a direction perpendicular to the at least one elongated member, andthe rearward end of the at least one deflector being disposed inside the water passage when the grate is installed on the jet propulsion system.

Abstract
An inlet grate for a water jet propulsion system to be used in a watercraft has a water passage having an inlet defined by a forward and a rearward area with respect to the watercraft. The inlet grate comprises a first end portion adapted to be connected to the forward area of the inlet and a second end portion adapted to be connected to the rearward area of the inlet as well as at least one elongated member extending from the first end portion toward the second end portion. The inlet grate also comprises at least one deflector having a forward end and a rearward end, the forward end being adjacent to the first end portion of the inlet grate.

13. A watercraft comprising:
-
a hull; a deck disposed on the hull; a water jet propulsion system connected to the hull and having a water passage, the water passage having an inlet, the inlet having a forward area and a rearward area, the water passage being defined at least in part by a wall extending upwardly and rearwardly from a forward area of the inlet; an engine supported by the hull and adapted to drive the water jet propulsion system; at least one elongated member extending from the forward area of the inlet toward the rearward area of the inlet; a plate connected to the forward area of the inlet; and at least one deflector having a forward end and a rearward end, the at least one deflector being in contact with the plate, the at least one deflector extending rearward and upward from the forward area of the inlet toward the rearward area of the inlet, the at least one deflector being inclined relative to the inlet such that at least a portion of a top surface and the rearward end of the at least one deflector are spaced from the wall in a direction perpendicular to the at least one elongated member, the rearward end of the at least one deflector being disposed inside the water passage, and the at least one deflector being adapted to deflect a portion of water entering the water passage away from the wall.
