Water Sports 003-507 Jet Pump Housing 144mm Yamaha PWC

The WSM Performance 003-507 is an inexpensive replacement for the stock pump housing designed for Yamaha personal watercraft. This aftermarket jet pump housing addresses common issues with original equipment, as OEM impeller housings are known to warp and dimple due to corrosion between dissimilar metals.

Key Features:

• Includes wear ring, made to the same size as the OEM Yamaha part with an upgraded removable plastic wear ring
• Wear ring internal diameter: 144mm / 5-5/8"
• Aluminum housing with plastic wear ring, instead of the thin stainless steel liner that corrodes and bulges
• Very low cost plastic wear-ring liner is easy to remove and replace
• Uses replacement wear ring part number 003-521 (sold separately)

OEM Cross-Reference: Replaces Yamaha part numbers 6R7-51312-00-94, 6R7-51312-01-94, 6R7-51312-02-94, 6R7-51312-03-94, and 6R7-51312-03-00.

This housing provides a cost-effective solution with the added benefit of a replaceable wear ring system, eliminating the need to purchase an entire housing when the wear ring becomes damaged from rocks, debris, or worn bearings.
