WSM Performance 003507 Jet Pump Housing — Yamaha PWC
Free returns on all eligible orders
You have 30 days to request a return. All sale items are final sale.
A direct-replacement jet pump housing for Yamaha personal watercraft, built to WSM Performance specifications. The pump housing is the core structural shell of the jet propulsion system — it contains the impeller, wear ring, and bearing assembly and is vulnerable to impact damage, stress cracking, and erosion from cavitation and debris ingestion. Replacing a compromised housing restores correct water flow geometry and protects the internal pump components from accelerated wear.

Parts Desk Insights
Housing replacement is the right call when inspection reveals cracking, deep erosion grooves around the impeller bore, or structural distortion that a wear ring swap alone cannot address. This is a structural repair part — not a routine maintenance item. For routine pump rebuilds on Yamaha models, see the WSM 003627 Jet Pump Repair Kit. If you’re unsure whether you need the 003507 or the 003508 (a sibling housing at a slightly higher price point), fitment is model-specific — confirm your exact Yamaha model and year against the WSM application guide before ordering, as the two housings serve different Yamaha configurations.
