Description
The WSM Replacement Pump Wear Ring for Sea-Doo 1503/1630 (12-23) is a critical wear item that controls the gap between the impeller and the pump. As the ring wears the gap grows and the pump loses bite. That can feel like cavitation on holeshot and a soft pull in the midrange. Installing a fresh wear ring helps restore a tighter seal so the pump can build pressure and move water efficiently.
This is a smart move during an impeller swap or any pump service. A new ring can make the ski feel sharper and more predictable under load without changing your engine setup.
