Is your Sea-Doo losing top end speed or acceleration? Feeling vibration? Chances are the wear ring inside your jet pump is worn out. This RAREELECTRICAL replacement wear ring is a brand new, high-quality part designed to fit a ton of Sea-Doo models with the 1503 engine platform. It's a direct replacement for OEM numbers like 267000104, 271001236, 267000419, and 267000021. It fits models from 2004 up to 2019, including the GTX (Limited, S/C, Wake), GTI (SE, Ltd, 130, 155), and Challenger series. The internal diameter is 155.5mm. A fresh wear ring restores the tight clearance between the ring and the impeller, which is crucial for creating thrust and efficiency. Installation requires removing the jet pump, but it's a standard maintenance item. This is a NEW part (not remanufactured), built to handle saltwater and abuse, and it ships from the USA. Always verify your old part number or your specific Sea-Doo model/year to ensure a perfect fit before ordering.
