Jet Pump Wear Ring 155.5mm for Sea-Doo Challenger S 260 1503 2012

Jet Pump Wear Ring for Sea-Doo Challenger S 1503

This jet pump wear ring is a 155.5 mm inner diameter replacement ring that restores proper clearance between the impeller and pump housing on your personal watercraft.

Overview

This jet pump wear ring is designed for the Sea-Doo Challenger S powered by the 1503 engine, keeping the impeller-to-housing gap within spec for strong thrust and smooth acceleration. A worn wear ring causes cavitation and lost top speed, so replacing this jet pump wear ring brings back the performance your craft was built to deliver. It is a practical maintenance part for riders who service their own pump assemblies.

Built For Performance

• 155.5 mm inner diameter sized to match the impeller clearance specification for the 1503 jet pump
• Durable construction resists the abrasion and erosion caused by sand and debris passing through the pump
• Maintains the tight impeller-to-housing tolerance that protects against cavitation
• Direct replacement for the factory wear ring position without pump modification
• Withstands continuous immersion and the heat of high RPM operation

Fits These Machines

• for Sea-Doo Challenger S with the 1503 engine (2012)

On-The-Job Use

• Jet pump assembly maintenance on personal watercraft and jet boats
• Restoring lost top speed and hole shot after ring erosion
• Pre-season service checks on the impeller and housing assembly
• Replacing a scored ring after running in shallow, sandy water

Specs At A Glance

Good To Know

Q: How do I know my wear ring needs replacing? A: Common signs include a drop in top speed, cavitation on acceleration, and visible scoring or a widened gap between the ring and impeller. Measuring the inner diameter against the 155.5 mm spec confirms wear.

Q: Is this an original Sea-Doo part? A: No, this is an aftermarket wear ring manufactured to fit for Sea-Doo applications. It installs in the factory location using standard pump service procedures.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
