Jet Pump Wear Ring 155.5mm for Sea-Doo Challenger SE 310 2010-2011

Jet Pump Wear Ring (155.5 mm ID) for Sea-Doo

This jet pump wear ring is a replacement component for 155.5 mm inside diameter applications, designed to restore the close clearance between the impeller and pump housing in personal watercraft and jet boats.

Overview

The jet pump wear ring serves as the sacrificial surface inside the pump housing, keeping the impeller-to-housing clearance tight so the pump moves water efficiently. Installing a fresh jet pump wear ring helps reduce cavitation and lost thrust caused by a worn or scored ring. This jet pump wear ring is intended for riders and mechanics servicing 155.5 mm ID pump assemblies.

Built For Performance

• 155.5 mm inside diameter sizing for the specified jet pump housing
• Maintains impeller-to-housing clearance for consistent thrust
• Serves as the replaceable wear surface inside the pump
• Helps reduce cavitation and slippage as the ring wears
• Direct-fit replacement for worn or grooved rings

Fits These Machines

• for Sea-Doo Challenger 310
• for Sea-Doo Challenger SE 310
• for Sea-Doo 1503-powered models using the 155.5 mm ID pump ring

On-The-Job Use

• Routine jet pump rebuilds and seasonal maintenance
• Restoring performance after impeller damage or debris ingestion
• Servicing personal watercraft and jet boats with 155.5 mm ID pump housings
• Preventive replacement before clearance exceeds specification

Good To Know

Q: How do I know the wear ring needs replacing? A: Common signs include cavitation, reduced top speed, and visible grooves or deep scoring on the ring surface. Measuring the ring-to-impeller clearance against specification confirms whether replacement is due.

Q: Does the wear ring come with mounting hardware? A: Wear rings are typically supplied as the ring itself, and any fasteners or seals should be ordered separately. Check your pump housing design to confirm the mounting method before installation.

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