271001236 Jet Pump Wear Ring 155.5 mm for Sea-Doo Fish Compact 170 1630 2026

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

This jet pump wear ring (155.5 mm ID), reference 271001236, is a replacement component that controls impeller-to-housing clearance in the jet pump of personal watercraft, helping maintain thrust and limit cavitation.

Overview

The Jet Pump Wear Ring (155.5 mm ID) is a replacement wear component for personal watercraft jet pump assemblies, cross-referenced to 271001236 and sized at 155.5 mm inner diameter. It holds the clearance between impeller and housing so the pump keeps building pressure instead of leaking water past the blade tips. This jet pump wear ring suits owners and mechanics servicing a pump assembly.

Built For Performance

• 155.5 mm inner diameter for accurate impeller clearance
• OEM cross-reference 271001236 for easy part matching
• Restores pump pressure lost to a worn ring
• Helps curb cavitation during hard acceleration
• Direct replacement in the original wear ring position

Fits These Machines

• for Sea-Doo Fish Compact 170 1630, 2026

On-The-Job Use

• Jet pump service on Fish Compact 170 1630 watercraft
• Recovering holeshot after impeller clearance opens up
• Pre-season pump inspection and rebuilds
• Repairs after sand or debris passes through the pump

Specs At A Glance

Good To Know

Q: What signals that a wear ring needs replacing? A: Common signs are slower acceleration, higher RPM for the same speed, and cavitation or vibration through the hull. Measuring impeller clearance against the service limit confirms it.

Q: Can this ring be fitted without removing the pump? A: Wear ring replacement is normally done with the pump assembly off the craft, since the ring seats in the pump housing around the impeller. Follow the service procedure for the specific model.

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