The "Everything Included" Solution

• Complete Internal Suite: Includes a new impeller, shaft, bearing, and the critical mechanical seals—eliminating the need to source individual pieces from Honda.
• Precision Machined Shaft: Features a hardened steel shaft designed to resist the pitting and scoring that causes premature seal failure.
• High-Flow Impeller: Optimized vane geometry ensures consistent coolant circulation, even at low-RPM idling in city traffic.
• OEM-Spec Seals: Includes the essential mechanical seal and oil seal to prevent coolant-to-oil contamination, protecting your engine’s bottom end.

Comprehensive Fitment Guide

This kit is a direct fit for the 250cc liquid-cooled 4-stroke (172mm) engine, commonly known as the CN250:

Mechanic's Installation Tip: When installing the mechanical seal, never touch the ceramic face with your bare fingers. Oils from your skin can cause "hot spots" that lead to immediate failure. Use a small amount of dish soap as a lubricant for the rubber seat to ensure it slides into the housing without tearing.

Note: This kit is for the internal water pump components. Please verify your exterior housing matches the CN250 design before ordering.
