Description

SIERRA Yamaha Water Pump Repair Kit with Housing – 18-3415

The SIERRA 18-3415 is a water-pump repair kit with housing for compatible Yamaha outboards using the 63D-series pump configuration. It packages the pump housing and key internal wear components together for a more complete cooling-system service when the housing is no longer suitable for reuse.

• Includes replacement water-pump housing and housing gasket
• Includes SIERRA 18-3069 impeller, 18-3449 insert cup, 18-3186 impeller plate and 18-3305 impeller key
• Includes SIERRA 18-1830 water-seal damper plus O-ring, bolt and washer
• Direct service alternative for Yamaha 63D-44311-00-00, 63D-W0078-01-00 and 63D-W0078-03-00 references
• Verify Yamaha engine model, model year and original pump number before installation

A complete pump service is recommended when the housing or internal wear surfaces show scoring, distortion or heat damage. Inspect the water-tube connection and sealing surfaces during installation so the rebuilt pump can maintain proper prime and cooling-water flow.
