Parts Desk Insights
This kit is the right choice when you’re doing a full lower unit service on a small Yamaha outboard and want to replace the entire water pump assembly — housing included — rather than just the impeller. Replacing the housing along with the impeller makes sense when the housing shows wear grooves or corrosion, or when the engine has high hours and you want to start fresh. If your housing is still in good shape, an impeller-only replacement such as the Sierra 18-3068 or Sierra 3070 may be the more economical option. Always verify fitment against your specific engine model and serial number range before ordering.
