Sierra 18-3281 Water Pump Service Kit for Honda BF25/BF30 Outboards, Replaces 06192-ZV7-000

The Sierra 18-3281 Water Pump Service Kit is a complete water pump rebuild kit engineered for Honda BF25 and BF30 outboard motors. Marine water pumps are wear items, and the impeller inside them degrades over time from heat, ethanol fuels, and dry-running, which reduces cooling flow and puts the engine at risk of overheating. This kit gives you everything needed to rebuild the pump in one job rather than sourcing individual parts separately.

Inside the kit is a replacement impeller, a water pump gasket, an impeller key, and a water pump O-ring, so the full wear-and-seal set is replaced at once for a proper rebuild. It is built and sold by Sierra, a long-established supplier of marine engine parts, and is manufactured to meet or exceed the performance of the original equipment part it replaces. The kit directly interchanges with Honda outboard part number 06192-ZV7-000.

Because low cooling flow can lead to expensive engine damage, this kit is a practical preventive-maintenance and repair purchase for Honda BF25/BF30 owners performing a scheduled water pump service or replacing a failed pump.
