A healthy cooling system is essential for keeping any outboard running strong, and the Yamaha F25 Water Pump Repair Kit - 61N-W0078-14-00 is built to restore that critical water flow in Yamaha F25 four-stroke engines. Over time, impellers wear down, gaskets lose their seal, and cooling efficiency drops — especially in shallow, sandy, or saltwater conditions where debris can sneak into the system. This complete kit gives you everything needed to get your pump back to factory performance.

Inside the package, you’ll find a precision-molded rubber impeller, a durable wear plate, plus the seals, gaskets, and hardware Yamaha specifies for a proper rebuild. Each part is engineered to fit perfectly, ensuring smooth water flow and reliable cooling from idle to wide-open throttle. Built with marine-grade materials, these components hold up under heat, friction, and constant water exposure — whether you’re fishing inland lakes or running tidal flats.

Key Features & Benefits:

• Direct-fit OEM kit for Yamaha F25 four-stroke outboards
• Complete package includes impeller, wear plate, seals, gaskets, and hardware
• Designed to restore factory cooling performance and prevent overheating
• Marine-grade materials resist corrosion, heat damage, and wear

Ideal Uses:

1. Restoring cooling performance during annual maintenance
2. Replacing worn components after running in sandy or silty conditions
3. Ensuring consistent cooling flow for saltwater, freshwater, and mixed-use outboards

Don’t leave your engine’s cooling to chance — a fresh water pump kit keeps your Yamaha F25 running at the right temperature and ready for the next adventure.
