Installation Guide
- Safety First: Disconnect the engine's battery and shift the outboard into neutral.
- Lower Unit Removal: Remove the bolts securing the lower unit (gearcase) to the engine's midsection and carefully lower it.
- Access the Pump: Unscrew the bolts on the water pump housing and lift the housing off.
- Component Replacement: Remove the old impeller, gaskets, wear plate, and seals. Note their orientation before removal.
- Clean Surfaces: Thoroughly clean the mating surfaces of the housing and gearcase, removing any old gasket material or debris.
- Install New Parts: Install the new components from the kit in reverse order. Lightly grease the new impeller and insert it while turning the driveshaft clockwise to bend the vanes correctly.
- Reassemble: Reinstall the water pump housing, ensuring the gaskets are aligned. Tighten the bolts to the manufacturer's specified torque.
- Final Steps: Reattach the lower unit to the engine. Reconnect the battery and test run the engine in water, confirming a steady stream from the tell-tale port.
Troubleshooting & FAQ
Q: How do I confirm this fits my engine?
A: First, check the Compatible Engine Models table in this listing. Verify your engine's brand, model, horsepower, and year range. This kit is a direct replacement for OEM part numbers 69G-W0078-00-00 and 69G-W0078-02-00. Comparing images to your existing part can also help confirm fitment.
Q: How often should I replace the water pump kit?
A: For optimal performance and engine safety, it is recommended to inspect the impeller annually and replace the entire water pump repair kit every 1-2 years or 100-200 hours of use. This interval may be shorter if you frequently operate in sandy, silty, or saltwater environments.
Q: What are the symptoms of a failing water pump?
A: The most common signs include the engine overheating alarm activating, a weak or non-existent water stream from the "tell-tale" outlet port, or steam coming from the exhaust. Upon inspection, a worn impeller may appear cracked, brittle, or have broken vanes.

A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
