Installation Guide

1. Preparation: Disconnect the fuel line and remove the lower unit from the outboard. Clean the pump housing thoroughly to remove old gasket material and debris.
2. Remove Old Components: Carefully extract the old impeller, gaskets, and seals from the water pump housing. Inspect the housing for cracks or excessive wear.
3. Install New Plate and Insert Cup: Position the new plate (688-44323-00) and insert cup (688-44322-00) into the housing base. Ensure proper alignment with mounting holes.
4. Lubricate and Install Impeller: Apply marine grease to the new impeller (688-44352-00) and gently rotate the vanes in the correct direction as you slide it into the housing. Use the key (90280-04M04) to secure impeller position on the drive shaft.
5. Install Gaskets and O-Ring: Place gaskets (688-44315-00, 688-44316-00, 688-44324-00) in their respective positions. Install the O-ring (93210-46044) ensuring it seats properly in its groove.
6. Replace Thermostat Assembly: Install the new thermostat (6E5-12411-30) with its gasket (688-12414-A1) into the thermostat housing. Ensure the thermostat is oriented correctly per factory specifications.
7. Install Drain Gaskets: Replace all four drain gaskets (90430-08020) at their respective drain plug locations.
8. Secure with Fasteners: Tighten bolts (90119-08M13 and 90119-08M16) in a cross-pattern to manufacturer torque specifications. Insert the cotter pin (91490-30025) through the appropriate securing point.
9. Replace Fuel Filter: Install the new fuel filter (655-24560-00) in the fuel line, ensuring proper flow direction indicated by arrows on the filter body.
10. Install Gear Oil Pump: Attach the gear oil pump (24OP149) according to your engine's maintenance manual.
11. Reassemble Lower Unit: Carefully reinstall the lower unit, reconnect fuel lines, and refill with fresh gear oil.
12. Test Operation: Start the engine in a test tank or on-water and confirm strong water stream from the telltale outlet. Monitor engine temperature during initial run.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my specific Yamaha engine?
A: Verify your engine is a Yamaha 2-stroke rated between 75HP and 90HP manufactured between 1984 and 2011. Cross-reference the OEM part number 692-W006A-00 with your engine's parts diagram using the Yamaha catalog link above, or check your existing water pump housing for stamped part numbers.

Q: How often should I replace my water pump impeller and components?
A: Yamaha recommends inspecting the water pump impeller annually and replacing it every 2–3 years or 200–300 hours of operation, whichever comes first. If you operate in sandy, silty, or debris-filled water, inspect and replace more frequently. Signs of wear include overheating, weak water stream from the telltale, or visible cracks in the impeller vanes.

Q: What are the symptoms of a failing water pump?
A: Common warning signs include engine overheating, reduced or no water flow from the telltale (indicator) outlet, steam from the engine, loss of power, and the overheat alarm sounding. If you notice any of these symptoms, shut down immediately and inspect the cooling system.

Q: Does this kit include everything I need for a complete water pump rebuild?
A: Yes, this kit contains all 16 essential components including the impeller, gaskets, seals, plate, insert cup, fasteners, thermostat assembly, fuel filter, and bonus gear oil pump. You'll have everything required for a comprehensive cooling system service.

Q: Can I install this kit myself or do I need a professional?
A: If you have mechanical experience and the proper tools, this is a manageable DIY project following the installation guide. However, incorrect installation can lead to engine damage from overheating. If you're unfamiliar with outboard lower unit service, we recommend professional installation.
