Installation Guide

1. Preparation: Disconnect the fuel line and remove the lower unit from the outboard engine following your service manual. Gather necessary tools including screwdrivers, socket set, and a torque wrench.
2. Water Pump Service: Remove the water pump housing and carefully extract the old impeller using pliers. Clean the housing thoroughly, removing any debris or old gasket material.
3. Install New Impeller: Lubricate the new impeller with water-resistant grease and install it with the key (664-44338-00) in the correct orientation. Ensure all blades face the proper rotation direction.
4. Replace Seals and Gaskets: Install the new wear plate (68T-44323-00), cup insert (63V-44322-00), water damper seal (68T-44366-00), and O-ring (93210-44398). Apply a thin layer of grease to all rubber components.
5. Reassemble Water Pump: Secure the water pump housing using the provided bolts (97080-08045) and tighten to the manufacturer's specified torque. Do not overtighten as this may damage the housing.
6. Replace Fuel Filter: Locate the fuel filter assembly and disconnect fuel lines carefully to avoid spillage. Install the new fuel filter (68T-24251-00) ensuring proper flow direction as indicated by arrows on the housing.
7. Thermostat Service: Remove the thermostat cover and extract the old thermostat. Clean the seating surface and install the new thermostat (6G8-12411-01) with the new gasket (6G8-12414-A0).
8. Replace Drain Gaskets: Install new drain gaskets (90430-08020) on all drain plugs before reinstalling them. This prevents oil leaks during operation.
9. Anode Replacement: Remove the old sacrificial anode and clean the mounting surface of corrosion. Install the new anode (68T-45251-00) and secure with the cotter pin (91490-30025).
10. Gear Oil Service: Use the included gear oil pump (24OP149) to drain old gear oil completely. Refill with fresh Yamaha-spec gear oil through the lower drain hole until it flows from the upper vent.
11. Reinstall Lower Unit: Align the lower unit with the driveshaft and water tube, then carefully slide it back into position. Secure all mounting bolts to the specified torque.
12. Final Check: Reconnect the fuel line, inspect all connections for leaks, and run the engine in a test tank or on-water to verify proper water flow from the telltale and smooth operation.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my specific Yamaha engine?
A: Check your engine's model designation and year against our compatibility table. The kit fits F6 A/B (2001-08), F8C (2001-2024), F8F (2016-2024), F9.9F (2008-2012), and F9.9J (2013-2024) models. You can also cross-reference your existing part number 68T-W006A-00 or consult your engine's service manual.

Q: How often should I replace these maintenance components?
A: Yamaha recommends performing this maintenance annually or every 100 operating hours, whichever comes first. If you operate in sandy, silty, or heavy debris conditions, consider more frequent intervals to prevent pump damage and ensure reliable cooling.

Q: What are the signs that my water pump impeller needs replacement?
A: Common symptoms include weak or no water discharge from the telltale, engine overheating, steam from the engine, or loss of power. If you notice any of these signs, inspect and replace the impeller immediately to avoid severe engine damage.

Q: Can I install this kit myself or do I need a professional mechanic?
A: If you have moderate mechanical skills and the proper tools, this maintenance can be performed at home following the service manual. However, if you're unfamiliar with lower unit removal or water pump service, professional installation is recommended to ensure correct assembly and prevent costly mistakes.

Q: Is the fuel filter included compatible with both gasoline and ethanol blends?
