Installation Guide
- Disconnect the battery and flush the cooling system. Remove the lower unit according to your service manual.
- Locate and remove the water pump housing by unscrewing mounting bolts. Note the orientation of all components.
- Remove the old impeller, gaskets, seals, and wear plate. Inspect the pump housing for corrosion or damage.
- Clean all mating surfaces thoroughly using a gasket scraper and suitable solvent. Ensure no debris remains.
- Install new oil seals (93101-23070) into the housing using a seal driver. Ensure they are seated evenly.
- Place the new wear plate (6CJ-44323-00) onto the housing with the smooth side facing the impeller. Apply marine grease to the plate.
- Lubricate the new impeller (6H3-44352-00) generously with marine grease. Install it with blades oriented in the correct rotation direction.
- Install the insert cup (63D-44322-00) and grommet (663-44366-00). Position new gaskets (6CJ-44315-00, 6CJ-44316-00, 6CJ-44324-00) on mating surfaces.
- Install the cover (63D-44312-00) and secure with new bolts (90119-08M14 and 90119-08M33). Torque to manufacturer specifications.
- Replace the thermostat (6G8-12411-00) with its gasket (62Y-12414-00). Install fuel filters (6C5-13915-00, 6D8-WS24A-00, 6C5-24251-00) and oil filter (5GH-13440-60).
- Reinstall the lower unit, ensuring proper alignment and using new drain gaskets (90430-08020). Torque all fasteners per specifications.
- Reconnect the battery and run the engine in a test tank. Verify strong water flow from the tell-tale and check for leaks.
Troubleshooting & FAQ
Q: How do I confirm this kit fits my Yamaha engine?
A: This kit is designed for Yamaha 70HP 4-Stroke engines manufactured between 2011 and 2022. Verify your engine's model year and cross-reference the OEM part number 6CJ-W006A-00 with your service manual or exploded parts diagram before ordering.
Q: How often should I replace the water pump?
A: Yamaha recommends inspecting the water pump annually and replacing the impeller every 2–3 years or 200–300 hours of operation, whichever comes first. If you operate in sandy, silty, or debris-filled water, consider more frequent replacement.
Q: What are the signs of a failing water pump?
A: Common symptoms include weak or absent water flow from the tell-tale (indicator stream), engine overheating, steam from the engine, reduced performance, or an overheat alarm. If you notice any of these signs, inspect the water pump immediately.
Q: Does this kit include the thermostat and filters?
A: Yes, this comprehensive maintenance kit includes one thermostat (6G8-12411-00), three fuel filters (6C5-13915-00, 6D8-WS24A-00, 6C5-24251-00), one oil filter (5GH-13440-60), and a gear oil pump (24OP149), in addition to all water pump components.
Q: Can I install this kit myself or do I need a mechanic?
A: Installation requires mechanical aptitude, proper tools, and familiarity with outboard lower unit disassembly. If you have experience with marine engine maintenance and follow the service manual, DIY installation is feasible. Otherwise, professional installation is recommended to ensure correct torque specifications and proper assembly.
