Installation Guide

1. Preparation: Disconnect the fuel line and flush the engine cooling system. Gather all necessary tools including socket wrenches, screwdrivers, and a torque wrench.
2. Access the Water Pump: Remove the lower unit from the outboard to expose the water pump assembly. Refer to your engine's service manual for torque specifications and disassembly steps.
3. Remove Old Water Pump Components: Carefully extract the old impeller, housing, gaskets, and seals. Inspect the pump housing for wear or scoring that could affect the new impeller.
4. Clean All Surfaces: Thoroughly clean the mating surfaces of the pump housing and base plate. Remove any old gasket material or corrosion using a scraper and solvent.
5. Install New Water Pump Parts: Install the new housing (6E5-44311-00), insert cup (6E5-44322-00), and gaskets in the proper order. Apply marine-grade grease to the impeller (6E5-44352-01) and slide it into the housing, ensuring the key aligns correctly.
6. Secure the Plate and Hardware: Position the plate (6E5-44323) over the impeller and secure with the provided bolts (97080-08045) and pins (93606-12019). Tighten bolts in a star pattern to the manufacturer's torque specification.
7. Replace Thermostats: Locate the thermostat housings on the cylinder head. Remove old thermostats (6E5-12411-30) and gaskets (688-12414-A1), then install the new ones with fresh gaskets.
8. Install Drain Gaskets: Replace all drain plug gaskets (90430-08020) on the lower unit and powerhead. Tighten drain plugs to specification to prevent leaks.
9. Replace Fuel Filter: Locate the inline fuel filter assembly. Remove the old filter and install the new fuel filter (6F5-24563-00), ensuring proper flow direction.
10. Install Gear Oil Pump: Attach the gear oil pump (24OP149) to the lower unit drain/fill holes. Pump fresh gear oil into the lower unit until it flows from the upper vent hole, then install plugs with new gaskets.
11. Reassemble Lower Unit: Reattach the lower unit to the mid-section, ensuring the water tube seats properly into the pump housing. Torque all mounting bolts to specification.
12. Test and Inspect: Reconnect the fuel line and run the engine with a water supply (muffs or tank). Check for proper water flow from the tell-tale, inspect for leaks, and verify smooth operation.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my specific Yamaha engine?
A: Verify your engine is a V4 2-Stroke model rated at 115 HP or 130–140 HP built between 1984 and 2014. Cross-reference your existing part number (6E5-W006A-00) or use the Yamaha serial number guide linked above to confirm your engine model and year.

Q: How often should I replace these maintenance components?
A: Yamaha recommends water pump impeller replacement every 2–3 years or 200–300 hours of operation, whichever comes first. Thermostats should be inspected annually and replaced if stuck or corroded, and the fuel filter should be changed every season or 100 hours.

Q: What are the signs that my water pump or thermostat is failing?
A: Common symptoms include weak or absent water flow from the tell-tale, engine overheating, steam from the engine cover, or a high-temperature alarm. If you notice any of these signs, inspect and replace water pump and thermostat components immediately to prevent engine damage.

Q: Can I reuse the old gaskets and O-rings during installation?
A: No, always replace all gaskets, O-rings, and seals with the new ones provided in this kit. Reusing old seals can result in leaks, reduced cooling efficiency, and potential engine overheating.

Q: Is the impeller in this kit the same material as the OEM part?
A: Yes, the aftermarket impeller is manufactured from a comparable neoprene compound that meets or exceeds OEM specifications. It is produced in an ISO9002-certified facility and undergoes rigorous quality inspections.
