Installation Guide

1. Disconnect the fuel line and remove the lower unit from the outboard according to your service manual. Ensure the engine is off and cool before beginning.
2. Remove the old water pump assembly by loosening the bolts securing the pump housing. Carefully extract the impeller, plate, and gaskets.
3. Clean all mating surfaces thoroughly to remove old gasket material, debris, and corrosion. Use a plastic scraper to avoid scratching metal surfaces.
4. Install the new impeller (6E5-44352-01) into the housing with blades oriented correctly (consult your service manual for rotation direction). Apply a light coat of marine grease to ease installation.
5. Position the insert cup (6E5-44322) and plate (6G5-44323-00) in the correct orientation. Ensure the key (90280-04M05) is seated properly in its slot.
6. Install new O-rings (93210-37M67 and 93210-86M38) into their respective grooves. Lubricate lightly with marine grease to prevent pinching during assembly.
7. Mount the water pump housing (6E5-44311-00) with the new gasket (6E5-44315-A0). Secure using the provided bolts (97080-08045) and pins (93606-12019), torquing to manufacturer specifications.
8. Replace the thermostats (6E5-12411-30) in both thermostat housings, using new gaskets (688-12414-A1) on each side. Ensure proper seating to prevent coolant leaks.
9. Install new drain gaskets (90430-08020) on all four drain plugs before reinstalling them. Tighten plugs securely but do not over-torque.
10. Replace the fuel filter (6F5-24563-00) in the fuel system, ensuring correct flow direction (arrow marking on filter body). Check fuel line connections for secure fit.
11. Install the cotter pin (91490-40030) in the appropriate location per your service manual. Attach the gear oil pump (24OP149) according to manufacturer instructions.
12. Reassemble the lower unit to the outboard, reconnect fuel lines, and test the cooling system by running the engine in water. Check for leaks and proper water flow from the tell-tale indicator.

Troubleshooting & FAQ

Q: How do I confirm this service kit fits my specific Yamaha engine?
A: Verify your engine's horsepower, stroke type (2-Stroke), and year against our compatibility table. Cross-reference your existing OEM part number (6G5-W006A-00) with your engine's service manual or exploded parts diagram to ensure a match.

Q: How often should I replace the water pump impeller and perform this service?
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 water or notice overheating, inspect and replace more frequently.

Q: What are the signs that my water pump or thermostats need replacement?
A: Common symptoms include engine overheating, weak or no water flow from the tell-tale indicator, steam from the engine, or an alarm sounding. Damaged impeller vanes, stuck thermostats, or worn gaskets are typical causes.

Q: Can I use this kit in saltwater environments?
A: Yes, all components are suitable for saltwater use. However, flush your cooling system with fresh water after each saltwater outing and inspect components regularly to maximize service life and prevent corrosion.

Q: Do I need any special tools to install this service kit?
A: Basic hand tools (socket set, screwdrivers, torque wrench) and a lower unit removal tool are typically required. Consult your Yamaha service manual for torque specifications and detailed disassembly/reassembly procedures.
