Installation Guide
- Disconnect the engine and allow it to cool completely before beginning any maintenance work. Gather all necessary tools including screwdrivers, wrenches, and a clean workspace.
- Remove the lower unit according to your engine's service manual to access the water pump housing. Carefully detach the water pump cover and set aside the old gaskets and components.
- Clean the water pump housing thoroughly, removing any debris, old gasket material, or corrosion. Inspect the housing for cracks or damage that may require additional repair.
- Install the new wear plate (663-44323-00) into the housing, ensuring proper orientation. Place the new gasket (663-44315-A0) on top of the wear plate.
- Insert the new impeller (6H4-44352-02) into the housing, rotating the blades in the correct direction of engine rotation. Install the key (90280-03024) and insert cup (663-44322-00) as specified.
- Apply the new gaskets (663-44324-A0 and 663-44316-A0) to the pump cover, then secure the cover using the provided bolts (90119-08M13 and 90119-08M34). Torque bolts to manufacturer specifications in a cross pattern.
- Replace all four drain gaskets (90430-08020) at their respective locations on the lower unit. Ensure each gasket seats properly to prevent oil leaks.
- Remove the old thermostat housing and install the new thermostat (6E5-12411-30) with the new thermostat gasket (6J8-12414-A0). Secure the housing and verify proper seating.
- Replace the fuel filter (61N-24560-00) by disconnecting fuel lines, removing the old filter, and installing the new one with proper orientation. Reconnect fuel lines securely.
- Install the cotter pin (91490-30025) at the designated location as shown in your service manual. Use the included gear oil pump (24OP149) to refill the lower unit with fresh gear oil to the proper level.
- Reinstall the lower unit onto the engine, ensuring all mounting bolts are torqued to specification. Double-check all connections, gaskets, and fasteners.
- Start the engine and check for proper water flow from the telltale indicator, verifying the water pump is functioning correctly. Inspect all work areas for leaks and proper operation.
Troubleshooting & FAQ
Q: How do I confirm this maintenance kit fits my Yamaha outboard?
A: Verify that your engine is a Yamaha 30HP 2-Stroke 3-Cylinder model manufactured between 1990 and 2016. Cross-reference your original part number (6J8-W006A-00) with the kit, and use the Yamaha Serial Number Guide linked above to confirm your engine specifications.
Q: How often should I perform maintenance using this kit?
A: Yamaha recommends water pump service every 100 hours of operation or annually, whichever comes first. The thermostat and fuel filter should be inspected during each service and replaced if showing signs of wear, corrosion, or reduced performance.
Q: What are the signs that my water pump impeller needs replacement?
A: Common symptoms include weak water flow from the telltale, engine overheating, steam from the engine, or reduced cooling efficiency. If your impeller shows cracked blades, missing pieces, or has become hard and brittle, immediate replacement is necessary.
