Installation Guide

1. Preparation: Gather all necessary tools and ensure the engine is cool and disconnected from the fuel supply. Work in a well-ventilated area.
2. Water Pump Service: Remove the lower unit and access the water pump housing. Replace the impeller (6H4-44352-02), wear plate, gaskets, and O-ring as a complete set.
3. Fuel Filters: Locate both fuel filters on your engine. Replace the primary filter (6D8-WS24A-00) and secondary filter (6C5-24251-00) with new units.
4. Oil Filter: Remove the old oil filter (5GH-13440-60) using an appropriate filter wrench. Install the new filter hand-tight, adding a thin layer of clean oil to the gasket.
5. Thermostat: Access the thermostat housing, remove the old thermostat (6G8-12411-00) and gasket (62Y-12414-00), then install the new components ensuring proper orientation.
6. Drain Gaskets: Replace all four drain gaskets (90430-08020) on the oil drain plugs to prevent leaks during future oil changes.
7. Anode Replacement: Remove the old anode (67C-45251-00) and clean the mounting surface. Install the new anode to protect against corrosion.
8. Lower Unit Oil: Use the included gear oil pump (24OP149) to properly fill the lower unit with fresh gear oil through the lower drain hole until it flows from the upper vent.
9. Hardware Installation: Use the included bolts, key, and cotter pin as specified during reassembly. Torque all fasteners to manufacturer specifications.
10. Reassembly: Reinstall the lower unit, ensuring all gaskets are properly seated and all fasteners are tightened to specification.
11. System Check: Reconnect fuel supply, add fresh engine oil, and run the engine in a test tank or on muffs to verify proper water flow and no leaks.
12. Final Inspection: Check all installation points for leaks, proper operation, and secure mounting. Dispose of old parts and fluids properly.

Troubleshooting & FAQ

A: Verify your engine model and year against our compatibility table. This kit fits F30HP (2009-2023) and F40HP (2009-2020) 4-stroke models. Cross-reference your existing OEM part number 6BG-W006A-00 or check your engine's service manual.
