Installation Guide

1. Disconnect the spark plug wire and ensure the engine is cool. Gather your tools: screwdrivers, socket set, and a drain pan.
2. Replace the oil filter: Remove the old oil filter using a filter wrench and install the new 5GH-13440-00 filter with a light coat of oil on the gasket.
3. Drain the lower unit gear oil and remove the drain screw gaskets. Install the new drain gaskets (90430-08020) on all four drain plugs.
4. Replace the fuel filters: Disconnect fuel lines and swap out the old filters with the three new fuel filters (6C5-13915-00, 6C5-24251-00, 6D8-WS24A-00) in their respective positions.
5. Service the water pump: Remove the lower unit and access the water pump housing (67F-44311-00). Disassemble the pump carefully.
6. Install the new impeller (67F-44352-00) into the housing, ensuring the vanes face the correct direction. Lubricate with water-resistant grease.
7. Replace all gaskets and seals: Use the new gaskets (688-44315-00, 688-44316-00, 688-44324-00), plate (67F-44323-00), insert cup (67F-44322-00), and O-ring (93210-46044) as you reassemble.
8. Secure the housing with the new bolts (90119-08M13 and 90119-08M87) and install the key (90280-04M04) and cotter pin (91490-40030) where required.
9. Replace the thermostat: Remove the thermostat housing cover, swap in the new thermostat (67F-12411-01), and reinstall with a new gasket.
10. Refill the lower unit with fresh gear oil using the included gear oil pump (24OP149). Pump oil into the lower drain hole until it flows from the upper vent.
11. Reassemble the lower unit to the engine, ensuring all fasteners are torqued to manufacturer specifications. Reconnect fuel lines securely.
12. Reconnect the spark plug wire, start the engine in a test tank or on muffs, and check for proper water flow from the telltale. Verify no leaks around the water pump or fuel filters.

Troubleshooting & FAQ

Q: How do I confirm this maintenance kit fits my Yamaha outboard?
A: This kit is designed specifically for the Yamaha F80B four-stroke model from 2005 onward. Verify your engine model by checking the identification plate on the transom bracket or consulting the Yamaha serial number guide linked above.

Q: How often should I replace the impeller and filters in this kit?
A: Yamaha recommends replacing the water pump impeller every 2–3 years or 200–300 hours of operation, whichever comes first. Fuel and oil filters should be changed annually or per your engine's maintenance schedule to ensure optimal performance.

Q: What are the signs that my water pump or filters need replacement?
A: Reduced water flow from the telltale (pisser), engine overheating, or erratic temperature readings indicate impeller failure. Difficulty starting, rough idling, or loss of power can signal clogged fuel filters. If you notice any of these symptoms, inspect and replace the affected components immediately.

Q: Can I install this kit myself, or do I need a mechanic?
A: If you have mechanical experience and the proper tools, you can install this kit yourself by following the service manual. However, professional installation is recommended if you're unfamiliar with outboard maintenance to avoid damaging components or voiding warranties.

Q: Does this kit include the gear oil I need for the lower unit service?
A: No, gear oil is not included. This kit provides the gear oil pump (24OP149) and drain gaskets, but you must purchase the appropriate marine lower-unit gear oil separately (typically SAE 80W-90 or as specified in your owner's manual).

A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

Q: How fast do you ship and how much does it cost?
