Ultimate Yamaha OEM 4.2L V6 Maintenance Kit – 2010+ F300 / F250 / F225 Outboard (Oil Change, Fuel Filters, Spark Plugs, Gear Lube & More)
Keep your Yamaha 4.2L V6 4-stroke outboard (F300, F250, F225 series and variants) performing at peak levels with this comprehensive, 100% genuine Yamaha OEM maintenance package. Ideal for 100-hour / annual service, seasonal prep, or winterization, this all-in-one kit covers essential oil & filter change, primary fuel filtration + water separator, spark plug replacement, lower unit gear lube service, and handy accessories – using factory-approved parts for perfect fit, superior corrosion protection, and full warranty compliance.
Why This Kit Stands Out:
- Exclusively Genuine Yamaha OEM components – no aftermarket risks to performance or coverage.
- Yamalube 4M FC-W 10W-30 marine engine oil – Yamaha-recommended conventional viscosity for excellent rust/corrosion resistance, anti-foam properties, and NMMA FC-W certification in demanding marine conditions (suitable for most climates; 20W-40 available for hotter/higher-load use).
- Includes full fuel system protection with primary filter and full-size spin-on fuel/water separator.
- 6 NGK LFR6A-11 spark plugs – factory-spec for reliable ignition and efficiency.
- Everything in one box – saves time vs. sourcing parts separately.
