Give your 2018–2021 Yamaha 210 FSH Deluxe a thorough once-over with cooling confidence by swapping in every OEM part from this all-in-one service kit. It’s tailored for the single 1.8 L engine, so you can breeze through maintenance and be back on the water in no time.

What’s inside (and why you’ll appreciate it):

• 1 gal Yamalube 10W-40 Mineral 4W + 3 quarts – marine-grade oil that clings to bearings and wicks heat away during high-RPM runs.

• (2) 5GH-13440-80-00 oil filters – deep-pleated media snags micro-metal debris that bargain filters miss, keeping oil passages clear.

• (2) 6EY-14451-00-00 air filters – fresh pleated elements restore unrestricted airflow for crisp throttle response and smoother idles.

• (6) NGK CR9EBSpark plugs – factory-gapped for instant, reliable sparks after winter lay-ups or marathon cruises.

• (2) 6EY-R1321-01-00 stainless impellers – rebuild water-pump pressure to boost coolant flow, so your engine stays comfortably cool.

• Disposable Yamaha funnel – keeps oil changes neat—no slicks in the bilge or on your deck.

Swap these components each season to enjoy cooler running temps, snappier acceleration, and the peace of mind that comes from using parts designed by the same engineers who built your boat.
