Keep your 2004-2006 Yamaha AR230 (including California editions) running smooth with cooling by swapping in everything bundled inside this factory-matched service kit. It’s the no-guesswork way to knock out an oil change, refresh your filtration, and restore water-pump flow before the next day on the lake.

What you get and why it matters

• Yamalube 10W-40 Mineral 4W – one gallon plus an extra quart for top-offs; this marine-grade blend cushions high-rev internals and helps pull heat away from moving parts.
• (2) 5GH-13440-71-00 oil filters – deep-pleat elements trap micro-debris others miss, keeping oil passages clear.
• (2) 6B6-14451-00-00 air filters – fresh pleated media lets your twin engines breathe easy, sharpening throttle response.
• (8) NGK CR9EB spark plugs – factory-gapped for crisp starts after long lay-ups.
• Starboard 68N-R1321-10-00 & Port 6B5-R1321-00-00 impellers – renew water-pump pressure to boost coolant flow and safeguard temps during wide-open runs.
• Disposable Yamaha funnel – keeps spills off the bilge and out of the water.

From spring commissioning to mid-season upkeep, this all-OEM kit streamlines maintenance so your AR230 stays cooler, sounds smoother, and spends more time carving wakes instead of sitting on the trailer.
