Keep your 2018-2020 Yamaha 242X E-Series wake boat running smooth — with cooling peace of mind — by dropping in every genuine part packed into this handy service kit. Designed around the twin 1.8 L High-Output engines, each component fits like factory original, so routine upkeep feels quick and straightforward.

What’s inside (and why you’ll care):

• Two gallons Yamalube 10W-40 Mineral 4W – a marine-grade blend that clings to moving parts and whisks heat away during long, high-RPM pulls.
• (2) 69J-13440-04-00 oil filters – deep-pleat elements capture the micro-metal lesser filters miss, keeping oil passages clear.
• (2) 6AP-E4451-00-00 air filters – fresh pleated media restores unrestricted airflow for crisp throttle response and steady idle.
• (8) NGK LFR6A spark plugs – factory-gapped for quick, dependable ignition after winter lay-ups.
• (2) 6AP-R1321-10-00 stainless impellers – rebuild water-pump pressure, boosting coolant circulation for cooler running temps on scorching afternoons.
• Disposable Yamaha funnel – keeps oil where it belongs, not in your bilge.
