Keep your 2020 Yamaha 242S or 242S E-Series in peak shape—with cooling confidence—by handling its annual tune-up in one tidy box. Each component is genuine Yamaha, matched to the twin 1.8 L High-Output engines, so you spend less time hunting parts and more time carving glassy water.

What’s inside (and why it matters)

• Two gallons of Yamalube 10W-40 Mineral 4W – marine-grade oil that clings to moving parts and carries heat away during long, high-RPM pulls.

• (2) 69J-13440-04-00 oil filters – deep-pleat media traps micro-metal debris cheaper filters miss, keeping oil passages clear.

• (2) 6AP-E4451-00-00 air filters – fresh pleated elements let the engines breathe easy for crisp throttle response and smooth idle.

• (8) NGK LFR6A spark plugs – factory-gapped for instant, reliable ignition after winter lay-ups.

• (2) 6AP-R1321-10-00 stainless impellers – restore full water-pump pressure, boosting coolant flow so temperatures stay steady on scorching afternoons.

• Disposable Yamaha funnel – keeps oil where it belongs, not in your bilge.

Swap everything in a single evening, then hit the lake knowing your 242S will run cooler, sound smoother, and power through double-ups without breaking a sweat.
