Keep your 2015-2019 Yamaha 242-series—Limited, Limited S, E-Series, or the wake-hungry 242X E-Series—running smooth with cooling confidence by handling routine service in one shot. Every component in this genuine Yamaha kit is tuned for the twin 1.8 L High-Output engines, so installation is quick and worry-free.

Here’s what you’ll swap (and why it matters):

• 2 gal Yamalube 10W-40 Mineral 4W – marine-grade oil that clings to moving parts and whisks away heat during long, high-rpm pulls.

• (2) 69J-13440-04-00 oil filters – deep-pleat elements trap micro-metal other filters miss, keeping oil passages clear.

• (2) 6AP-E4451-00-00 air filters – fresh pleated media restores unrestricted airflow for crisp throttle response.

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

• (2) 6AP-R1321-10-00 stainless impellers – rebuild water-pump pressure, boosting coolant circulation for cooler running temps.

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

Tackle this swap once a season and head back to the water with engines that idle smoother, stay cooler, and power through double-up rollers without breaking a sweat.
