Sierra Oil Change Kit 18-9394-1 for Yamaha F75-F115 Outboard Engines, 20W-40

The Sierra Oil Change Kit 18-9394-1 is a complete, all-inclusive service kit built for routine oil changes on Yamaha F75-F115 outboard engines. Rather than sourcing oil, a filter, and the small consumables separately, this kit bundles everything needed to perform the job in one pass: conventional 20W-40 outboard engine oil, an oil filter, a drain plug gasket, a disposable funnel, a service label, and a shop towel. The 20W-40 conventional oil formulation is specifically suited to hot temperature climates and warm water applications, making it a practical choice for boaters running Yamaha F75-F115 engines in warm regions or during summer operating conditions.

Because every component ships together, the kit is designed to remove the guesswork from a standard maintenance interval: drain the old oil, replace the gasket, install the new filter, refill with the included oil, and log the service using the provided label. Sierra manufactures this kit to meet or exceed the quality of the original equipment it replaces, giving Yamaha F75-F115 owners a straightforward, single-purchase option for keeping their outboard's lubrication system on schedule.
