Yamaha | 20 Hour Service Kit | F25 | 1998-1999

Keep your Yamaha F25 performing at its best with a complete 20 hour service maintenance kit built around Yamalube 10W-30 FC-W outboard engine oil. Designed specifically for Yamaha F25 models produced from 1998 through 1999, this kit includes the essential components needed to complete your break-in oil and lower unit service.

The 20 hour service is an important early milestone that helps support long-term reliability. Replacing the engine oil and oil filter removes initial wear particles, while fresh gear lube and new drain gaskets help maintain proper sealing and lubrication in the lower unit. This bundled kit ensures you have the correct parts on hand to complete routine maintenance efficiently.
