Yamaha | 20 Hour Service Kit | F40 | 2008-Current

Keep your Yamaha F40 running clean and protected with a complete 20 hour service maintenance kit built around Yamalube 10W-30 FC-W outboard engine oil. Designed specifically for Yamaha F40 models produced from 2008 to current production, this kit includes the essential components required for engine oil service, lower unit maintenance, and primary fuel filtration.

The 20 hour service is an important break-in milestone that supports long-term durability and performance. Replacing engine oil and the oil filter helps remove early wear particles, while fresh gear lube and new drain gaskets help maintain proper lower unit lubrication and sealing. With everything bundled together, you can complete the service efficiently and confidently.

FAQ

Is this kit correct for all 2008 and newer Yamaha F40 models?
Yes. This kit is configured for Yamaha F40 outboards produced from 2008 onward.

Why are two lower unit drain gaskets included?
Most lower units use sealing washers at both the drain and vent screws, so both can be replaced during service.

Does this include enough oil for a complete oil change?
Yes. Three quarts of Yamalube 10W-30 meet the typical oil capacity requirements for F40 maintenance.
