Yamaha | 20 Hour Service Kit | F40 / F40B | 2001-2008

Stay on schedule with your Yamaha F40 or F40B 20 hour break-in service using a complete maintenance kit built around Yamalube 10W-30 FC-W outboard engine oil. Designed for F40 and F40B models produced from 2001 through 2008, this kit includes the core components needed to refresh engine lubrication, service the lower unit, and maintain primary fuel filtration during the first major service interval.

The 20 hour service is a critical early milestone for long-term reliability. Replacing engine oil and the oil filter helps clear break-in residue, while fresh gear lube and new drain gaskets support proper lubrication and sealing in the gearcase. With everything bundled together, you can complete the service efficiently with the correct parts on hand.

FAQ

Is this kit correct for all Yamaha F40 and F40B models from 2001–2008?
Yes. This kit is configured for Yamaha F40 and F40B outboards produced within those years.

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/F40B maintenance.
