Yamaha | 20 Hour Service Kit | QBL-10W30-FS-04

Make your first Yamaha XF425 service easier with a 20 hour service kit built around Yamalube 10W-30 Full Synthetic FC-W. This kit brings together the key items for early maintenance, including engine oil, oil filtration, gearcase lube, and fuel filtration. It also includes the smaller sealing and retention parts that are easy to overlook, such as the oil drain O-ring, R-type circlip, and lower unit drain plug O-rings, helping you complete the job with clean seals and fewer delays. With HD gear lube and a multi-purpose quart pump included, lower unit service is cleaner, easier, and more controlled.

FAQ

Why are O-rings and a circlip included in this kit?
These are common sealing and retention components used during service. Replacing them helps support proper fitment, clean sealing, and reliable reassembly.

Why does this kit include 3 quarts of HD gear lube?
Larger gearcases often need more fluid than smaller outboards, and the included volume helps make sure you can fill the lower unit to the proper level.

What does the 10-micron fuel/water separating filter do?
It helps trap fine debris and separate water from fuel before contaminants can reach sensitive fuel system components.

Can I reuse the quart pump?
Yes. Clean the pump after use and store it with your service supplies for your next lower unit service.
