Parts Desk Insights
Best use case: Ideal for boat owners and marine technicians servicing Yamaha V6 and XTO outboards at the 100-hour or annual interval. The XTO 425 coverage makes this kit particularly relevant for owners of larger sport fishing and express cruiser platforms running the XTO powerplant. As with all maintenance kits, confirm your engine model year and serial number against the 8M0224553 fitment list before ordering — Yamaha service kit compatibility can vary across production years. Contact us for volume pricing if servicing a multi-engine vessel or a fleet.
