Specifi cally and exclusively designed only for the Yamaha's XTO F375/425 outboards.

The XTO OS literally generates extreme thrust output thanks to specially-designed blades and a massive blade surface area, providing excellent

acceleration, cruising and top speed characteristics along with reduced ventilation.

XTO OS is incorporated with Yamaha's exclusive Shift Dampener System (SDS) making shifting into gear much quieter and smoother.
