Yamahas new family of XTO OS Propellers are made to complement the torque potential of the Yamaha XTO.
Thanks to the new Thrust Enhancing Exhaust Routing, XTO OS propellers bite clean water in reverse, which helps yield reverse thrust up to 300 percent of that developed by Yamahas F350.
But the new props play a role themselves, with large diameters and increased blade surface area. They are designed for moving really big boats. With new stainless steel material, they are also more resistant to corrosion and surface discoloration, too.
