SHIFT DAMPENER SYSTEM (SDS™)
Yamaha's patent-pending Shift Dampener System (SDS™) greatly reduces the noise commonly associated with shifting gears. Using a new design and components specific to Yamaha "K" size propellers, much of the force of shifting is absorbed. Standard on Yamaha's new aluminum Talon™ series of propellers, it means smooth and quiet operation when both shifting and while in gear. Talon propellers require no special hardware for proper operation.
