Propeller (SDS)
The optional Shift Dampener System (SDS) uses a damper “1” to reduce the shock when the out-
board motor is shifted into gear, and eliminates the clunk that is sometimes heard.
When shifting gears, the protrusions “a” on the dedicated spacer “2” transmit the rotational force of
the propeller shaft directly to the propeller “3”.
