The MAS3200 coupler is one of the most popular ways to mate propellers to the bilge pump motors used in MATE and other ROV competitions. Our coupler is designed to do everything the MAS3200 does, but better. It installs on a motor shaft with a set screw just like the MAS3200, but we add a drive dog on the other end to positively lock the propeller in place and avoid slippage. We include the longer 10-24 screw to bolt a Octura 1250 Propeller in place. The adapter is aluminum and all the hardware is Stainless Steel.
