The PowerShroud™ Propeller Housing - Reduced reduces the width of Bixpy J-1 , J-2, and K-1 Motors to allow it to better fit through some kayaks' hulls or other tight spots. These include the Hobie® Mirage Drive well, Bonafide Dry Pod opening and FeelFree Pod opening among other kayaks.

This shroud already ships as part of your Mirage Fin Type Pedal Drive Adapter

With the PowerShroud™ Propeller Housing - Reduced option in place, the widest part of your motor will be 3.15" (80 mm).
