OPP-3

 

OPP-3

For vehicles with very little space for the propellers, we offer OPP-3 where  hydraulic motor is positioned inside the lower bulb housing, and is directly connected to the propeller shaft made of steel. Same high propulsive efficiency propellers used in OPP-2 can be used.The shaft is greased and the bulb is sealed to eliminate the need for further greasing or lubing. The steel cage around the propeller is to protect the propeller from external impacts.
