Engine Information and Specifications

  •  115 FourStroke Command Thrust

    Engine Details

    The larger CT gearcase creates a bigger footprint in the water, providing more leverage to better control your boat. The larger torpedo, combined with a bigger-diameter prop, can lift a heavy boat onto plane more easily and hold it there at lower speeds without impacting top speed.
