The 5 INCH VERTICAL EXTENSION allows the motor to be mounted 5 inches higher than the standard mounting height on the transom. It is a must for conversion from prop to jet drive.
Another application includes mounting the 5-inch vertical extension on a hydraulic jack plate to raise the motor higher on shallow running boats that are equipped with tunnel extensions.
