Five Inch Transom Extension Plate (Static Jack Plate)

Vance Manufacturing Static Jack Plates – 5 inch Vertical Extension

The 5-inch vertical extension allows the motor to be mounted 5 or 6 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 motor mount on a hydraulic jack plate to raise the motor higher on shallow-running boats that are equipped with tunnel extensions. The extension is constructed of extruded 6061-T6 aluminum alloy ½-inch-thick aluminum. The hole pattern pre-drilled into this unit is listed below in inches:

• Pre-drilled holes for 1/2'' stainless hardware
• 12 7/8'' across the top two holes from center to center
• 9 7/8'' across the bottom two holes from center to center
• 8'' of vertical distance between the top holes and bottom mounting holes
