Vance JJP123419 Static Jack Plate 5 inch Vertical Extension
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
If your holes do not match this configuration, you can drill into the aluminum plate. However, if you modify the unit, returns will not be accepted.
