Description
Static Jack Plate 5" Vertical Extension The 5-inch vertical Extension enables higher motor mounting, ideal for transitioning from prop to jet drive and enhancing shallow boat performance. 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.
Constructed of Extruded 6061-T6 Aluminum alloy. Features: Allows motor elevation by 5 inches over standard mounting height Perfect for use with hydraulic jack plates on shallow-running boats Made from durable extruded 6061 aluminum alloy for long-lasting performance Specifications: Vertical Extension Height: 5" Material: Extruded 6061-T6 Aluminum alloy

Boat Outfitting — frequently asked
- What material should marine hardware be made of?
- For most exposed hardware, 316 stainless steel is the marine standard — it resists salt corrosion far better than 304 stainless or plated steel. Marine-grade aluminum, UV-stabilized nylon, and King StarBoard are also common for non-structural fittings.
- How do I know a replacement seat or hatch will fit?
- Measure the mounting pattern (bolt spacing), the cutout or base dimensions, and any post diameter or height on the part you’re replacing. Match those to the new part’s specs — outfitting parts follow common sizes but are not universal, so confirming dimensions avoids returns.
- Do I need backing plates for deck hardware?
- For anything that takes load — grab rails, cleats, ladder steps, seat pedestals — yes. A backing plate spreads the load across a larger area of the deck or transom so fasteners don’t pull through under stress.
