VEPURLT Adjustable Outboard Jack Plate 4in Aluminum — Single-Bolt Vertical Adjust, 4in Setback

If your long-shaft engine sits too low on a short transom or your boat struggles to lift, trim, or accelerate properly, an adjustable jack plate can restore optimal engine height and angle. The VEPURLT jack plate is a lightweight aluminum solution with pre-drilled mounting patterns, bronze and brass hardware to reduce binding, and smooth single-bolt vertical adjustment that provides up to 4 inches of travel plus 4 inches of setback. It arrives ready to bolt on for many common outboard installations and includes a one-year manufacturer warranty against defects.

How does this jack plate help with poor holeshot and trim problems?

Raising and setting back the motor changes propeller immersion and hull trim, which can significantly improve acceleration from a standstill and optimize planing. By correcting the outboard’s angle relative to the water, you reduce ventilation and allow the prop to bite more effectively.

• Adjust up to 4 inches vertically for better prop immersion.
• 4 inches of setback moves the prop away from the transom for cleaner thrust.
• Single-bolt adjustment prevents binding and eases on-the-water tuning.
• Light 24 lb plate minimizes added weight aft of the boat.

Will this plate fit my engine and transom mounting pattern?

This jack plate includes a common pre-drilled bolt pattern intended for 1/2" stainless mounting hardware and many long-shaft outboards. If your holes do not match, the aluminum plate can be drilled to suit your boat, but modifying the unit voids returns.

• Top holes: 12 7/8" center-to-center across the top two mounting points.
• Bottom holes: 9 7/8" center-to-center across the lower mounting points.
• Vertical distance: 8" between top and bottom mounting hole centers.
• Designed for 1/2" stainless fasteners for secure attachment.

What are the build features and maintenance considerations?

The plate is fabricated from corrosion-resistant aluminum and fitted with bronze and brass components where metal-on-metal movement occurs to reduce seizing. Routine inspection and lubrication of pivot and slide points will keep the adjustment mechanism operating smoothly.

• Aluminum construction keeps the unit light at approximately 24 pounds.
• Bronze and brass bushings reduce binding at moving joints.
• Adjustment by a single steel bolt simplifies height changes and on‑water tweaks.
• Backed by a 1-year unconditional manufacturer warranty for defects.

Who is this for: The VEPURLT 4" adjustable jack plate is aimed at anglers, recreational boaters, and boat owners with long-shaft outboards mounted to short transoms who need to correct engine height and trim for improved acceleration, planing, and overall handling. It is particularly useful for those seeking a lightweight, pre-drilled retrofit that accommodates common bolt patterns and allows straightforward vertical tuning. If you routinely experience poor holeshot, require more prop immersion, or want the flexibility to test different motor heights without a permanent transom modification, this jack plate provides a practical, serviceable solution.
