Camoo MJ-1-DP 4″ Setback Jack Plate
Best for small outboards up to 35 HP with a wooden mounting block included. It extends 4″ off the transom and is designed to work with short transom boats. This cast aluminum offset plate helps long-shaft motors fit shorter transoms, improving planing and control. The wooden block model (# WOOD0002) ensures a snug fit and reliable installation. Caution: wooden mounting components may require periodic inspection in exposed marine environments.
VELCKING MJ-1-DP 4” Setback Jack Plate
Best for adjustable engine height with secure mounting. This jack plate supports 0-100 mm height adjustments in 20 mm increments, offering tunable performance and ride characteristics. It includes rubber pad mounting blocks and stainless screws to minimize damage to the mount and crossmember. Durable hard steel alloy construction resists vibration and boating wakes, making it a solid choice for frequent rough-water use. Caution: ensure compatibility with your transom and mounting hardware before installation.
VEPURLT 4″ Aluminum Adjustable Jack Plate
Best for users seeking precise alignment with a robust mounting pattern. This jack plate is designed for pre-drilled holes and features 12 7/8″ across the top holes and 9 7/8″ across the bottom holes, with 8″ vertical spacing between hole sets. It provides 4″ of setback and 4″ of vertical movement, balancing engine height and propulsion efficiency. Bronze and brass hardware reduce binding. Limitation: actual lifting height depends on engine weight, boat speed, and water conditions, so plan for field adjustments.
TRUCFUSION Outboard 4″ Setback Jack Plate
Best for lightweight aluminum reliability with corrosion resistance. This jack plate provides a 4″ setback designed to balance weight distribution and reduce bow rise at speed, improving stability. It offers adjustable height with a maximum vertical travel of about 7.09″ when the lower bracket is fixed. Note that actual lift height depends on engine weight, boat speed, and water conditions. Choose this if you need a balance of lift and marine durability.
On The Fly Adjustable Manual Jack Plate
Best for rapid manual adjustments on the water. This unit offers the fastest manual jack plate operation, enabling quick motor height changes to adapt to conditions. It supports up to 30 HP motors and is designed for on-the-water tuning, making it ideal for anglers or recreational boaters who need immediate performance tweaks. Caution: handles up to 30 HP, so not suitable for larger engines.
MJ-1-DP Mini Jack Plate 4″ Setback
Best for compact, shallow-water setups with up to 35 HP. The MJ-1-DP Mini Jack Plate offers a 4″ setback and includes a mounting wood. It is designed to optimize hydrodynamics, reduce cavitation, and improve top speed for small jon boats, shallow skiffs, and inflatables. The lightweight, cast aluminum construction resists corrosion in marine environments. Limitation: may not fit larger engines or longer shaft configurations.
ElaraBerry 4 Inch Fixed Jack Plate
Best for a fixed mounting solution with solid aluminum construction. This fixed jack plate features 3 engine mount holes and 2 transom holes, enabling precise alignment and secure installation across multiple boat and motor setups. It offers corrosion resistance and reliable load-bearing capacity for everyday use on small boats, skiffs, and inflatables. Caution: fixed design provides less on-the-fly adjustability compared with adjustable plates.
VELCKING MJ-1-DP White 4” Jack Plate
Best for consistent performance with adjustable height. This white MJ-1-DP jack plate provides 4″ setback and adjustable height with rubber mounting blocks and stainless screws for secure installation. Built from hard steel alloy, it endures vibration and wakes for long-lasting use. Limitation: weight and height adjustments depend on engine and water conditions, so plan accordingly.
Buying Guide: Key Considerations For Choosing A Boat Motor Jack Plate
- Engine compatibility: Ensure the jack plate supports your motor’s horsepower and shaft length. Smaller motors (up to 30-35 HP) fit many of these options, but verify shaft compatibility and mounting patterns.
- Setback and height range: Decide how much setback you need to balance weight, bow rise, and cavitation. Adjustable plates offer flexibility for varying conditions; fixed plates provide predictability.
- Construction material: Aluminum jack plates are common for corrosion resistance and light weight; steel alloys add strength but may require more maintenance.
- Mounting method: Consider whether a wooden mounting block is included or if rubber blocks and stainless fasteners are supplied. Proper mounting hardware protects transom integrity.
- On-the-water adjustability: If you frequently adapt to different water conditions, prioritize plates with easy on-the-water adjustment vs. fixed or slower adjustments.
- Installation footprint: Check hole patterns, top/bottom hole spacing, and overall dimensions to ensure compatibility with your transom and stern setup.

FAQ
- What is the typical setback on these jack plates?
Most options offer about 4″ setback, with some adjustable models providing additional vertical range. - Can I install a jack plate myself?
Yes, if you have basic mechanical skills and follow the mounting instructions, but verify compatibility with your transom and engine. - Will a 4″ setback affect my boat’s trim?
Yes, setback changes engine height relative to the transom, which can influence bow rise and stability; adjust gradually and test in safe conditions. - Are these suitable for inflatables and jon boats?
Several options are designed for jon boats and inflatables; check the product’s listed compatibility before buying. - Do jack plates require maintenance?
Yes, inspect mounting hardware, lubricate moving parts as recommended, and check for corrosion or wear regularly.
