Camoo MJ-1-DP 4″ Jack Plate for Small Outboards
Designed for clamp-on outboard motors up to 35 HP, this cast aluminum jack plate extends 4 inches off the transom. It is compatible with skiffs, aluminum boats, and inflatables. A wooden mounting block is included to help achieve a secure, precise fit. Best for buyers who want a traditional wooden-block install and a straightforward, fixed-height mounting solution. A limitation is the fixed 4″ setback, which may not suit boats needing larger engine offsets.
VELCKING MJ-1-DP 4″ Jack Plate – Steel-Heavy Duty
This 4-inch setback jack plate supports engines up to 35 HP with an adjustable height from 0–100 mm in 20 mm increments. It includes rubber pad mounting blocks and stainless steel screws for a secure crossmember installation and uses a durable hard steel alloy. It’s best for buyers who want on-motor height adjustments and robust hardware, but may be heavier than some aluminum-only models.
On The Fly Adjustable Manual Plate
Marketed as the fastest manual jack plate, this unit raises and lowers the motor quickly and includes on-the-water adjustability for immediate performance tuning while afloat. It supports up to 30 HP motors and is ideal for boats requiring frequent height changes without leaving the boat. A potential limitation is lower maximum horsepower and a reliance on manual operation for larger engines.
VELCKING White 4″ Jack Plate
This white version mirrors the adjustable height range of 0–100 mm in 20 mm steps, and includes mounting hardware for secure installation. It targets Jon boats and inflatables needing a clean white finish and reliable performance. Best for buyers who want consistent dimensions and easy compatibility, though availability of color options may vary by stock.
Bzcovac MJ-1-DP Mini Jack Plate with Wood Mount
The MJ-1-DP Mini offers a 4″ setback with a mounting wood block included. It’s optimized for small outboard motors (up to 35 HP) and is designed to improve hydrodynamics by raising the engine and reducing propeller cavitation. This option is best for compact Jon boats needing a lighter, wood-supported installation, but it may not suit boats requiring higher power or thicker transoms.
TRUCFUSION Outboard Jack Plate
This 4″ setback transom jack plate for small engines features lightweight aluminum construction and an adjustable height up to a 7.09″ maximum designed lift. It is ideal for Jon boats needing a balance of weight savings and adjustability. A limitation is that actual lifting height depends on engine weight, boat speed, and water conditions, so users should plan for some variability in performance gains.
Buying Guide: Practical Selection Tips
What should I look for in a jack plate for a Jon boat?
Key factors include engine horsepower compatibility (typically 6–35 HP for these products), material (cast aluminum vs. steel alloy), adjustability range (height and setback), mounting style (wood block included or hardware-only), and on-the-water adjustability if you boat in changing conditions.
Which features impact performance the most?
Setback length determines propeller effectiveness and cavitation control; height adjustment affects engine trim, waterline alignment, and acceleration. For shallow-water use, a larger setback may help, while precise height adjustments can optimize speed and reduce drag.
What installation considerations matter?
Secure mounting hardware and compatibility with your transom are crucial. Wooden mounting blocks simplify wood transom installs, while stainless-steel screws and rubber pads protect crossmembers in metal installations. Ensure the jack plate supports your engine weight and shaft length.
Which options are best for on-the-water tuning?
On-The-Fly style plates offer quick adjustments without leaving the boat, ideal for varying loads or chop. If you rarely adjust height, fixed-height plates with set-back may suffice and keep installation simple.
Maintenance and longevity considerations
Durability depends on material and hardware quality. Aluminum jack plates resist corrosion, while steel alloys provide high strength. Regularly check mounting hardware, bolts, and seals to prevent water intrusion and ensure consistent performance.

Frequently Asked Questions
- What is a jack plate and why would I need one on a Jon boat?
A jack plate raises or lowers the engine and can add setback to improve propeller efficiency, hull stability, and overall handling, especially on shallow or choppy water.
- Can I install a 4″ jack plate myself?
Yes, if you have the appropriate mounting hardware and follow the manufacturer’s installation instructions. Some kits include mounting blocks or hardware for an easier setup.
- Is setback more important than engine height?
Both matter. Setback improves propeller efficiency and reduces drag, while height changes trim, handling, and cavitation. The best choice depends on your boat and typical water conditions.
- Will a jack plate fit all 4″ presets?
Most 4″ jack plates are designed for small outboards up to about 35 HP. Always confirm horsepower compatibility, shaft length, and transom thickness before purchase.
- How does on-the-water adjustment benefit performance?
On-the-water adjustments let you respond to load changes, speed, and chop, helping maintain optimal engine position without stopping the boat.
