If you’re seeking a reliable way to raise your small outboard for shallower water, reduced cavitation, and improved planing, a transom riser (jack plate) is the right upgrade. These options are best for owners of jon boats, skiffs, and small aluminum boats with short transoms. They help position the engine higher and farther from the transom for better propulsion efficiency and easier beaching. Below are five solid choices with clear benefits and practical limits.
| Product | Setback | Lift | Best For | Notes |
|---|---|---|---|---|
| Camoo MJ-1-DP 4″ Setback Jack Plate | 4 inches | 0 | Short shaft boats needing engine up one level | Wooden mounting block included |
| Bzcovac MJ-1-DP Mini Jack Plate | 4 inches | 3 inches | Small motors up to 35 HP on jon boats | Cast aluminum, shallow-water benefit |
| LAIKOU MJ-1-DP 4″ Setback Plate | 4 inches | 3 inches | General small outboard use on shallow boats | Marine-grade, corrosion resistant |
| T-H Marine Mini Jacker | 4 inches | 3 inches | Clamp-on motors up to 35 HP | Easy install |
| Mindoub 5″ Jack Plates (Port + Starboard) | 5 inches | 0 | Shallow-water operation and jet-drive conversions | Higher mounting for tall engines |
Camoo Store MJ-1-DP 4″ Setback Jack Plate
Best for: Jon boats and small skiffs with short transoms using outboard motors up to 35 HP. This cast aluminum offset unit extends 4 inches off the transom, helping to position the engine higher for better planing and reduced spray. A wooden mounting block is included to aid installation and ensure a secure fit. Consider this option if you want a straightforward, compact lift without extra features.
Caution: The block is included, but alignment and mounting accuracy are essential for optimal operation and preventing transom stress. This model focuses on basic setback rather than added lift.
Bzcovac MJ-1-DP Mini Jack Plate
Best for: Small outboard motors 6-35 HP on jon boats and shallow-water craft. This model offers 4 inches of setback plus a 3-inch lift, improving propeller efficiency, reducing cavitation, and enhancing top speed and acceleration. Cast aluminum construction provides corrosion resistance for marine environments. It’s a strong all-around upgrade for limited transom space with a need for height and setback balance.
Limitation: As a mid-range option, it may not deliver dramatic lift for deeper water or larger engines. Ensure your transom can handle the mounting forces before installation.
T-H Marine Mini Jacker
Best for: Clamp-on outboard motors up to 35 HP on small boats seeking easy, tool-free adjustments. The Mini Jacker provides a 4-inch setback and 3-inch vertical offset, aiding quick planing and stability. It’s designed for straightforward DIY installation and reliable marine use, making it a practical upgrade for anglers and light boaters.
Limitation: While easy to install, heavy use or frequent height changes may require periodic checking of mounting hardware to avoid loosening over time.
Mindoub 5-Inch Jack Plates
Best for: Boats needing higher engine clearance and better shallow-water performance. The 5-inch lift with port and starboard options raises the motor higher than standard kits, making it suitable for jet-drive conversions or deeper trolling while maintaining balance. This choice is better for boats that regularly encounter very shallow water or require extra engine clearance.
Limitation: The pair design requires careful alignment on both transom sides and additional hardware, which may complicate installation on some transoms.
Buying Guide
Key factors to consider when choosing a jon boat transom riser:
- Engine compatibility: Confirm HP range (most of these options target up to 35 HP). Ensure your motor’s shaft height and clamp dimensions match the jack plate.
- Setback and lift balance: More setback moves the engine away from the transom, improving prop efficiency, while lift increases clearance. Choose based on water depth, hull design, and desired performance.
- Material and corrosion resistance: Cast aluminum is common and generally durable in saltwater and freshwater. Look for marine-grade alloys and protective finishes for longevity.
- Installation complexity: Clamp-on or block-mounted designs vary in ease of installation. DIY-friendly options are ideal for hobbyists, but verify mounting hardware and wood blocks compatibility.
- Weight and balance: Additional height and weight affect boat trim and handling. Ensure your transom structure can handle the added load without flexing.
- Maintenance and access: Consider ease of inspection, hardware accessibility, and whether the system allows quick adjustments without tools.
Frequently Asked Questions
- What does a transom jack plate do on a jon boat?
It raises and/or moves the engine away from the transom to improve planing, reduce cavitation, and optimize propeller efficiency in shallow water.
- What is a typical setback best for small Jon boats?
A common range is 4 inches of setback, with some models offering additional lift for better clearance in shallow water.
- Can I install a transom riser myself?
Yes, especially clamp-on or wooden-block-supported models. Follow the manufacturer’s mounting instructions and ensure proper securing hardware to prevent movement.
- Will a larger lift help in deep water?
Not always. Excess lift can cause trim imbalance or cavitation. Match lift to boat weight, engine size, and operating water depth.
- Are these compatible with jet-drive setups?
Some models support higher mountings suitable for jet drives, but always verify compatibility with your specific drive system and hull design.
