Camoo MJ-1-DP Jack Plate 4” Setback
Best for clamp-on motors up to 35 HP on small or mid-sized jon boats and inflatables. This cast aluminum offset jack plate extends 4″ off the transom and includes a pre-cut wooden mounting block for a secure fit. Suitable for short-transom vessels requiring a longer shaft alignment. Caution: wooden block fit may require precise trimming for a snug fit and long-term reliability.
Bzcovac MJ-1-DP Mini Jack Plate with 4″ Setback
Best for small outboards (6-35 HP) on jon boats, inflatables, and aluminum skiffs. Features 4″ setback to move the engine away from the transom, plus a 3″ vertical lift to reduce cavitation and improve top speed. The cast aluminum construction offers corrosion resistance. Limitation: performance gains depend on engine weight and water conditions.
T-H Marine Mini Jacker
Best for DIY installers who want a clamp-on solution for up to 35 HP. It provides a 4″ setback and a 3″ vertical offset, enabling quicker planing and improved stability. Caution: clamp-on designs may require careful alignment and re-tightening after use in rough water.
TRUCFUSION Outboard Jack Plate
Best for lightweight aluminum craft needing a balance of weight and rigidity. It features a 4″ setback and adjustable height, designed for small engines up to 35 HP. Limitation: actual lifting height depends on engine weight, boat speed, and water conditions; verify mounting clearance before purchase.
VELCKING MJ-1-DP Jack Plate
Best for boats needing reliable, adjustable 4″ setback and height control with a white finish. Includes mounting hardware for straightforward installation. Caution: finish color may vary between batches; check for any visible cosmetic flaws upon receipt.
Buying Guide: Mini Jack Plates for Jon Boats
What should you consider when choosing a mini jack plate for a small outboard on a jon boat?
- Engine compatibility: Ensure the plate supports engines up to 35 HP and matches your shaft length requirements.
- Setback and lift: A 4″ setback helps reduce cavitation and bow rise; a 3″ vertical offset improves propeller efficiency. Pick combinations that fit your boat’s transom height and water conditions.
- Construction material: Cast aluminum resists corrosion and offers durability in marine environments; steel variants are typically heavier and may require more maintenance.
- Mounting method: Clamp-on versus wooden/mounting block setups affect ease of install and long-term rigidity. Wooden blocks can help fit deviations but require sealant and periodic checks.
- Weight and ease of installation: Lighter aluminum plates are simpler to install but verify clearance for engine tilt and steering hardware.
- Maintenance: Look for corrosion-resistant coatings and hardware; check mounting bolts and rubbers for wear after exposure to saltwater.
FAQ
- Q: Do mini jack plates work on inflatable boats? A: Yes, when the transom and engine are within the plate’s supported range and mounting is secure.
- Q: Is 4″ setback always better? A: It improves engine position relative to the water and can reduce bow rise, but effectiveness depends on boat weight, engine size, and hull design.
- Q: Can I install these myself? A: Many are designed for DIY installation with clamp-on or wooden block setups, but follow the manufacturer’s instructions and use proper sealant and hardware.
- Q: Will higher height affect steering? A: Yes, increasing engine height can change trim and steering effort; adjust steering linkage accordingly and test in calm water.
- Q: What maintenance is needed? A: Regular checks for loose bolts, corrosion on aluminum, and integrity of mounting blocks or rubber pads.
- Q: Do these increase top speed? A: They can improve planing and efficiency by reducing drag and optimizing propeller immersion, though results vary by hull, weight, and water conditions.
