Camoo MJ-1-DP Jack Plate 4” Setback
The Camoo MJ-1-DP is designed for clamp-on outboard motors up to 35 HP, with a wooden mounting block included for a precise fit. It extends 4 inches off the transom, creating a higher mounting position to improve performance on small boats with shorter shaft transoms. Best for shore-ready skiffs or inflatable craft that run lightweight low-hp motors. The wooden block reduces installation variance and helps ensure stability. A potential limitation is the added weight from the wood block and cast aluminum construction, which can affect weight-sensitive rigs.
Who it’s best for
- Boat owners with engines up to 35 HP
- Owners needing a quick, solid 4″ setback and a pre-fitted wooden block
Why selected
- Simple, sturdy design
- Includes mounting block for a precise fit
- Optimal for small, light boats and short-transom setups
Caution
Wood mounting block included can require careful moisture management and periodic inspection for wear over seasons.
VELCKING MJ-1-DP Jack Plate (Black)
The Velcking MJ-1-DP provides adjustable engine height from 0 to 100 mm in 20 mm increments, catering to tuning performance and ride characteristics. It includes rubber pad mounting blocks and stainless steel screws to securely attach without damage. Made from heavy-duty hard steel alloy, this jack plate perseveres through vibration and wake impacts. Best for boaters who require precise height control and durable hardware. A potential limitation is the need to fine-tune height with on-water adjustments, which may require careful observation of engine behavior.
Who it’s best for
- Boaters who want on-the-fly height adjustments
- Ships with mid-range engines and regular rough-water use
Why selected
- Highly adjustable height for performance tuning
- Robust mounting hardware included
Caution
Ensure mounting hardware compatibility with your transom and crossmember to avoid misalignment.
TRUCFUSION 4″ Setback Jack Plate
TRUCFUSION’s 4″ setback design moves the engine away from the transom to balance weight and minimize bow rise at high speeds. The plate uses lightweight aluminum construction with corrosion resistance suitable for marine environments. The height is adjustable with a maximum vertical lift of about 7.09 inches, depending on engine weight and water conditions. This option is best for boaters seeking a noticeable balance between setback and adjustability. A limitation is that the actual lift height varies with load and speed, so field testing is advised.
Who it’s best for
- Owners needing substantial setback without heavy hardware
- Riders who want a clear, consistent platform for performance tuning
Why selected
- 4″ setback for improved ride and wake handling
- Corrosion-resistant aluminum construction
Caution
Actual lifting height depends on engine weight, speed, and water conditions; plan testing accordingly.
ONTHEFLY Adjustable Manual Jack Plate
The On The Fly jack plate features the fastest manual adjustment in its class, allowing quick motor raise and lower for better hydrodynamics on the water. It supports up to 30 HP engines and offers on-the-water adjustability, enabling changes while afloat. Best for boaters who demand rapid position changes in varied conditions. A limitation is that it supports up to 30 HP, which may exclude higher-hp setups.
Who it’s best for
- Boaters needing on-water, rapid adjustments for small motors
- Shallow-water sail or fishing setups where quick changes help
Why selected
- On-the-water adjustability
- Fast manual operation for quick responses
Caution
Limitations in engine HP mean it is not suitable for higher-hp applications beyond 30 HP.
MJ-1-DP Mini Jack Plate With 4″ Setback
The MJ-1-DP Mini Jack Plate by Bzcovac is a compact 4″ setback solution for small outboards up to 35 HP. Cast aluminum construction adds durability and corrosion resistance, with a mounting wood included for a precise fit. It is designed to optimize engine height and propeller efficiency, delivering better top speed and stability in shallow-water or shallow-transom scenarios. Best for small boats where weight and space are at a premium. A potential limitation is that it has a fixed 4″ setback, which may not suit needs requiring larger adjustments.
Who it’s best for
- Owners of Jon boats or shallow-draft craft using up to 35 HP
- Those seeking performance gains with a compact, light option
Why selected
- Compact, lightweight design with a wood mounting block
- Improved propeller efficiency and stability
Caution
Fixed setback limits future customization if you later upgrade to different hull forms or higher HP.
ElaraBerry Fixed Jack Plate 4 Inch
The ElaraBerry Fixed Jack Plate offers a durable aluminum construction with fixed 4-inch setback and height alignment to improve engine mounting. It highlights corrosion resistance and a robust load-bearing capacity, supported by multiple engine and transom mounting holes to accommodate diverse setups. Best for users seeking a stable, non-adjustable option that still improves waterline alignment. A limitation is the lack of height adjustment after installation.
Who it’s best for
- Owners preferring a fixed height solution with solid mounting
- Repower projects or simple upgrades on small boats
Why selected
- Solid aluminum construction with corrosion resistance
- Multiple mounting holes for versatile installation
Caution
Fixed height means no on-the-fly adjustments; plan placement carefully during install.
VELCKING MJ-1-DP Jack Plate (White)
The Velcking MJ-1-DP White model mirrors the black variant with adjustable height from 0-100 mm in 20 mm increments and includes rubber pad mounting blocks plus stainless steel screws for secure mounting. Its heavy-duty hard steel alloy construction adds durability for regular v-bounce and wake interactions. Best for users who want consistent height control with robust hardware. A limitation is that all adjustments require careful on-water checks to maintain correct engine alignment and trim.
Who it’s best for
- Boaters seeking durable, adjustable height control
- Rigs exposed to frequent rough-water operation
Why selected
- Adjustable height with included secure mounting hardware
- Durable material suitable for marine use
Caution
Ensure proper clearance and alignment with your transom and motor clamps to avoid binding.
Buying Guide
- What setback do you need? Most options provide 4″ setback, but check if you require more or adjustable setback for beam balance or bow lift.
- What HP does your motor have? Some models are optimized for engines up to 30-35 HP; choose accordingly to avoid over-stressing supports.
- Adjustability needs: Do you want on-water height adjustments or a fixed height? Manual vs adjustable plates affect usability on the water.
- Material and durability: Aluminum and steel alloys offer different corrosion resistance and weight profiles; consider your boating environment (saltwater vs freshwater).
- Installation considerations: Some include mounting blocks or hardware; verify compatibility with your transom and existing fittings.
Practical questions to consider
- Will you frequently adjust engine height for shallow water or different loads?
- Is your motor’s shaft length compatible with a 4″ setback on your transom?
- Do you require the ability to adjust on the water or only pre-ride setup?
- How important is weight and mounting hardware quality for your rig?
