| VELCKING MJ-1-DP (White) | Same adjustable option with color choice | Durable, corrosion-resistant design |
| RUIANOMG MJ-1-DP | 4″ setback for long shaft compatibility | Strong cast aluminum construction |
| Bzcovac MJ-1-DP Mini | Compact, performance-focused upgrade | 3″ lift and 4″ setback for better hydrodynamics |
Note: All products listed are designed for outboard motors up to 35 HP and provide a 4″ setback in most configurations. Consider your boat type, shaft length, and mounting preferences when selecting one.
Camoo MJ-1-DP 4″ Setback Jack Plate
Designed for clamp-on outboard motors up to 35 HP, this cast aluminum offset jack plate supports short transoms on skiffs, aluminum boats, and inflatables. It extends 4″ off the transom and includes a wooden mounting block for a firm installation. Best for boaters who prefer a ready-to-install wooden block solution and a reliable mounting surface. A potential limitation is the need for a compatible long-shaft-to-short-transom setup to maximize performance gains.
Who this is best for: Small boats that need a simple, fixed 4″ setback with a wooden block for a snug fit. Ideal for anglers using short transoms with a long-shaft engine.
Why selected: It combines a solid aluminum build with an included wooden block for precise alignment, simplifying installation and reducing vibration. The 4″ setback helps improve water flow and engine height management for better acceleration and trim.
Caution: The wooden block must be cut and grooved properly for a secure mount; mismatches can reduce stability over time.
VELCKING MJ-1-DP Jack Plate Black
Key feature: adjustable engine height from 0–100 mm in 20 mm increments, with rubber pad mounting blocks and stainless screws for secure attachment. Made from heavy-duty hard steel alloy to withstand vibration, impact, and marine conditions. Best for boaters who want precise tuning of engine height to optimize performance and ride quality. A limitation is the need for careful installation to ensure proper alignment and prevent hardware damage.
Who this is best for: Boat owners who want customizable engine height for different loads or water conditions and a robust attachment system.
Why selected: The height adjustability allows tailored trim and top speed improvements, with secure mounting hardware included for a clean, reliable install.
Caution: Heavier steel construction can add weight to the transom; ensure your transom can support the plate and engine combination.
VELCKING MJ-1-DP White Jack Plate
This is the white variant of the adjustable 4″ setback jack plate with the same 0–100 mm height range in 20 mm increments. It includes secure mounting hardware and is built from durable aluminum alloy suitable for marine use. Best for boaters who want a lighter color option and the same performance benefits as the black version. Minor drawback: color may show wear and require occasional cosmetic touch-ups in marine environments.
Who this is best for: Those seeking a lighter aesthetic with the same performance features as the black version.
Why selected: It offers identical performance and adjustability with a different color, allowing customization without sacrificing function.
Caution: Cosmetic wear is more noticeable on lighter finishes over time in saltwater environments.
RUIANOMG MJ-1-DP 4″ Setback Jack Plate
Equipped for clamp-on outboard motors up to 35 HP, this cast aluminum jack plate increases hull clearance and allows long shaft engines on short shaft boats. It provides a 4″ setback, improving engine protection in shallow areas and enhancing performance. Best for dinghies, aluminum boats, and inflatables needing longer engine compatibility without extensive transom modifications. Limitation: aluminum construction may require regular inspection for corrosion in harsh water conditions.
Who this is best for: Boaters needing to mount long-shaft engines to short-transom boats while preserving performance and protection.
Why selected: The wide application range and robust aluminum build support durable, corrosion-resistant mounting for varying boat types.
Caution: Ensure proper corrosion protection and periodic maintenance in saltwater use.
Bzcovac MJ-1-DP Mini 4″ Setback Jack Plate
Optimized for outboard motors up to 35 HP, this mini jack plate enhances performance by allowing a 4″ setback and offering a 3″ lift. It is designed for small Jon boats, shallow water skiffs, and inflatable craft. Best for anglers and light-duty boaters seeking improved hydrodynamics and stability without heavy hardware. Limitation: the lighter build may require careful handling in rough conditions.
Who this is best for: Small craft operators seeking a compact, performance-focused upgrade with easy mounting.
Why selected: The combination of setback and lift provides appreciable gains in speed and efficiency for modest engine sizes.
Caution: Lightweight design may be less forgiving in rough seas or high-wake environments.
Buying Guide
What to consider when choosing a small engine jack plate:
- Confirm the plate supports engines up to 35 HP and is compatible with your shaft length and transom type.
- Decide how much setback you need (commonly 4″) and whether you want height adjustment (0–100 mm) for performance tuning.
- Cast aluminum offers corrosion resistance and lighter weight; steel alloys provide durability but add weight and may require more maintenance.
- Look for included rubber blocks, mounting screws, and wooden blocks if a wood mounting surface is preferred.
- Ensure your transom can handle additional load and that the jack plate aligns with your engine clamp and mounting pattern.
- Regularly inspect for corrosion, cracks, or loosened hardware, especially in salted water use.
- Consider models with widely available replacement parts and straightforward mounting procedures.
Frequently Asked Questions
- What is a jack plate used for on a small outboard? It raises or lowers the engine and adds setback to improve water flow, trim, and efficiency.
- Is a 4″ setback suitable for all boats? It works well for many small boats with short transoms, but verify your transom strength and clearance before installation.
- Do I need mounting hardware included? Prefer models that include rubber pads, screws, and an appropriate mounting block if you are not fabricating your own block.
- Can I install a jack plate myself? Yes, with careful measurement, proper tools, and following the manufacturer’s instructions. Consider professional help if unsure.
- Will a jack plate affect fuel efficiency? In many cases, yes, by optimizing propeller efficiency and reducing cavitation, though effects vary by setup.
- What maintenance is required? Inspect for corrosion, tightness of bolts, and wear on mounting blocks; lubricate moving components if applicable.
