Answering the demand for reliable, engine-height adjustments on small boats, this guide compares five top small engine jack plates designed for outboard motors up to 35 HP. These options suit skiffs, aluminum boats, inflatables, and dinghies seeking improved lift, clearances, and maneuverability. The right choice depends on your boat type, mounting style, and how you plan to tune engine height for optimal performance. The table below highlights core traits to consider at a glance.
| Product | Key Benefit | Best For |
|---|---|---|
| Camoo MJ-1-DP Jack Plate | 4″ setback; wooden mounting block included | Boats needing easy wood-fit mounting and set-back for short transoms |
| VELCKING Black MJ-1-DP | Adjustable height 0-100 mm; secure mounting | Rough water or wake-prone conditions; precise height tuning |
| RUIANOMG MJ-1-DP | 4″ setback; cast aluminum, corrosion resistant | Small boats needing hull clearance and durable build |
| Bzcovac MJ-1-DP Mini | 4″ setback; wood mounting option; 0-100 mm height range | Compact setups with 35 HP engines and wood-fit preference |
| ElaraBerry Fixed Jack Plate | Fixed 4″ setback; corrosion resistant; multiple mount holes | Budget-friendly, simple install; reliable alignment |
Camoo MJ-1-DP Jack Plate 4” Setback
The Camoo MJ-1-DP is designed for clamp-on outboard motors up to 35 HP and includes a wooden mounting block. It extends 4 inches off the transom, allowing a long-shaft motor to operate on a shorter transom. This jack plate is best for skiffs, aluminum boats, and inflatables needing a firm, adjustable setback with wood-fit compatibility. A potential limitation is the reliance on a wooden block, which may require careful alignment during installation.
VELCKING MJ-1-DP Black Jack Plate
The VELCKING Black MJ-1-DP offers adjustable engine height in 20 mm increments from 0 to 100 mm, with rubber pad mounting blocks and stainless steel screws for secure attachment. Built from hard steel alloy, it withstands marine vibration and wakes. It’s best for boaters who want precise height control and strong, long-term durability. A caution is that steel components may require anti-corrosion maintenance in saltwater environments.
VELCKING MJ-1-DP White Jack Plate
The white variant mirrors the black model’s adjustable height and secure mounting, offering the same 0-100 mm range and 20 mm increment steps. The color option may suit boats with lighter transom aesthetics. Best for same-use scenarios as the black version; consider maintenance frequency if exposed to sun bleaching or salt deposits.
RUIANOMG MJ-1-DP 4-Inch Setback
RUIANOMG offers a 4-inch setback with a robust cast aluminum construction, intended for clamp-mounted outboard motors up to 35 HP. It increases hull and strut clearance, enabling longer shaft motors on shorter transoms while permitting shallow-water operation for better water flow. Best for boats requiring improved engine protection and shallow-water versatility. A limitation is a potential alignment sensitivity during installation; precise mounting is crucial for optimal results.
MJ-1-DP Mini Jack Plate By Bzcovac
The Bzcovac MJ-1-DP Mini Jack Plate targets small-engine setups with 4″ setback and a 0-100 mm height range. It includes mounting wood and emphasizes performance optimization by raising the motor to reduce drag and cavitation while increasing top speed and acceleration. Best for 6-35 HP small boats seeking a balanced upgrade with wood mounting compatibility. A limitation is the need for careful installation to ensure wood blocks fit perfectly in some transom designs.
ElaraBerry 4 Inch Fixed Jack Plate
ElaraBerry offers a fixed 4-inch setback with corrosion-resistant aluminum construction and multiple mounting holes. It provides a straightforward installation and solid engine alignment, ideal for budget-conscious buyers who want a durable, low-maintenance jack plate. Best for simple, reliable performance without the need for height adjustability. A caveat is the lack of height adjustment after installation; plan for a fixed engine position upfront.
Buying Guide
What should you consider when choosing a small engine jack plate?
- Engine compatibility: Most options target outboard motors up to 35 HP. Confirm your motor’s shaft length and horsepower tolerance before selecting a plate.
- Setback vs. height adjustability: If you need to clear longer shafts on short transoms, seek 4″ setback options. For dynamic tuning, select models with 0-100 mm height adjustment.
- Mounting method: Wood mounting blocks simplify installation on boats using wooden transoms. Rubber pads and stainless screws provide secure crossmember mounting for metal transoms.
- Materials and corrosion resistance: Cast aluminum and hard steel alloys offer durability, while solid aluminum is highly resistant to corrosion in marine environments.
- Maintenance and installability: Fixed plates are simpler and cheaper but lack adjustment. Adjustable plates require careful alignment, especially for deeper water or wake conditions.
FAQ
- Q: Do these plates fit all small boats? A: They fit many small boats with clamp-on motors up to 35 HP, but always verify transom dimensions and shaft length compatibility.
- Q: Is height adjustment necessary? A: Adjustment helps optimize trim, speed, and fuel efficiency, especially for boats with long-shaft engines on short transoms.
- Q: What about wood mounting blocks? A: Wood blocks aid installation on wooden transoms but require precise fitting and periodic inspection for wear.
- Q: Which material lasts longest in saltwater? A: Cast aluminum and solid aluminum constructions generally offer excellent corrosion resistance in marine environments.
- Q: Should I choose fixed or adjustable? A: Choose fixed for budget simplicity; choose adjustable if you frequently operate in varying depths or water conditions.
- Q: Can these affect hull performance? A: Yes, proper setback and height alignment reduce cavitation, improve propeller efficiency, and enhance hull clearance.
