Answering the need for a sturdy, adjustable mounting solution, this guide highlights five reliable outboard motor mounting boards. These brackets are best for small to mid-sized boats, inflatable craft, kayaks, and dinghies that require secure engine support without a full transom overhaul. Each option targets different users—from casual weekend anglers to hobbyists who value adjustable height and heavy-duty construction. Below is a quick comparison table to help you pick the right model at a glance.
| Product | Best For | Key Benefit | Limitations |
|---|---|---|---|
| Marinebaby Boat Outboard Motor Bracket | Small to mid-size outboard engines (2-stroke, 7.5-20 HP) | Heavy-duty aluminum frame with 5-position height adjustment | Requires mounting board compatibility with your hull |
| Alomejor Transom Mounting Plate | Inflatable boats, kayaks, dinghies, inflatables | Easy to install, PVC mounting pad for lightweight use | Best for lighter setups; not for heavy 2-stroke or 4-stroke engines |
| Universal Transom Trolling Motor Mounting Bracket | Troll motors on boats with a flat stern surface | Quick-release, simple 4-hole installation | Not suitable for outboard engines |
| Mojiate 2 Stroke Marine Outboard Motor Support | 2-stroke engines 7.5-20 HP | Heavy-duty aluminum frame with adjustable height | Not recommended for 4-stroke motors |
| YaeMarine 7.5-20hp Heavy Duty Bracket | Small to mid-sized powerboats and yachts | Anodised aluminium, robust mounting board | Mounting dimensions may require hull fit confirmation |
Selecting the right mounting board depends on motor type, boat size, and how often you need to raise or lower the engine. The following sections detail five top picks and explain who should choose each option, including practical cautions to consider before purchase.
Marinebaby Boat Outboard Motor Bracket Review
The Marinebaby Motor Bracket is built for 2-stroke motors from 7.5 HP to 20 HP. It features a heavy-duty aluminum frame with stainless steel springs that help counter-balance motor weight. The solid polypropylene mounting board provides a rigid base for stable operation. A 5-position height adjustment range (195mm to 320mm) helps tailor motor height to boat load and planing needs.
Best for: small to mid-sized boats that require a durable, adjustable system without frequent motor removal. Choose this if you want solid construction and a wide height range for different load conditions.
Caution: Ensure your hull has compatible mounting geometry and that the mounting board clears engine components at all selected heights. Heavy motors will test the brackets during rough seas.
Alomejor Transom Plate For Inflatables
The Alomejor transom mounting plate is designed for inflatable boats, kayaks, canoes, and dinghies. It emphasizes easy installation with a PVC mounting pad and a compact size (about 29.8×9.2×2.2 cm). This unit is best for lightweight outboard setups and simple retrofits on smaller craft.
Best for: casual boaters using inflatables or small craft who want a straightforward mounting option without bulk. Avoid this if you require heavy-duty support for larger engines.
Caution: It is most compatible with lightweight motors; check your engine weight and mounting surface before purchase to avoid overloading the plate.
Universal Transom Trolling Motor Bracket
This mounting bracket is designed for clamp-on electric trolling motors, not outboard engines. It provides a quick-release mechanism for easy installation and removal, with straightforward 4-hole mounting on flat stern surfaces. It is ideal for trolling motor users who want to swap mounts quickly for maintenance or different boats.
Best for: boaters who primarily use trolling motors and need a lightweight, easily removable mount. Not suitable for outboards or heavy power setups.
Caution: Not compatible with traditional outboard engines; ensure your motor type matches the product’s application.
Mojiate 2 Stroke Outboard Bracket
The Mojiate 2 Stroke Outboard Motor Stand is designed for engines 7.5 HP to 20 HP, with a maximum weight of 52 kg (115 lbs). It combines a reinforced welded aluminum frame with heavy-duty stainless steel springs and a solid plastic mounting board. A 5-position adjustable height helps with motor balance and positioning on the transom.
Best for: boaters with lightweight to mid-sized 2-stroke engines who value durability and a straightforward height adjustment. Choose this if you need a robust, long-lasting mounting board for regular use.
Caution: Not recommended for 4-stroke engines; verify engine type and mounting surface compatibility before purchase.
YaeMarine 7.5-20hp Heavy Duty Bracket
The YaeMarine bracket supports 2-stroke motors in the 7.5-20 HP range with a maximum weight around 52 kg (115 lbs). It uses anodised aluminium construction and a solid polypropylene mounting board. The lift range extends up to 340 mm, enabling solid control of motor height for different boat designs.
Best for: smaller powerboats and yachts needing a robust, corrosion-resistant mounting solution with flexible height. Consider this if you value a high lift range and durable materials.
Caution: Confirm the exact mounting footprint on your boat to ensure the holes align with your transom and that the board can clear the hull structure when raised to maximum height.
Buying Guide: Key Considerations For Outboard Motor Mounting Boards
What engine type and HP rating is supported? Choose a mounting board that explicitly supports your engine type (2-stroke vs 4-stroke) and horsepower. Overloading a board can compromise safety and stability.
Is the mounting plate compatible with your hull? Confirm mounting hole patterns, board dimensions, and clearance around the motor to avoid interference with the transom, splash well, or trim mechanisms.
How adjustable should the height be? If you frequently adjust trim, tide, or water conditions, a 5-position or more height adjustment helps maintain optimal propeller depth and balance.
Material durability and corrosion resistance: Aluminum frames with stainless steel components resist saltwater exposure and heat. Look for anodised or powder-coated finishes for longevity.
Installation complexity: Some options require drilling four holes and mounting hardware, others rely on quick-release systems. Consider your DIY comfort and tool availability.
Weight and portability: Heavier brackets provide stability but can be harder to install or switch boats. Lighter models simplify on-water changes but may compromise load capacity.
FAQ
- Can I use these brackets on any boat?
These brackets are designed for small to mid-sized boats and are most compatible with flat stern transoms or inflatable craft. Verify hull fitment before purchase.
- Do these mounts require professional installation?
Most require basic drilling and mounting hardware. If your hull needs substantial reinforcement or you are unsure, seek guidance from a marine technician.
- What motor types are supported?
Many options target 2-stroke engines in the 7.5-20 HP range. Some products are not suitable for 4-stroke motors; check the product specs carefully.
- Are there safety cautions to follow?
Ensure the mounting board is firmly secured and that the motor does not collide with the boat or water intake at various heights. Regularly inspect hardware for corrosion or wear.
- How do I choose between a heavy-duty or lightweight bracket?
Heavy-duty models are better for frequent use and higher engine weight, while lightweight options work well for inflatables or temporary setups.
- What maintenance is recommended?
Rinse with fresh water after saltwater use, inspect mounting bolts and springs, and lubricate moving parts to prevent rust and ensure smooth operation.
