Marinebaby Heavy-Duty Aluminum Motor Bracket
This bracket is designed for 2-stroke motors ranging from 7-1/2 HP to 20 HP and uses a heavy-duty aluminum frame. It includes stainless steel springs for counter-balance and a solid polypropylene mounting board. The 5-position height adjustment (195 mm to 320 mm) allows precise motor positioning, which can improve balance and performance on smaller craft. Best for boats needing reliable, rigid support with adjustable height for compact engines. Consider this if you want robust construction and a straightforward mounting solution for 2-stroke motors on dinghies or inflatable boats.
Caution: Ensure the mounting board size fits your stern or transom area and confirm mounting hole compatibility with your boat’s transom configuration. This bracket is optimized for lighter to mid-weight 2-stroke engines.
Alomejor Transom Mounting Plate For Inflatable Boats
This mounting plate is designed for inflatable boats, kayaks, canoes, and dinghies. It uses a PVC transom mounting plate that offers straightforward installation and ease of use. The compact size (about 29.8 x 9.2 x 2.2 cm) makes it suitable for tight stern spaces where a large bracket would not fit. This option is best for inflatable craft and boat types requiring a simple, lightweight solution to hold a small outboard. Best for casual day boating and for those prioritizing easy setup.
Limitation: Not ideal for heavy-duty or long-term mounting on larger powerboats. Check boat stern dimensions to ensure a proper fit.
Universal Transom Trolling Motor Mounting Bracket
Designed for clamp-on electric trolling motors, this universal bracket fits boats with a flat stern area large enough for a mounting pole. It is not intended for larger outboard engines. The bracket provides a quick-release feature for rapid motor removal for maintenance or storage. Best for kayaks and small craft using electric trolling motors. Choose this if you expect frequent motor removal or swaps in and out of boats with flat sterns.
Caution: Not compatible with outboard engines. Ensure your boat has a suitable flat stern area and sufficient space for installation and safe operation.
Mojiate 2 Stroke Outboard Motor Bracket
This 7.5–20 HP bracket targets 2-stroke engines and features a heavy-duty welded aluminum frame with stainless steel springs and a solid plastic mounting board. It offers a 5-position height adjustment to optimize motor position and balance. Best for small to mid-sized boats seeking a rugged, purpose-built mount with reliable lift and balance. It is not recommended for 4-stroke motors, so verify your engine type before purchase.
Limitation: Optimized for 2-stroke motors; not suitable for 4-stroke engines or heavier setups beyond the stated range.
YaeMarine 7.5hp-20hp Heavy-Duty Bracket
With an anodised aluminium construction and a solid polypropylene mounting board, this bracket supports 7.5–20 HP two-stroke engines up to 115 lbs. It lists precise dimensions for the mounting area, making it easier to compare against stern space. Best for compact boats needing a robust, corrosion-resistant mount that maintains engine height and balance. A good balance between strength and weight for frequent engine adjustments.
Caution: Ensure the mounting holes align with your boat transom and that the mounting area on your stern can accommodate the specified dimensions and lift range.
Buying Guide
What should I consider when choosing an outboard motor mounting board?
Engine compatibility matters most. Confirm HP range, weight, and whether the bracket supports 2-stroke or 4-stroke motors. Check the mounting board material (aluminum and polypropylene offer rigidity and corrosion resistance) and the lift range to ensure proper engine height for trim and balance.
How much weight can the mounting board support?
Look for the stated maximum horsepower and weight. Overloading a bracket can compromise mounting integrity and boat handling. For 7.5–20 HP motors, choose a bracket with a heavy-duty frame and reliable springs.
Is installation critical for performance?
Yes. Many brackets require drilling holes and secure mounting to the transom. Ensure compatibility with your boat’s stern design and use proper hardware to avoid loosening during operation.
What about maintenance and removal?
Some brackets offer quick-release or easy removal features, which are advantageous for maintenance or storage. Consider whether you’ll frequently remove the motor or swap brackets across boats.
Which features improve usability?
Five-position height adjustment helps tailor motor position to water conditions and crew weight. Anodised or corrosion-resistant materials extend lifespan in saltwater. A solid mounting board improves stability and reduces vibration.
