Marinebaby Aluminum Motor Bracket: Heavy Duty 20 HP
Best for: Small to mid-sized boats requiring a robust aluminum mounting surface with reliable locking. This Marinebaby bracket accepts 2-stroke motors from 7.5 to 20 HP, featuring stainless steel springs for counter-balance and a solid polypropylene mounting board. The 5-position height adjustment from 195 mm to 320 mm helps tailor trim and lift for different sea states and loading scenarios.
Why selected: It combines a sturdy aluminum body with stainless springs, delivering straightforward, durable performance for auxiliary or trolling setups. The integrated height adjustability supports varying transoms and motor heights, making it versatile for many boats.
Consideration: As with all aluminum-based brackets, ensure proper corrosion protection and regular maintenance to sustain long-term performance in harsh marine environments.
Haida 2-Stroke Bracket Up To 20 HP
Best for: Boats needing a stainless steel option with strong base construction. This bracket uses 304 stainless steel, with a plastic base and a mounting footprint of 4-7/16″ by 5-11/16″. It supports up to 20 HP and requires manual lifting to raise and lower the motor, offering a basic, robust solution for smaller vessels.
Why selected: The stainless steel composition provides excellent corrosion resistance and long-term durability in saltwater environments. The straightforward design favors buyers who want a reliable, fixed-position mount with a simple operation.
Limitation: Manual lifting means no built-in electric assist; consider this if you frequently reposition the motor for docking or trolling in rough conditions.
Mojiate Stainless Steel Bracket: 20 HP
Best for: Boats requiring a heavy-duty, corrosion-resistant stainless steel bracket with multiple adjustment points. This bracket supports 2-stroke motors from 7.5 to 20 HP with a maximum weight around 110 lbs, using a spring-loaded, four-vertical-position adjustable design.
Why selected: Its reinforced welded frame and stamped stainless components provide additional strength for frequent trolling or engine positioning changes. The four-position system gives flexible trim control for varying sea conditions.
Caution: Large or heavy motors may require careful weight distribution checks and proper transom reinforcement to prevent flex over time.
Marinetech Panther 550407AL Bracket
Best for: 2- and 4-stroke motors up to 15 HP, with a focus on hard-coat anodized aluminum and reliable torsion springs. This bracket prioritizes a lightweight yet sturdy solution for mid-range powerboats and sailboats needing a secure auxiliary setup.
Why selected: The hard-coat anodized aluminum offers improved wear resistance, while stainless torsion springs aid smooth operation and secure motor positioning. The design aims for durable performance in mixed water conditions.
Limitation: Designed for motors up to 15 HP; heavier or larger engines may require a higher-capacity mounting solution.
Amarine Made Heavy Duty Bracket: 7.5–20 HP
Best for: Small to mid-sized powerboats and yachts needing a retractable, wide-track bracket for trolling or auxiliary motors. It accommodates 7.5 to 20 HP, with a 52 kg (115 lbs) maximum motor weight and a five-position spring-loaded adjustment.
Why selected: The retractable design and wide track body contribute to stability and ease of motor deployment. The reinforced welded frame and stamped stainless components provide robust construction for regular use in marine environments.
Note: Ensure the mounting footprint aligns with your transom width and motor shaft height to achieve optimal balance and control.
Buying Guide
What to consider when choosing an outboard motor bracket
- Boat type and transom size: Confirm mounting footprint and clearance for your boat’s transom and hull design.
- Motor type and weight: Select a bracket rated for your motor’s horsepower and weight to ensure secure support and trim control.
