These products are suitable for anglers, small-powerboat owners, and sailing enthusiasts who need dependable, corrosion-resistant brackets to mount auxiliary motors. Selecting the right bracket depends on motor type (2-stroke vs 4-stroke), mounting dimensions, weight capacity, and ease of adjustment. Use the table and descriptions below to determine which bracket aligns with your boat, engine, and planned voyages.
Marinebaby Boat Outboard Motor Bracket
Features: Heavy duty aluminum construction suitable for 2-stroke motors from 7.5 HP to 20 HP; stainless steel springs used for counter-balance; solid polypropylene mounting board; 5-position locking height adjustment from 195 mm to 320 mm.
Best for: Boat owners needing a robust, adjustable mount for up to 20 HP with smooth vertical positioning. This bracket balances motor weight with a simple height range for varying load and trim conditions.
Why selected: It combines durable aluminum with a practical height adjustment, offering reliable support while keeping weight manageable for medium-sized boats.
Caution: Aluminum brackets can be sensitive to impact—avoid careless handling near hard surfaces to prevent denting or bending.
2 Stroke Outboard Kicker Bracket (Haida)
Features: 304 stainless steel construction; plastic base; mounting size 4-7/16″ x 5-11/16″; roller size 8-1/4″ x 10-3/8″; HP rating up to 20 HP; manual lifting.
Best for: Sail or powerboat setups where corrosion resistance and straightforward manual operation are priorities. This bracket suits compact auxiliary motors needing sturdy, stainless support.
Why selected: Stainless steel construction offers corrosion resistance in saltwater environments, and the compact base fits tight transoms commonly found on smaller vessels.
Caution: Manual lift requires effort; consider your preferred mounting height and exercise caution during raising and lowering in rough seas.
Mojiate Auxiliary Stainless Steel Bracket
Features: Marine-grade stainless steel; spring-loaded, four-vertical-position adjustable bracket; plastic base; mounting size 8″ × 8-5/8″; broad size 8-1/4″ × 10-3/8″; 304 stainless steel thickness 2.5 mm; supports up to 110 lbs (50 kg); reinforced welded frame.
Best for: Boats needing high-strength stainless steel support with multiple adjustable stops for 2-stroke motors around 7.5–20 HP.
Why selected: The reinforced welded frame and stamped stainless components deliver a robust mounting option with multiple positions to fit varying transom heights.
Caution: Ensure precise mounting size compatibility with your transom to avoid misalignment or motor sway at higher speeds.
Marinetech Panther Aluminum Bracket
Features: Designed for 2- and 4-stroke motors up to 15 HP or 132 lbs; hard-coat anodized aluminum; stainless steel torsion springs.
Best for: Smaller boats or lighter motor setups where a corrosion-resistant aluminum bracket with lightweight design is preferred.
Why selected: The hard-coat anodized finish provides extra protection against wear, and the stainless torsion springs help with smoother motor operation.
Caution: Aluminum brackets are typically lighter and may experience more flex under heavy loads—verify weight limits and secure mounting in rough water.
Amarine Made Heavy Duty Aluminium Bracket
Features: Retractable bracket for trolling auxiliary motors on power and sailboats; heavy duty with reinforced welded frame and stamped stainless components; suits 2-stroke motors 7.5–20 HP; maximum weight 115 lbs; five vertical positions; wide track body for added stability.
Best for: Boats needing a retractable, high-stability solution for larger auxiliary motors within a 7.5–20 HP range, particularly for trolling and trailering scenarios.
Why selected: The retractable design and wide track increase stability and reduce motor sway, which is valuable for extended trolling sessions or higher seas.
Caution: Retraction mechanisms should be inspected regularly; ensure proper latching to prevent unintended deployment in rough water.
Buying Guide
What mounting material should I choose?
Stainless steel brackets deliver superior corrosion resistance in saltwater environments. Aluminum brackets are lighter and can be suitable for smaller engines, but may require more care to prevent wear. Assess your boat’s typical operating environment and weight needs.
How do I match HP rating to a bracket?
Choose brackets rated for the motor’s horsepower, typically in the 7.5–20 HP range in this guide. Exceeding the rating can stress the bracket and impact mounting stability.
Is adjustable height important?
Yes. Five-position or multi-position adjustments help optimize trim and balance as you vary loads, gear, or motor weight. This reduces drag and improves handling in rough water.
What about installation and durability?
Look for reinforced welded frames, stainless fasteners, and robust bases. Ensure mounting dimensions match your transom and that the base provides a stable platform to minimize motor sway during operation.
How should I maintain these brackets?
Rinse with fresh water after exposure to salt, dry completely, and inspect springs and latches for wear. Tighten mounting hardware as needed and replace corroded parts promptly to preserve performance.
FAQ
- Q: Can these brackets support 4-stroke motors? A: Some brackets are rated for up to 15 HP or 20 HP and can handle certain 4-stroke engines; check the HP rating and weight limit for each model.
- Q: Are these brackets easy to install by myself? A: Most brackets are designed for straightforward mounting, but verify mounting hole patterns and ensure proper alignment with the transom.
- Q: Do all brackets use stainless steel springs? A: Not all; some use torsion springs or different counter-balance mechanisms depending on model.
- Q: Which bracket is best for saltwater use? A: Stainless steel or aluminum with corrosion-resistant finishes are preferable for saltwater environments.
- Q: Is a retractable bracket better for trailering? A: Retractable designs can improve stability and reduce exposure to damage when not in use, but require regular maintenance of the retract mechanism.
