Marinebaby Boat Outboard Motor Bracket
Brand: Marinebaby. This heavy-duty aluminum bracket is designed for 2-stroke motors from 7-1/2 HP to 20 HP. It features stainless steel springs to counterbalance motor weight and a solid polypropylene mounting board for lasting rigidity. With a 5-position height adjustment range from 195 mm to 320 mm, it’s well suited to boats that experience variable loading or water conditions. Best for boat owners seeking a durable, easy-to-adjust solution for mid-range power motors. A potential limitation is the weight of the aluminum construction, which may affect mounting considerations on very light vessels.
Panther 55-0410 Auxiliary Outboard Bracket
Brand: Marinetech. This auxiliary bracket supports five vertical positions for trolling or auxiliary runs. The anodized aluminum bracket is built to handle the torque outputs of modern four-stroke engines, with a 2”-thick mounting board and heavy-duty stainless hardware. Hand-adjustable via a simple knob, this option is ideal for boaters who frequently adjust motor height to match water and load conditions. Caution: ensure you have sufficient space and mounting area for the taller profile when retracted.
Outboard Motor Bracket Auxiliary Stainless Steel 20HP
Brand: Mojiate. This bracket uses marine-grade stainless steel with a heavy-duty welded frame and stamped components. It supports 2-stroke motors from 7.5 HP to 20 HP with a 8” × 8-5/8” mounting footprint and 8-1/4” × 10-3/8” broad size. The mounting base is plastic, reducing metal-on-boat wear. Best for boats needing a corrosion-resistant option with robust construction, though the base material may affect long-term wear on abrasive decks.
FUTURUP Boat Outboard Bracket
Brand: FUTURUP. This aluminum bracket uses a plastic base and offers a 7-1/2 to 20 HP range with a broad size of 8-1/4” × 10-3/8” and mounting size of 5-1/4” × 9”. It features a retractable design for easier steering and stability with long- or short-shaft motors. A notable strength is the wide track body and reinforced welds; however, some users may prefer a fully stainless setup for saltwater longevity.
2 Stroke Outboard Bracket Kicker for Boat Up to 20HP
Brand: Haida. This 2-stroke-focused bracket uses 304 stainless steel, with a 4-position manual lift system. It has a compact mounting footprint and a plastic base that reduces deck wear. Best for users with 2-stroke engines who want a simple, cost-effective mounting solution. The manual lift may require more effort during frequent height changes, especially in rough water.
Buying Guide
What matters most when choosing a large outboard motor bracket?
- HP compatibility: Match the bracket’s rated horsepower with your engine (7.5–20 HP is common in these options).
- Material and corrosion resistance: Aluminum is lightweight and sturdy; stainless steel offers superior saltwater durability but can be heavier and pricier.
- Adjustability: Five-position height adjustments help tailor motor trim to water conditions and load.
- Mounting footprint: Ensure mounting dimensions align with your transom or mounting board; verify width and depth to avoid interference with other gear.
- Base and mounting hardware: A solid base (plastic vs. PP) affects vibration dampening and wear; stainless hardware resists corrosion.
- Weight and balance: The bracket should support lifting and balancing the engine without undue strain on the boat structure.
- Maintenance: Consider ease of inspection, cleaning, and replacement parts for the bracket’s springs and hardware.
What to choose if you have a 4-stroke vs 2-stroke?
For 4-stroke motors, look for brackets with robust torsion springs and heavier-duty construction, like the Panther 55-0410 or FUTURUP, which handle higher torque and sustained stability. For 2-stroke motors, most aluminum or stainless brackets in this group perform well, with the Mojiate or Haida options offering good balance between cost and durability.
What’s a safe height range worth?
A five-position height range is a practical standard, enabling you to raise or lower the motor for different water conditions, loads, or when trailering. Choose a bracket with clear, repeatable locking positions to prevent drift during operation.
Are stainless options worth the extra cost?
Stainless brackets offer better saltwater longevity and reduced corrosion risk, making them a better long-term choice for brackish or marine environments. If you boat in fresh water or on a budget, aluminum-based brackets may be sufficient.
FAQ
- Q: Can these brackets fit any 20 HP outboard motor?
A: Most are designed for 7.5–20 HP engines; always check mounting size and weight limits before installation. - Q: Do these brackets require professional installation?
A: Simple brackets may be installed by able DIYers, but verify mounting strength and ensure proper sealing to prevent water intrusion. - Q: Which bracket is best for trolling?
- A: The Panther 55-0410 and FUTURUP options are particularly suited for trolling due to stable height adjustment and load handling.
- Q: How important is the mounting board material?
- A: A durable mounting board reduces fatigue and distributes weight; plastic bases can dampen vibration and protect the transom.
- Q: Should I choose a manual or spring-loaded bracket?
- A: Spring-loaded brackets provide easier adjustments and balance, while manual brackets may suit simple setups with occasional position changes.
