TSP-1 & TSP-2DP Transom Support Plate Kit
This cast aluminum transom plate kit is designed to reinforce transom top and lower bolt holes. Best for boaters needing reliable support at critical mounting points during twin-engine setups. The kit includes two plates sized for flexibility in mounting arrangements, making it suitable for boats with varied transom configurations. The 3/8″ thickness offers robust stiffness without excessive weight. Use this when the transom needs direct reinforcement to prevent flex under engine torque.
Who it’s best for: Boat owners seeking reinforced mounting points for twin outboards on a solid transom. Choose this if you want dedicated top and bottom bolt hole reinforcement and a two-pack for additional mounting options.
Limitations: This kit does not provide a full engine bracket by itself; it reinforces the transom and should be paired with compatible brackets or mounting hardware.
1 Pair Outboard Motor Brackets
These wall-mount motor brackets offer a space-saving storage solution for twin engines in a workshop, garage, or dockside area. They’re designed for easy installation with screw holes and provide sturdy support for hanging and organizing engines when not in use. Best for boaters who need a dedicated storage solution to keep engines off the deck or away from moisture during non-use periods.
Who it’s best for: Dockside or workshop users needing a compact, durable way to store twin outboards securely. This option is better for temporary or seasonal storage rather than live mounting on a boat during operation.
Limitations: Not a mounting bracket for active use on the transom; intended for storage only. Check weight limits to ensure compatibility with your engine models.
Universal Tie Bar For Twin Outboard Engines
This tie bar is designed to help position and align two twin outboard engines within a defined spacing range (670–900 mm). It supports balanced torque distribution, reducing crowning or misalignment when engines are mounted side by side on a transom. Best for boats requiring precise engine spacing to maintain trim and steering response.
Who it’s best for: Owners needing adjustable alignment between two engines to ensure even load distribution and predictable steering. Choose this if your twin setup requires exact spacing for performance and balance.
Limitations: The bar length is adjustable but must match your engine models and transom dimensions; verify compatibility before purchase.
Transom Reinforcement Plate (Aluminum)
Designed as an engine support bracket reinforcement, this 0.2″ thick aluminum plate adds rigidity to the transom area across most outboard motors. It’s a practical option when you need extra stiffness to prevent flex under engine torque, especially on smaller boats or installations with limited transom support hardware.
Who it’s best for: Boaters seeking a lightweight reinforcement plate to improve transom rigidity. Choose this when you want a straightforward addition to support brackets without heavier structural steel.
Limitations: This plate is a reinforcement accessory, not a complete mounting bracket. Ensure you have compatible mounting hardware to integrate it into your twin-engine setup.
Boat Outboard Motor Bracket (20 HP)
This aluminum boat engine bracket is designed for mid-range power mounting, suitable for up to 20 HP engines. It provides a sturdy, weather-resistant mounting point that can help maintain engine position and stability in light to moderate twin-engine applications. Best for boats requiring a reliable, simple mounting option for one engine or limited twin configurations.
Who it’s best for: Users with lighter twin-engine setups or single-engine boats needing a compatible second bracket for balance. Choose this when you prioritize corrosion resistance and straightforward installation.
Limitations: May not support higher horsepower engines or heavy-duty twin arrangements; verify engine weight and mounting hardware compatibility with your transom.
Buying Guide: Twin Outboard Bracket Essentials
What to consider before buying twin outboard brackets
- Engine weight and horsepower: Match brackets and plates to the total weight and power of your engines to avoid overloading the transom.
- Transom material and reinforcement: Reinforcement plates help if you have aging or soft transoms. Pair with appropriate bracketing for strength.
- Mounting surface: Decide between transom, top-mourning, or wall-mounted storage depending on whether you need operation support or storage solutions.
- Material and corrosion resistance: Aluminum and cast aluminum offer good strength-to-weight ratios with corrosion resistance for saltwater use.
- Adjustability: Tie bars and adjustable brackets improve alignment, spacing, and balance, which affect trim and steering.
- Installation complexity: Some items are standalone brackets; others require reinforcement plates or multiple components for a complete setup.
FAQ
- What is a transom reinforcement plate used for?
It strengthens the transom mounting area to prevent flexing when engines exert torque, improving mounting stability.
- Can I install twin outboard brackets on any boat?
Not always. Check transom thickness, height, and mounting hole patterns to ensure compatibility with your boat’s structure.
- Do I need a tie bar for twin engines?
A tie bar helps maintain precise spacing and alignment between engines, which supports balanced thrust and steering response.
- Is aluminum rust-proof for saltwater use?
Aluminum offers corrosion resistance, but proper coatings and maintenance are still essential in saltwater environments.
- Should I purchase storage brackets or mounting brackets?
Storage brackets keep engines off decks and dry; mounting brackets are for active use on the transom. Choose based on your needs.
