1. Garelick 71055 Outboard Motor Bracket: Best Overall
The Garelick 71055 is a well-engineered transom extension that earned top marks in our evaluation for its durable aluminum build and straightforward installation. Owner feedback consistently praises its corrosion resistance and secure fit. We found the adjustable mounting plate a standout feature, allowing precise motor positioning without shims.
However, this bracket is limited to motors under 115 lbs, so it won’t work for larger outboards. If you have a heavy engine, you should skip this pick and consider a higher-capacity model. For small to mid-size outboards, it’s a reliable choice.
- Heavy-duty welded aluminum construction with stainless steel hardware
- Adjustable mounting plate for perfect motor alignment
- Includes all necessary mounting bolts and instructions
Pros: Rust-resistant and built to last; Easy to adjust and install
Cons: Not suitable for motors over 115 lbs
2. SE Sport 200 Outboard Motor Bracket: Runner Up
The SE Sport 200 is a strong contender with a 200 lb capacity that suits most small to medium outboards. In our research, we found the welded aluminum frame and powder coating provide excellent durability. The spring-assisted tilt is a nice convenience, though some owners note it requires a bit of force to engage.
Where this bracket falls short is the mounting plate thickness: it may not fit thicker transoms without modification. If your transom is over 4 inches, you’ll need to check compatibility. Otherwise, it’s a solid, budget-friendly option.
- All-welded marine-grade aluminum with powder coat finish
- Spring-assisted tilt for easy motor lifting
- Pre-drilled mounting holes for quick installation
Pros: High weight capacity; Good value for the price
Cons: Spring can be stiff for some users
3. BoatBuckle 500 lb Transom Saver: Heavy Duty Pick
The BoatBuckle 500 lb is built for large outboards and heavy-duty use. Our evaluation of the specs shows it can handle motors up to 500 lbs, making it one of the strongest options. The adjustable width and rubber padding add versatility and protection. Owner feedback highlights its rock-solid stability on the water.
The main drawbacks are its weight and cost. Installation requires two people due to its bulk, and it’s overkill for smaller engines. Skip this if you have a light outboard; it’s best for large, powerful motors.
- Heavy-gauge steel construction with zinc plating
- Adjustable width from 24 to 36 inches
- Includes rubber padding to protect transom
Pros: Extremely durable and high capacity; Protects transom from damage
Cons: Heavy and bulky to install; Higher price point
4. Attwood 14390-4 Outboard Motor Bracket: Best for Small Motors
The Attwood 14390-4 is a lightweight bracket designed for small trolling motors or lightweight outboards. In our comparison, it stands out for its low price and simplicity. Owner feedback indicates it works well for its intended use, but the aluminum construction is less robust than steel.
We advise skipping this if you have a motor over 50 lbs or plan to use it in rough waters. It’s best for calm lakes and small dinghies where weight savings matter.
- Lightweight aluminum construction
- Compact design for easy storage
- Includes mounting hardware
Pros: Very affordable; Easy to install and remove
Cons: Low weight limit; Not as durable as steel options
5. T-H Marine 4-Stroke Outboard Bracket: Premium Pick
The T-H Marine 4-Stroke bracket is a premium option with exceptional craftsmanship. Our research shows it uses high-grade materials and precise manufacturing. Owners rave about the smooth tilt and secure hold. It’s designed specifically for 4-stroke outboards, which often have different mounting needs.
The biggest downside is the cost, which may be prohibitive for budget-conscious buyers. Also, it’s sometimes out of stock. If you want the best and have the budget, this is a top choice. Otherwise, consider the Garelick.
- Marine-grade 5052 aluminum with stainless steel fasteners
- Integrated lifting handle for easy tilt
- Precision laser-cut for perfect fit
Pros: Excellent build quality; Smooth tilting mechanism
Cons: Expensive; Limited availability
6. C.E. Smith 200 lb Outboard Bracket: Best Value
The C.E. Smith 200 lb bracket offers excellent value for those needing a mid-capacity option. In our evaluation, the steel frame provides strength, but the powder coating can chip over time, leading to rust. Owner feedback notes that regular painting is needed. It’s a solid choice if you’re on a tight budget.
However, we recommend skipping this if you boat in saltwater, as corrosion will be a problem. For freshwater use, it performs adequately. The weight is also a consideration for portability.
- Steel construction with black powder coat
- Adjustable mounting plate
- Includes hardware and instructions
Pros: Great price for the capacity; Sturdy steel build
Cons: Prone to rust if not maintained; Heavier than aluminum brackets
7. Bass Pro Shops XPS Transom Bracket: Compact Design
The Bass Pro Shops XPS bracket is designed for portability. Its foldable design and quick-release pin make it easy to remove and store. In our research, it’s best for small trolling motors or as a temporary mount. Owner feedback indicates it works well for light use but flexes under heavier loads.
We suggest skipping this if you need a permanent, heavy-duty solution. It’s ideal for kayaks or small boats where space is limited. The lower weight limit and flexibility are its main weaknesses.
- Aluminum alloy with black anodized finish
- Foldable design for compact storage
- Quick-release pin for easy removal
Pros: Lightweight and portable; Easy to store
Cons: Low weight capacity; Not as sturdy as fixed brackets
Frequently Asked Questions
What is a transom extension and why do I need one?
A transom extension is a bracket that mounts to the back of your boat to raise or extend the outboard motor’s mounting point. It’s used to lift the motor for shallow water operation, to mount an auxiliary engine, or to correct a low transom. It helps prevent the motor from hitting bottom and improves performance.
How do I know what weight capacity I need?
Check your outboard motor’s weight from the manufacturer’s specs. Choose a bracket with a capacity that exceeds your motor’s weight by at least 20% for a safety margin. For example, a 100 lb motor needs a bracket rated for at least 120 lbs. Overloading can cause failure or damage.
Can I install a transom extension myself?
Yes, most brackets come with hardware and instructions. You’ll need basic tools like a drill, wrench, and sealant. Ensure the transom is thick enough to support the bracket. If you’re not comfortable, a professional installation is recommended for safety.
Will a transom extension affect my boat's handling?
It can slightly change the boat’s balance and steering. Raising the motor may reduce stern lift and increase bow rise. Test in calm water first. Proper adjustment of the motor angle is crucial. Most brackets allow for tilt adjustment to compensate.
What materials are best for saltwater use?
Marine-grade aluminum (e.g., 5052) or stainless steel are best for saltwater. Avoid plain steel or zinc-plated brackets as they corrode quickly. Look for powder-coated or anodized finishes. Rinse the bracket after each use to prolong life.
Our Verdict
After comparing specs and owner feedback, the Garelick 71055 is our top pick for most boaters due to its balance of durability, ease of installation, and safety. For those needing higher capacity, the SE Sport 200 is a strong runner-up with excellent value. Choose based on your motor weight and transom thickness.
