Large outboard motors can exert tremendous stress on a boat’s transom during trailering. A transom saver (or outboard support) absorbs road shocks and distributes the motor’s weight to the trailer frame, preventing cracks and structural damage. We researched manufacturer specs, safety standards, and aggregated owner feedback to compare seven top models. Our evaluation focuses on load capacity, adjustability, corrosion resistance, and ease of use for motors typically over 150 hp. Here are our findings.

1. Attwood 14321-6 Transom Saver: Best Overall
The Attwood 14321-6 is a well-established transom saver that we found consistently recommended by owners of large outboards. Its aluminum construction provides a good strength-to-weight ratio, and the pivoting rubber pads help avoid scratches. The tool-free adjustment makes setup straightforward. In owner feedback, it reliably supports motors up to 250 hp without sagging.
However, the rubber pads are not replaceable and may show wear after several seasons, especially if used on long, rough hauls. If you trailer frequently over poor roads, consider a model with replaceable urethane pads. Otherwise, this is a solid, proven choice for most large outboards.
- Heavy-duty aluminum alloy resists corrosion and flex
- Pivoting rubber pads prevent marring the motor and transom
- Tool-free length adjustment with locking pin
Pros: Excellent build quality for the price; Quick to install and remove
Cons: Rubber pads can wear over time on rough roads
2. CE Smith CS-1500 Transom Saver: Runner Up
The CE Smith CS-1500 is a heavy-duty steel transom saver that we evaluated as ideal for the largest outboards, up to 350 hp. Its 600 lb rating and wide adjustment range ensure a secure fit. Owners report it stays rigid even on bumpy roads, and the rubber boots protect the motor and transom effectively.
Its main drawback is weight: at over 5 lbs, it adds noticeable heft. Also, the powder coating can chip if the support is dropped on concrete, exposing steel to potential rust. If you need maximum strength for a very large motor and don’t mind a bit of extra weight, this is a top contender.
- Steel tube construction with corrosion-resistant powder coating
- Wide range of adjustment fits most transom heights
- Includes non-marring rubber boots on both ends
Pros: Very sturdy under heavy loads; Long adjustment range
Cons: Heavier than aluminum models; Powder coat can chip if not careful
3. T-H Marine Transom Saver: Best Value
T-H Marine offers a budget-friendly transom saver that still delivers reliable support for many large outboards. Its anodized aluminum resists corrosion, and the rubber pads prevent damage. We found it works well for motors up to 200 hp. Owner feedback highlights its simplicity and ease of storage.
However, its 450 lb capacity is lower than others, so it’s not suitable for the heaviest engines (over 225 hp). The adjustment range is also shorter, which may not fit very tall transoms. For those with moderately large outboards on a budget, this is a smart pick.
- Lightweight aluminum with anodized finish
- Quick-release pin for easy length changes
- Soft rubber pads protect surfaces
Pros: Affordable without sacrificing essential features; Lightweight and easy to handle
Cons: Lower weight capacity than competitors; Not ideal for motors over 225 hp
4. Land'n'Sea Transom Saver: Premium Pick
The Land’n’Sea transom saver is built for saltwater environments where corrosion is a major concern. Its stainless steel shaft and machined aluminum ends are premium materials, and the urethane pads outlast rubber. We found it supports large motors securely, and the dual locking pins provide confidence.
That premium comes at a cost: it is significantly more expensive than other options. Also, its weight is comparable to steel models. If you trailer in saltwater areas and want a support that will last many years without rust, this is a worthy investment. For freshwater-only users, the extra cost may not be justified.
- Stainless steel construction for maximum rust resistance
- Machined aluminum end fittings with urethane pads
- Dual locking pins for added security
Pros: Exceptional corrosion resistance; Urethane pads are more durable than rubber
Cons: Higher price point; Heavier than aluminum models
5. Boat Buckle Transom Saver: Easiest Install
Boat Buckle uses a strap system that is incredibly simple: just hook it on the trailer and motor, then tighten. We found it takes seconds to install. The lack of metal ends means no scratches, and it stores flat. Owners of smaller large outboards (up to 175 hp) appreciate its convenience.
However, its 400 lb capacity is the lowest here, so it’s not for heavy motors. The nylon strap can also stretch with age, potentially reducing support. For light large outboards and those who prioritize ease over maximum strength, this is a good choice.
- Unique strap-based design eliminates metal contact
- Quick-adjust buckle for instant length changes
- Lightweight and folds for compact storage
Pros: Very easy to install and adjust; No risk of scratching painted surfaces
Cons: Lower weight capacity limits motor size; Nylon strap may stretch over time
6. Sto-A-Way Transom Saver: Compact Design
Sto-A-Way’s transom saver is designed for boaters with limited storage space. It telescopes down to a short length, making it easy to stow in a small compartment. The anodized aluminum is corrosion-resistant, and the rubber caps protect surfaces. We found it works for motors up to 150 hp.
Its 350 lb capacity is the lowest, so it’s not suitable for most large outboards over 200 hp. The telescoping mechanism can also get gritty and difficult to adjust if not cleaned regularly. If you have a moderately sized motor and need a very compact support, this is an option, but many large outboard owners will want something stronger.
- Telescoping design collapses to 24 inches for storage
- Anodized aluminum resists corrosion
- Includes rubber end caps
Pros: Very compact when collapsed; Lightweight
Cons: Low weight capacity for large outboards; Telescoping sections can bind if not kept clean
7. Myacht Transom Saver (Adjustable): Budget Pick
The Myacht transom saver is the most affordable option we evaluated. It provides basic support for large outboards, with a steel tube and rubber caps. For occasional trailering of motors up to 175 hp, it can get the job done. Owner feedback indicates it works but lacks refinement.
Its main issues are durability: the paint can chip and rust quickly, especially in saltwater areas. The steel is also less rigid than some competitors, leading to slight flex under heavy loads. We recommend this only for budget-conscious owners with lighter large outboards who trailer infrequently. For regular or heavy use, invest in a better-built model.
- Steel construction with basic paint finish
- Rubber end caps included
- Simple pin adjustment
Pros: Very low price point; Basic functionality for occasional use
Cons: Paint finish prone to rust; Not as sturdy as pricier models
Frequently Asked Questions
What is a transom saver and why do I need one for a large outboard?
A transom saver is a support bar that connects the outboard motor to the trailer frame during transport. It transfers the motor’s weight and absorbs road shocks, preventing stress cracks in the transom. For large outboards (over 150 hp), the extra weight makes a transom saver essential to avoid structural damage.
How do I choose the right transom saver for my large outboard?
Key factors include weight capacity (match or exceed your motor’s weight), adjustment range (must reach from trailer bracket to motor skeg), material (aluminum for light weight, steel for strength, stainless for saltwater), and pad quality (rubber or urethane). Also consider ease of installation and storage.
Can I use a transom saver with a jack plate?
Yes, but you need an adjustable transom saver that can extend to the correct length. Some models have a wide enough range to accommodate jack plates. Measure the distance from your trailer bracket to the motor skeg with the motor trimmed down to find the required length.
Should I trim my outboard up or down when using a transom saver?
Most transom savers are designed to be used with the motor trimmed fully down (vertical position). This puts the least stress on the transom. Some models allow a slight tilt, but always follow the manufacturer’s instructions. Never trailer with the motor tilted up without a support.
How do I maintain my transom saver?
Rinse with fresh water after saltwater use to prevent corrosion. Check rubber pads for wear and replace if cracked. Lubricate locking pins or threads periodically. Store in a dry place. Inspect before each trip for bends or damage.
Our Verdict
After researching specs and owner feedback, our top pick is the Attwood 14321-6 for its balance of strength, weight, and value. For heavier motors or those wanting extra durability, the CE Smith CS-1500 is an excellent runner up. Choose based on your motor’s weight and trailering conditions.
