Product Details
This Transom Saver Support with Steering Cylinder Locks provides a safe and effective way to protect your outboard motor's transom, steering, and trim/tilt system while trailering.

- Features a simple, self-centering slide-on installation on the trim/tilt piston rod.
- Made from high-grade rubber and plastic to absorb road shock and protect hydraulic components.

- To remove, simply trim the outboard motor back to the "up" position and remove the wedge and steering locks.
Troubleshooting & FAQ
How do I know if this will fit my specific motor?
This transom saver fits most major outboard brands (Yamaha, Mercury, Honda, Johnson/Evinrude, Suzuki) with 2-ram and 3-ram power trim/tilt systems in the 90-350HP range. Please check the compatibility table for specific model series and any special notes, such as installation side.
On which side of the engine do I install the wedge?
Installation varies by brand. Install it on the port (left) side for Yamaha and Suzuki outboards. For Mercury, Honda, and Johnson/Evinrude outboards, install it on the starboard (right) side.
Why are the two steering cylinder locks necessary?
The included steering locks snap onto the hydraulic steering cylinder rods to keep the engine centered during trailering. This prevents the outboard from turning, which can cause damage to the steering system and boat components over time due to road vibrations.
Do I need to buy one or two transom savers?
For the vast majority of motors, only one transom saver is required. The only common exception is the Yamaha V-8 F300-F350 series, which requires two wedges (one for each trim ram) for proper support.
What happens if I don't use a transom saver?
Trailering an outboard without proper support can put significant stress on the boat's transom, leading to cracks and costly structural damage. It also causes wear and tear on the motor's hydraulic trim and tilt system.
