Installation Notes

  1. Tilt your outboard motor to the highest position.
  2. With the motor raised, slip the transom saver support over the exposed trim ram piston(s). Ensure it is seated securely.
  3. For engines with a single trim ram, place the support on the designated ram (typically starboard/right side for certain models).
  4. Slowly lower the motor until the support is held firmly between the motor and the tilt/trim unit, preventing further downward movement. Do not apply excessive pressure.
  5. Install the included steer stop clips onto the hydraulic steering cylinder rods to prevent engine sway during transit.

Troubleshooting & FAQ

What is this transom saver used for?

It is designed to absorb stress and prevent damage to your boat’s transom and the outboard's hydraulic trim/tilt system during trailering. It stabilizes the engine and reduces bouncing caused by road bumps.

How do I know if this will fit my engine?

This support fits most outboards with 2 or 3 ram trim systems from major brands. Check the detailed compatibility table on this page. It is not compatible with Mercury Verado or Racing models.

Is any modification required for installation?

For most engines, no modification is needed. However, certain Yamaha and Honda models may require minor trimming of the support base or boring of the entry hole for a perfect fit. Please see the notes in the compatibility table.

What are the included steer stop clips for?

The steer stop clips are placed on your hydraulic steering cylinder rods. They prevent the engine from turning and swaying from side to side during trailering, providing an extra layer of stability and protecting the steering system.

How do I maintain the transom saver?

Maintenance is minimal. Regularly inspect the rubber for any signs of cracking, wear, or degradation. Clean with fresh water after use in saltwater environments. Replace it if you see any significant damage to ensure it provides adequate support.
