Product Details

This Wedge Transom Saver Motor Toter is a protective support device for trailering outboard motors with 2 or 3-ram hydraulic trim/tilt systems. It provides a stable cushion between the engine and the transom by attaching to the trim/tilt piston, preventing damage from road shock and vibration. It fits a wide range of Yamaha, Mercury, Honda, Johnson/Evinrude, and Suzuki outboards from 90 to 350 HP.

This part is a direct replacement for Yamaha MAR-MTSPT-YM-08 and the M-Y Wedge Universal Motor Support, offering a reliable aftermarket alternative.

  • Installs easily by sliding over the extended trim/tilt piston rod.
  • Made from durable EPDM rubber and high-tech plastic, resistant to UV rays and saltwater.
  • Includes a set of steering stop locks (centering clips) to prevent engine sway.

Installation Notes

  1. Trim your outboard motor up to its maximum tilt position to fully extend the hydraulic rams.
  2. Identify the correct trim/tilt piston for installation. On most models, this is the main or starboard-side ram. Yamaha V8 models may require two wedges.
  3. Clean the piston rod of any grease or debris to ensure a secure fit.
  4. Slide the Wedge Transom Saver over the exposed piston rod. The self-centering design will help align it.
  5. Slowly lower the motor until the Wedge rests securely between the motor and the transom mount, providing gentle pressure. Do not apply excessive force.
  6. Install the included centering clips (steering stabilizers) on the hydraulic steering rods to prevent the motor from turning during transit.

Troubleshooting & FAQ

Which outboard motors is this transom saver compatible with?

This wedge-style transom saver is designed for a broad range of Yamaha, Mercury, Honda, Johnson/Evinrude, and Suzuki outboards from 90-350 HP that use a 2 or 3-ram hydraulic trim/tilt system. Please see the compatibility table for specific model ranges.

How do I install the Wedge Transom Saver?

Installation is simple: tilt your motor up, slide the wedge over the main trim piston rod, and then lower the motor until it rests snugly on the wedge. Use the included clips to stabilize the steering.

Does this work on single-ram tilt systems?

No, this product is specifically engineered for outboards equipped with either 2-ram or 3-ram trim/tilt systems. It will not function correctly or safely on single-ram setups.

What are the included centering clips for?

The included clips are steering stabilizers. They attach to your boat's hydraulic steering rods to prevent the outboard from turning and swaying from side to side while trailering, providing an extra layer of security.

Do I need one or two units?

Most applications only require one transom saver. However, some large engines like the Yamaha V-8 models (F300-F350) require two units—one for the port ram and one for the starboard ram—for balanced support.

What is the transom saver made of?

It is constructed from a combination of durable, high-tech plastic and EPDM rubber. This composition is designed to absorb shock and resist damage from UV light and saltwater exposure.
