Wedge Transom Saver Motor Toter – Fits Yamaha, Mercury, Honda, Johnson/Evinrude & Suzuki Outboards
This wedge-style transom saver provides essential support for outboard engines equipped with 2 or 3-ram power trim/tilt systems. By stabilizing the engine and steering mechanism during trailering, it effectively reduces stress on the transom assembly, motor mounts, and hydraulic system. It is designed to protect your investment by absorbing road shock and preventing unwanted engine movement.
This unit is a direct replacement for Yamaha part number MAR-MTSPT-YM-08 and the M-Y Wedge Universal Motor Support. It is compatible with a wide range of outboard models from major brands, ensuring broad application.

Installation Guide
- Trim your outboard motor up to its highest position.
- Clean the exposed trim/tilt piston rod to ensure it is free of debris.
- Slide the Wedge Transom Saver over the designated piston rod. For most models, this is the starboard (right-side) rod, but confirm your specific setup.
- Slowly lower the motor until it makes firm contact with the transom saver wedge. Do not apply excessive pressure.
- Center the engine and attach the included steering stop locks (centering clips) to the hydraulic steering rods to prevent the engine from turning during transit.
- Before launching your boat, be sure to trim the motor up and remove the transom saver and centering clips.
Troubleshooting & FAQ
Q: How do I know if this will fit my specific outboard model?
A: This transom saver is designed for a wide range of Yamaha, Mercury, Honda, Johnson/Evinrude, and Suzuki outboards with 2 or 3-ram trim/tilt systems. Please consult the "Compatible Engine Models" table and confirm your engine's HP and brand. The most important check is ensuring your motor has an exposed trim/tilt rod for the wedge to slide onto.
Q: My Yamaha V8 engine has two trim rods. Do I need two of these?
A: Yes, for Yamaha V-8 models (F300-F350), you must use two transom savers—one for the port and one for the starboard trim rod—for proper support.
Q: What are the included clips for?
A: The included clips are steering stabilizers, also known as centering clips. They attach to your boat's hydraulic steering rods to lock the engine in a straight position and prevent it from turning and shifting while trailering.
