Transom Saver – Fits Single Ram Outboard Motors
This transom saver support is engineered to protect your boat's transom and the outboard motor's trim/tilt system during trailering. The wedge-style support installs directly onto the single hydraulic ram, absorbing road shock and preventing unwanted engine movement, which can cause damage to the steering and hydraulic systems.
Designed for a wide range of outboard motors, including Mercury, Yamaha, Honda, Suzuki, Tohatsu, Evinrude, and Johnson models with single-ram trim/tilt. This unit is an aftermarket replacement for JLM Marine Transom Saver Support and M-Y Wedge Transom Saver M-YU123.
-
Installation Method: Installs in seconds with no drilling required; slides directly onto the tilt ram.
-
Material: Made from high-density, UV-resistant EPDM rubber to withstand extreme temperatures.
-

Installation Guide
- Trim the outboard motor to its highest tilt position.
- Identify the main hydraulic trim/tilt ram shaft.
- Slide the transom saver wedge firmly onto the exposed ram shaft. The notches inside are designed to help grip the shaft.
- Slowly lower the motor until the wedge is held securely between the motor's mounting bracket and the transom assembly.
- Confirm the motor is stable and pressure is applied to the wedge before trailering.
Troubleshooting & FAQ
Q: How do I know if this transom saver fits my specific Mercury model?
A: This transom saver fits most single-ram Mercury models from 40-175 HP. For Verado V6/V8 and certain Racing models (300R-500R), two units are required. Always check the compatibility table and verify your engine has a single main tilt shaft.
Q: Can I use this on a dual-ram system?
A: No, this wedge is designed specifically for single-ram trim/tilt systems. Using it on a dual-ram system will not provide proper support and risks damaging your equipment.
Q: What is the benefit of using a rubber wedge over a traditional transom saver bar?
A: This EPDM rubber wedge installs directly on the hydraulic ram, preventing motor "shimmy" and stress on the tilt system without needing a connection to the trailer frame. It's a quick, drill-free installation that effectively dampens vibrations.
