Product Details

This wedge-style Transom Saver – Fits Single Ram Outboard Motors (Mercury, Yamaha, Honda, Suzuki, Tohatsu, Evinrude, Johnson) is engineered to protect your boat's transom and your outboard motor’s hydraulic system during trailering.

This part serves as a direct replacement for interchange numbers M-Y Wedge M-YU123 and the JLM Marine Transom Saver Support.

Installs in seconds without drilling by clipping directly onto the tilt shaft.
Made from high-density EPDM rubber to withstand compression and temperature extremes.
Includes one transom saver wedge with 10 inner notches for a secure grip on the ram.

1 x Transom Saver Wedge

Installation Notes

Tilt your outboard motor to its highest position to fully extend the trim/tilt ram.
Securely clip the transom saver wedge onto the exposed single hydraulic ram shaft.
Slowly lower the motor until it applies firm pressure to the wedge, creating a stable cushion.
Before trailering, always confirm the motor is snug against the wedge and cannot bounce or sway.

Troubleshooting & FAQ

How do I know if this wedge fits my outboard motor?

This transom saver is designed for outboard motors with a single main trim/tilt ram. Check our compatibility table for specific brands, models, and HP ranges. If your motor has twin rams (like some high-HP Mercury Verado models), you will need two units. Always visually inspect your motor's hydraulic system to confirm it has one central ram before ordering.

Is this better than a traditional transom saver bar?

A wedge-style saver offers a different approach. It stabilizes the engine by cushioning the hydraulics, absorbing road shock directly at the ram. Traditional bars transfer this force to the trailer frame. Wedges are faster to install, require no drilling, and take up less storage space. The best choice depends on your boat, trailer configuration, and personal preference.

My Mercury Verado requires two units. How do I install them?

For engines like the Mercury Verado V6/V8 and some Racing models that have two hydraulic trim rams, you must use two transom saver wedges. Place one wedge on each of the two rams before lowering the engine. This ensures the load is distributed evenly, providing stable support during transit.

How often should I inspect the transom saver?

Inspect the wedge before each use. Look for any signs of cracking, splitting, or deformation in the rubber. Exposure to UV rays, fuel, or oil can degrade the material over time. Replace it immediately if you notice any damage that could compromise its ability to support the engine.

What are the signs of a failing transom saver?

A failing wedge may show visible cracks or have a "squashed" appearance, indicating it has lost its compressive strength. During trailering, you might notice more engine bounce than usual. If the wedge no longer fits snugly on the ram or falls off easily, it's time for a replacement.

Can I trim my motor up or down with the wedge installed?

No. The wedge is designed to lock the engine in a partially tilted position for trailering only. Attempting to operate the trim/tilt system with the wedge installed can damage the hydraulic pump, the motor, or the wedge itself. Always remove it before launching your boat or operating the engine.
