Transom Saver – Fits Single Ram Outboard Motors (Mercury, Yamaha, Honda, Suzuki, Tohatsu, Evinrude, Johnson)
This wedge-style transom saver is engineered to stabilize your outboard motor during trailering, protecting your boat’s transom and the engine's hydraulic trim and tilt system. By absorbing road shock and preventing unwanted movement, it reduces stress on critical components.
Designed for a wide range of outboard motors with single-ram trim/tilt systems, this support is compatible with current models from Mercury, Yamaha, Honda, Suzuki, Tohatsu/Nissan, and Evinrude/Johnson. It serves as a direct replacement for parts like M-Y Wedge M-YU123 and the JLM Marine Transom Saver Support.
-
Installation Method: Installs in seconds without drilling; slides directly onto the hydraulic tilt ram.
-
Material: Constructed from high-density, durable EPDM rubber designed to withstand extreme temperatures.

Package Contents
Installation Guide
- Raise your outboard motor to its maximum tilt position.
- Identify the main hydraulic trim/tilt ram. This is typically the thickest, center-most piston.
- Slide the Transom Saver Wedge onto the exposed ram shaft. Ensure a snug fit.
- Slowly lower the motor until its weight rests securely on the wedge, compressing it slightly.
- Confirm the motor is stable and does not have excessive side-to-side play. The wedge should now absorb road shock during transit.
Troubleshooting & FAQ
Q: How do I know if this transom saver will fit my motor?
A: This wedge is designed for outboard motors with a single hydraulic trim/tilt ram. Check the compatibility tables on this page for specific brands, HP ratings, and models. If your motor has dual rams (common on larger engines like the Mercury Verado V6/V8), you may need two wedges.
Q: Do I need one or two wedges for my engine?
A: Most compatible motors require only one wedge. However, certain high-performance or heavy models, such as the Mercury Verado V6/V8 (250-400 HP) and Racing series (300R-500R), require using two wedges for proper support.
Q: How is this different from a traditional transom saver bar that connects to the trailer?
A: This wedge-style saver works by stabilizing the engine at the hydraulic ram, preventing harmful jarring and movement without being attached to the trailer. This design avoids potential frame stress and is faster to install and remove.
Q: OEM vs. Aftermarket?
A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
Q: How fast do you ship and how much does it cost?
A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.
Q: What is your warranty and return policy?
A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details. Returns are accepted within our standard return window (unused & in original condition); please see our policy page or reach out for instructions.
