Product Details
This Wedge Transom Saver Motor Support is designed to support trailered outboard motors equipped with 2- or 3-ram hydraulic trim/tilt systems. It fits over an extended trim/tilt piston rod and provides a stable support point between the engine and transom area, helping reduce movement and the effects of road shock and vibration during transport.
The wedge-style design is intended for a broad range of Yamaha, Mercury, Honda, Johnson/Evinrude, and Suzuki outboards. Confirm your engine's trim/tilt configuration and installation position before ordering.
This aftermarket support is listed as a replacement reference for Yamaha MAR-MTSPT-YM-08. Reference numbers identify comparable applications and should be checked against the original component and your engine configuration.
- Slides over the extended trim/tilt piston rod for installation.
- Wedge-shaped, self-centering support design.
- Includes two steering stabilizers/centering clips to help limit engine steering movement while trailering.
- Constructed from durable plastic and EPDM rubber for marine and outdoor use.

Installation Notes
- Trim the outboard to its maximum tilt position so the hydraulic ram or rams are fully extended.
- Identify the correct trim/tilt piston for your engine. On many applications, the support is installed on the main or starboard-side ram.
- Clean the exposed piston rod and remove grease, dirt, or debris that could prevent a secure fit.
- Slide the wedge support over the exposed piston rod. Ensure that it is seated and aligned correctly.
- Slowly lower the motor until the support rests securely between the motor and transom mount. Do not force the motor against the support.
- Install the two included steering stabilizers/centering clips on the hydraulic steering rods as appropriate for your steering system.
- Confirm that the support and stabilizers remain secure before towing, and recheck them periodically during extended transport.
Troubleshooting and FAQ
Which outboard motors is this transom saver designed for?
It is designed for compatible Yamaha, Mercury, Honda, Johnson/Evinrude, and Suzuki outboards using 2- or 3-ram hydraulic trim/tilt systems. Review the application table and compare your engine's ram arrangement before ordering.
How is the wedge support installed?
Raise the motor, extend the appropriate trim/tilt ram, slide the wedge over the exposed piston rod, and lower the motor gently until it rests securely on the support. Install the two included steering stabilizers on the steering rods where appropriate.
Does this support work on a single-ram tilt system?
No. This support is intended for compatible 2- or 3-ram hydraulic trim/tilt arrangements and should not be used on a single-ram setup unless the application is specifically confirmed.
What are the included steering stabilizers for?
The two included stabilizers/centering clips help limit steering movement and side-to-side engine sway during trailering when installed correctly on the steering rods.
Do I need one or two supports?
Most compatible applications use one support. Certain large engines or configurations, including some Yamaha V8 applications, may require two supports—one for each ram. Check the engine manufacturer's guidance and the physical ram arrangement.
What is the support made of?
The support uses a combination of plastic and EPDM rubber intended for marine and outdoor trailering conditions.
Is this an OEM component?
No. This is an aftermarket replacement support. Yamaha MAR-MTSPT-YM-08 is provided as a reference number for application comparison and does not indicate that this product is manufactured by Yamaha.
How should I verify compatibility?
Compare the original support, piston-rod dimensions, ram arrangement, installation position, and engine model details. Do not rely on horsepower alone; year, model, stroke, and trim/tilt configuration can affect fit.
Safety and Important Information
- Verify the engine model, year, horsepower, stroke, ram arrangement, and physical dimensions before ordering.
- Do not use this support on a single-ram system unless compatibility has been specifically confirmed.
- Inspect the support and steering stabilizers for damage, looseness, or deterioration before each trip.
- Lower the motor gently onto the support; do not use excessive force or rely on the support as a substitute for proper trailering procedures.
- Professional installation is recommended when the correct installation position is unclear.
