Transom Saver Wedge Support – 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, preventing costly damage and wear.

This part is a direct replacement for GHmarine 1H03, Yamaha MAR-MTSPT-YM-08, and M-Y Wedge Universal Motor Support, offering a reliable fit for a wide range of outboard models including Yamaha (115–350 HP), Mercury (135–300 HP), Honda (90–300 HP), Johnson/Evinrude (150–300 HP), and Suzuki (140-350 HP).

  • Installation Method: Simply slides over the trim/tilt piston rod for a secure fit.
  • Durable Construction: Made from high-quality EPDM rubber and reinforced plastic to resist UV and saltwater damage.
  • Complete Kit: Includes two outboard steering stabilizer clips to prevent engine turning during trailering.

Package Contents

  • 1 x Wedge Transom Saver Support (GHmarine 1H03)
  • 2 x Outboard Steer Stop Stabilizer Clips

Installation Guide

  1. Raise the Outboard: Tilt your outboard motor to the full "up" position using the power trim/tilt switch.
  2. Position the Wedge: Slide the Transom Saver Wedge over the exposed piston rod on one of your main trim rams. For most engines, the starboard (right) side ram is used.
  3. Lower the Outboard: Carefully lower the engine until it makes firm contact with the wedge, creating pressure that holds it in place. Do not apply excessive pressure.
  4. Attach Stabilizer Clips: Clip the included steering stabilizers onto the hydraulic steering cylinder rods on both sides of the motor. This prevents the engine from turning left or right during transit.
  5. Final Check: Before trailering, ensure the engine is securely resting on the wedge and the steering is locked straight.

Troubleshooting & FAQ

Q: How do I confirm this fits my engine?
A: This wedge fits most Yamaha, Mercury, Honda, Johnson/Evinrude, and Suzuki outboards within the specified HP ranges and equipped with a 2 or 3-ram power trim/tilt system. Please check the compatibility tables above. Note that Johnson/Evinrude Generation 2 models are not compatible, and V-8 Yamaha models require two wedges.

Q: What are the 'stabilizer clips' for?
A: The two included clips attach to your hydraulic steering rods. Their purpose is to lock the steering and prevent the engine from turning side-to-side while you are trailering, providing an extra layer of security.

Q: Why should I use a transom saver?
A: During trailering, road bumps and vibrations can put significant stress on your boat's transom, the motor mounts, and the outboard's hydraulic trim system. This wedge stabilizes the motor's weight, absorbing shock and preventing wear or damage to these critical components.
