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.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eIs this better than a traditional transom saver bar?\u003c\/summary\u003e\u003cp\u003eA 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.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eMy Mercury Verado requires two units. How do I install them?\u003c\/summary\u003e\u003cp\u003eFor 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.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eHow often should I inspect the transom saver?\u003c\/summary\u003e\u003cp\u003eInspect 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.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat are the signs of a failing transom saver?\u003c\/summary\u003e\u003cp\u003eA 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.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I trim my motor up or down with the wedge installed?\u003c\/summary\u003e\u003cp\u003eNo. The wedge is designed to lock the engine in a partially tilted position for trailering only.
