Q: How do I know if this will fit my specific outboard model?
A: This transom saver is designed for a wide range of Yamaha, Mercury, Honda, Johnson/Evinrude, and Suzuki outboards with 2 or 3-ram trim/tilt systems. Please consult the "Compatible Engine Models" table and confirm your engine's HP and brand. The most important check is ensuring your motor has an exposed trim/tilt rod for the wedge to slide onto.
Q: My Yamaha V8 engine has two trim rods. Do I need two of these?
A: Yes, for Yamaha V-8 models (F300-F350), you must use two transom savers—one for the port and one for the starboard trim rod—for proper support.
Q: What are the included clips for?
A: The included clips are steering stabilizers, also known as centering clips. They attach to your boat's hydraulic steering rods to lock the engine in a straight position and prevent it from turning and shifting while trailering.

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.
