M-Y Wedge Trailering Supports have been designed to enable safe highway transport of an outboard powered boat with the motor in a tilted position. The M-Y Wedge prevents the outboard motor from returning to a vertical alignment and possible contact with the road surface. This made in the USA product is compatible with Yamaha, Mercury, Evinrude/Johnson, Suzuki, and Honda outboards with single ram trim and tilt assemblies. The M-Y Wedge single ram support easily installs around the trim and tilt ram. Measuring 5 inches in length, the M-Y Wedge can conveniently be stored in most boat hatches and lockers. Constructed from EPDM rubber, the M-Y Wedge is virtually indestructible and is UV and saltwater resistant. Feel free to inquire with any questions.
