I was driving down to the CBBT before Xmas and followed a guy with a center console and a Yamaha 250. Must have followed him for a couple of hours.... Anyway, his engine was supported by the trim locks, you know when you trim the engine all the way up and flip down the locks that keep in place. His engine was wagging like a tail of a dog and I kept thinking that has to be bad for the transom with all that weight bouncing up and down. It looked like his engine could have snapped off at anytime. (His boat looked pretty new and was a highly respected brand, not some old junker). The purpose of the MY Wedge is too reduce that kind of weight on the transom. It is basically a 10"-12" cylinder made of hard rubber with a PVC pipe on the outside of the rubber. There is a hole in the middle of the cylinder that goes around a trim rod. Slide the wedge on the trim rod, lower the trim until the rubber contacts the engine and call it a day. The engine is supported at a much lower angle than if using the trim locks and there is no pressure on hydraulics of the trim rod itself. The rubber cylinder takes the weight of the engine and absorbs road shock.
