Put a cmc break away plate on my 40 hp Yamaha last winter and I am very pleased with it. I think I found it online for bout $350. I put it on myself with a lot of help though. Performance marine at Sardis has them. Google CMC breakaway. I think the model is CMC ba 130. It works but it is only rated at 5 mph. I ain't hit nothing yet going very fast but I am sure I will eventually.
