The OMC bracket works and will handle the Yamaha four strokes. Personally, I got tired years ago of hanging over the back of my boat and lifting those hydralic brackets. I have a 9.9 Yamaha and it was heavy. I invested in a electric hydralic lift from Islands Marine Center eight years ago and have done nothing but flip a switch to lift my outboard since then. It works great and I've never had one problem and it gets heavy use every year. They are pricey. At last check I think around $1,000 for the bracket and motor but you will never regret it if you have low back problems.
