Ok here we go. I have watch and read all the post regarding engine preferences. In the last 12 months I have owned machines with everything from single Kohler 16HP, 17HP Liquid Kawasaki Dual and currently 25Kohler HP Twin. In my experience the single Kohler was in application a smoother runner over the expensive Kawai Liquid. The 25 HP is unbelievable. Now I am aware the 25 had some growing pains. But they appear to be 2 production years behind them. And, no I dont have a rpoblem with Japanese motors. I have a small boat with a Suzuki 4 stroke outboard which is unquestionablt the best engine I have ever owned. But no one can sell me on the Kawasaki being significantly better in performance than the comparable Kohler.
