"Big Ear" Choppers work well on heavy bowed boats because of the large blade area. They have great lift. I have tried mine on several boats "heavy" boats with good results. There are a lot of good props out there. The chopper just happens to be my favorite, but I also like the trophy, Laser, and the original Tempest. These are just my opinions and experiences. </p>
I have a 25 tempest plus that I modified the flow torque hub to fit omc as well. (I am too cheap to buy the other kit).</p>
I second Performance Propeller. If you currently have a raker, take it to them and have them add some cup to it. You will be amazed at how much better it will run. They will be able to get you in the right direction. JMO......</p>
