I tried 34 four blade merc cleavers on a 32' skater. I had to have the addendum cut off because when you let off it felt like you were hitting the brakes, I also had the 34 merc four blade cleavers made into et's by Bblades rounding and cupping the blades (like a blaster) to reduce stern lift. They worked well but not as good as the Dewalds.

Dave Dewald has been perfecting the 28 Skater prop with the aid of Shaun Torente for more than 10 years. I feel that is why the are superior to all other "generic" props. The four blade ones are a lot smoother with almost no vibration. His new to last year CNC ones out-performed his earlier ones by 4 MPH on my boat.

Mine were built for Shaun Torrente, by Dave and are Fast Props!!
