I was using a 28 Raker before Russ F. sold me a 27SRX. One thing I can say is DON'T have any cup added to that prop. It will kill your RPM'S. The Srx, on the other hand, responded well to DAH propeller adding cup. I saw about another 3-4 mph. Overall the difference between the Raker and the SRX was about 7 to 10 MPH on the top end, depending on the conditions. You probably won't pull up a skier with it, like you could with the Raker, but the performance is miles apart. While the Raker is not a bad prop, you probably need something a little more performance minded for speed. Chet (77VIPER) could probably point you in the right direction, or if your looking, try Scream&Fly.
