Besides bblades who are other options out there that i can get good results from?

Got a solid 71.1 gps speedo and 70.9 phone gps today in the 272 with full tank and gear with 2 people. Stock bravo 28 pitch. Changed the rockers to 1.8 ratio and bumped the timing to 35 from 32. Those changes picked it up about 1.5 mph average. About 30hp gain. Changing the rockers gave me 30ths more lift and about 2 degrees duration. Not sure what hydro roller is in this but the lift matches the comp grind that is 566 566 and 224 230. That's a decent cam. Very happy with this boat. It's also getting a little over 2mpg cruising at 45 to 50. I have a 27 pich bravo coming to try and Brett is building me a labbed 28 also. I am turning 4900 and want to be around 5400. I think this boat will do 75 with the current engine power.
