31 fastec propellers

Anyone out there have experience with the 31 Fastec?
I'm running 7.4 mpi's with 28 pitch and can only get 60 out of my current set up.
I was reading a old review and they were getting 70mph out of my boat... Any suggestions?

How many RPM @ 60 and how many blades on the 28?

I own a 2000 with 385 hp motors and run 74 mph all day with labbed 28s

You have 2 problems. The first is that the MPI motors put out less HP than the MAGS making your boat a 65-66 mph boat at best. The second is the loss of a few MPH. 28's are the best props for the boat but you could try 26's. If your loaded with gear and 3/4 tank of fuel and a couple passengers then 60 is probably all your going to get.
