Default 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?

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.
