i have a 25 mirage plus on now im turning 4600 r at 65 mph on gps running 502 prob 415 hp I feel i should be running faster would a 4 blade be better any ideas new to game

Your rpms should be around 4900 I believe. Best bet is to send your prop out to get lab finished. You should pick up 200-300 rpms and a couple mph

Try Drocks suggestion or go to a labbed 24 bravo, you should be around 70 maybe a touch higher, how many hours on your motor?

I just sold my Raizor last year. I've tried Mirage Plus, Mirage, Bravo 1 and Rev4 props . The Rev4 was the best props for this boat. I ran both a 23 an 25 pitch with my 454 mag MPI. The best I ever got was 68mph with a few gps spikes over 70. let me know if you have any questions and I'll try to help you out.

thanks for the help prop was labbed , i can get 67 gps but not consistent the hours are 283
