Well I dont know what to do its a 385mpi with a 25 labbed it wont break 65 is this the wrong prop?

I'd think that 65 is about the best you can hope for with the 385 hp. Most guys with the 415 or 425 hp are only seeing 67-68 on a good day.

what rpm are you able to hit?

Well thats what i was afraid of its sitting on 5000 rpm I have a 23 it sounds like everybody has luck with them but like i said its maxed out on rpm
