mph dose'nt match rpm

Hey Guys,
I'm trying to figure out what is going on with my boat.I have a 06 sunsation 288 with a stock bravo 1 26 prop. I was dialed in last year running 71.2 gps at 5100 rpm. That is about as good as you can be according to the prop calculater.At the end of season I broke a blade off my prop at idle speed docking in a bad spot. I had a new bravo 1 26 spare and put it on.I ran the boat the rest of the day and did'nt take it out until this year.Now the boat runs 65 and is hitting the rev limiter. I thought the trim indicator was off and I was over trimming ,but that is not the case.The only other thing that I have not tryed is a different prop.I have a new bravo 1 26 I plan to try just to rule out the other new prop.I would'nt think a new prop would be that far off.Any ideals on this one?
