I just purchased a pair of labbed Hydromotive 29 pitch P5X through the classifieds. I will be very interested to see how these work. 32" B1's were definitely not the prop for my boat. I hit a wall around 4000 rpm that I had to nurse the boat through. I am guessing that the small M1 prochargers were not making enough boost at that point. It was also taking a little longer to get on plane with the Konrad drives. I'm looking forward to trying these out. I'm not so interested in top speed.

I think the rule of thumb is 500 hp on TRS drives.

I chased an RF signal for a whole season on my drag car. drove us freakin nuts. I had just changed the cam and was sure that was the cause. Changed back same problem, So we checked valave adjustment, fuel prump out put. all kinds of things , I even called MSD and sent them my box. They sent it back said it was fine.
eventually I got the RIGHT guy on the phone at MSD and he said that RPM is where Rf kicks in. Re wired and shielded Problem solved.

I am not sure what ignition your using but that 4000 RPM number is kind of a majic number for RF signal problems to show up with MSD ignitions.

ours originally had 330's I think and ran mid 70's when my buddy owned it, If Memory serves me right but that was almost 20 years ago so I am not sure.
Plus there was only the dream O meter back then no GPS so who really knows.LOL
