I have a 2022 30' phantom vee bottom, twin 300r motors. I've run 104mph with Dewald 5 blade over the hub props 32"x 15" x 17 degree rake @6400 rpms (the boat handled very good). I've run 96.8mph @6500rpms with a set of standard looking 32" full barrel bravo 1s . what pitch Max 5s would you recommend and ST or standard Max 5? I do not need lift in the rear. I ran a set of hill signature 32" x 15.25 x 15 degree rake and the boats handling (very bad) was not good 103 mph @6350 rpms. I would really like to buy a set of the 300hp cnc props. please help.

thank you ,

Jose, I have a new 32 Hellkat with 31' signature props 300 r's that ran 102 with more rpms to go. in cold wx the extra rpms will probably get me another 3 or 4 mph. I like this setup.

my 32 Hellkat ran 102 with more rpm to go with 31" signature props on a 90 degree day. with cooler wx I should get more speed out of it. good luck with the new boat. I am trying to post a pic here but no luck so far.

Hi Jose! Beautiful boat, being on the rev limiter, I would consider 33 pitch in the MAX5 ST. For the 300hp CNC Cleavers, you could step down to a 14.75 diameter, 18 rake, and go with a 34 pitch. The Hills are typically 2-3 inches of pitch stiffer than our cleavers, and run 4-5% more slip.
