  • SS Prop for a Chaparral 220 SSi

    Looking to upgrade from a four blade 14x20P aluminum prop to a four blade SS. Power plant is a stern drive Merc 5.0 MPI with an Alpha One out drive. Dry wight of the boat is about 3,900 lbs and can get the boat up to 51 MPH with 4,900 RPM at WOT with only a few people on the boat. I have read that when going from aluminum to SS you generally pitch up is that accurate? Looking for good overall performance with hole shot and ability to get the boat to plane quickly as the top priorities. Any good recommendations on props or sizes?

    Thanks!

    your numbers are not bad. is that from GPS or speedometer?
    I'd probably go 21 pitch Mirage Plus if your looking for a good all around 3 blade stainless, pretty fast, cruises well.

      It was from the speedometer, i haven't checked it on GPS. Does the Mirage Plus come in a 4 blade or just a 3 blade? If going 4 blades would a 21 pitch still the best option?

        the Mirage Plus is a 3 blade.
        If you want a 4 blade, I'd go with the PTZ4 from Powertech.
        pitch will depend mainly on the GPS speed.
