I had the ACME 422, now it's my backup, I got the ACME 480. It's 13" dia. x 12.5 degree pitch for 1" shaft. I got a 95 sport nautique and load it with a little over 2000 lbs in the back, about 800 in the bow, and 300 in the ski locker. Gets on plane fairly easy and the wake is awesome. www.propmd.com
fixed my old prop for free when I bought the new one.
