    Prop size

    Can anyone direct me where I can find or know the specs on what is supposed to be the prop on a 1991 ski nautique. Is the shaft 3/4" and the propeller diameter supposed to be 14"? I'm seeing 14x16 props on other 91's and I measured the diameter on mine and it measures only 12". The engine has an issue of revving high and I'm wondering if this is the reason.

      Are you using a 4 blade prop? I have an OJ Legend 13, the pitch is 16 I believe. Your 91 should be the same as my '97

        You might check out the brochures from CC listed here on the site. I'm thinking an acme 422 would be a nice upgrade for you.

          We have a 1990 Ski Nautique.

          1" shaft RH rotation.

          14X16 michigan wheel is the stock choice.

          1442 ACME 3 blade (13.25X15) is a great choice
          My favorite is the ACME 654 4 blade (12.5X15) this prop is geared more towards pulling heavy loads and wakeboarding. We use it for show skiing. pulling 0-15 people.
