    odd noise

    Are you sure its not your fly wheel touching anything ? That has happened to me on past jet boats at certain RPMs

    the same thing happened to my 454 and it was a flat cam lobe and a few bent push rods. it would do it above 2500 rpm's and sounded horrible. sounds like its time for a rebuild.
