First of all, if the prop doesnt have major dings, clean up the edges with sand paper – do not use a file! Next, adjust your current set-up for the best performance. My suggestion is to measure prop to pad and start at 3.5″s below and slowly increase 1/4″ at a time until you 1) hit the max RPM, 2)lose speed/gain RPMs or 3)lose water pressure. After this, come back with your #s and you can get a better recommendation.
