First, everyboat is different, some are close to others, but the general concensus, is there is no general consensus.....That said, be prepared for several different ideas as to what is right. I could give you numbers that work on a Revenge, but I am unfamilure with Sangers. So, I won't even guess. Be patient, someone here with Sanger experience will step in and get you in the ballpark for your boat, then you can dial it from there...........MP
