just had a used mariner 75hp p
just had a used mariner 75hp put on my 20ft pontoon. after checking different prop charts they tell me to use a 13x19 SS. that is what i'm running. i get around 3000 rpm top. do you thnk that i should look at a different prop or the height of the motor on the transom? i think that the cavitation plate is about 2inches or so below the water line.
