I just bought a 87 3.0 4 cylnder 17ft boat. I need a new prop but dont know what would be the best prop to buy. we are going to be wakeboarding behind it the most and the rest just playing around . I dont care for top speed. I was looking around and can buy a 19 pitch oem for 140 and a ss for about 300 plus. My question is , is it worth the extra money to go with the ss over the oem? Also would a 19 pitch be better or a 17 pitch? THANKS
