Just purchased a 2014 Sun Station 2250 GSR with 115 Yamaha. Will use for pulling grandkids on tubes and slow cruising. What would be the best size prop to use? Also would a stainless be worth the investment?
You need to provide a lot more info if you want a real answer to your question such as current prop make and model as well as its pitch and diameter, your current GPS-verified top speed and rpms. Also, do you have 2 or 3 tubes on your boat?
