I currently have a 2004 Glastron SX175. The current prop on there is pretty beat up and slips like crazy while pulling tubers or even trying to take off quickly. I ideally wanted to go with a stainless steel 5 blade prop but im not seeing that as an option for the volvo pentas. Top speed means very little to me as i am on a very small lake and the boat is used soley for towing tubes / wakeboarders / and skiers. Anyone have any suggestions on props i should look at?
