I want to buy a new prop for my 19' Bowrider, with a 4.3L Merc. I want to use the boat for wakeboarding. There are so many different props out there. Can someone recommend which type or brand of prop i should be looking for?

There are so many different props and different boat setups that it is hard to just give an answer that would be 100 percent correct. I would suggest maybe a 4 blade or maybe a high five. They would give you the best hole shot for wakeboarding. What are you running right now and what is your WOT?

WOT is 4400-4800 RPM, dunno top speed, 190HP, 18', so maybe 40-50?

I meant what prop are you running now? Sorry! Your rpm's sound about right though.

What are you trying to accomplish with a new prop that you don't have now?

I need a new prop, because the old one is worn out, and I have heard that certain props will produce a better wake for wakeboarding.

High five<br /><br />Ron Hill five blade<br /><br />www.hillmarine.com<br /><br />I have a hill fiveblade on both my 4.3's and wouldn't change a thing for water sports.<br />I've tried all kinds of 3 and 4 blades and none even compared to the high five. The ronhill five blade is even better yet!<br />Good luck

If your on a budget try a 4 blade aluminum. You may need to go down in pitch 1-3 inches. I did this recently and love the holeshot improvement. Lost 3-4 mph in top speed but it's worth it.
