I recenty purchased a 25' suntracker partybarge regency with a 115 hp Mercury Optimax outboard. I used GPS to get my max WOT 5700rpm speed of 19 MPH. I have read through everythread on this site and it seem I should be doing better the 19 MPH. I looked at the prop that came on the boat and I cant read what size it is because there is build up on it.
My question is should I be doing better than 19 MPH? If so what size prop should I be using? I was thinking of a 14x13. Should I get a cupped blade?
This is my first boat and I am kind of learning as I go.
