Hi all I currently have I believe a 14 pitch prop I think it may be 10 3/8 x 14 I also had a 15 inch prop tell me what you think the best prop size would be I know I need around 5200 RPMs but I don't have an RPM gauge on the boat looking for overall just good top-end and would like to pull the kids on tubes once in awhile old props were aluminum and I am going to stainless thanks
