I have a 30hp 2003 Tohatsu short shaft on a standard layout gheenoe LT25. Tohatsu states 5250 - 6250 rpms on the specification sticker. Currently I am running a 12 pitch Solas aluminum prop at 5700 rpm. I am considering trying a new prop. What pitch would be good in four blade stainless? Currently there is a power tech 4 blade stainless 11pitch asking price of $200 I can pick up used and am wondering if it would be a good choice. Also, if I went stainless three blade what recommendations would you all have? Thanks in advance!
