Anybody have any experience with labbed props from Mercury? If so what did you see for performance gains ( rpm and mph)? I am looking at a labbed 28p Bravo 1 prop. I ran a stock one but I could only get about 4600 rpm on my 502 mpi. Would a labbed one bring me up to around 5000 rpm? Thanks for any input.

You should gain 300 rpm and 2-3 mph sometimes more on the speed with the right boat.

200 rpm and 2-3mph, agree.
