Need a new prop for -
Crownline 206LS
Mercruiser 4.3L MPI 220
Alpha 1
1.62:1
WOT 4700
50mph
slip = 9%
current prop is Mercury Alpha 4 14" x 20" (four blade AL.) which they no longer make. I want to stay with 4 blade or 5 blade as the boat is slow to get on plane ( smart tabs helped). What have people had success with? Do I go up in diameter and down in pitch? Thanks

Hi
if your speed is gps...I can only advise that you are doing incredibly well as you are. Especially for a 4 blade.
Id maybe just check you are certain about your exact numbers before you open the wallet to splash out.
I know of a regal 1900 with fastrac hull. 4.3 mpi and 1.62. It has a 21” spitfire 4 blade. It will hit the limiter at 4950 and about 50 gps. You are doing really well as you are I think.
