best prop for 225 di evinrude

[rommel]

i currently have a 19p aluminum 3 blade on my 2050 sportfish. it will run out to 53mph with normal load. i noticed the other day that it was running close to 6100 rpms though. i'm thinking maybe a four blade sst 20p might get my rpms down to the 5800 range. any ideas?

If you are running 53 mph with an aluminum prop at 6100 rpm then I would go to a 19p Tempest. What is the diameter of your of your 19p aluminum prop?
