Just bought a 1997 31' Scarab and just wanting to see if some fellow scarab owners can share some knowledge. It is stock with twin MPI 502s and has 23 pitch 3 blade props. Just wondering if anyone has got any better performance out of 4 blade props or a different pitch. What kind of speed can I expect out of this boat. I haven't had a gps on it yet to check it. Thanks for any assistance.

Congrats on the new boat. I love mine. IMO, you should be in the low to mid 70's. I run 4 blades on mine, 26p. I am not a prop man so hopefully someone else can help you out.

Thanks for the reply. Does yours have the MPI 502s?

I have HP500's.
