Recently got a pair of 2001 Yamaha HPDIs for a 23' Grady White Gulfstream. Anyone got a recommendation on prop selection? I know someone out there has this combination and I'm looking for a starting point; once I have props on the boat I can determine if they need to be changed.

There is a performance bulletin on Yamaha's web site that used 17 pitch props on that boat with twin Z150's.

Great Information!! Thanks a lot for the link. I now have 15 1/4 X 15s so I will test them first but it's hard to argue with that performance bulletin.Comment
