One of my buddy has a 1994 Open Bow Ski Nautique with a 351w in it. It has the factory three blade prop on it with these numbers stamped in it OJ 14 16 Cup! What do these numbers mean? Which rotation is this boat? What is the shaft size? Is this the most efficent prop for this boat,we wakesurf,wakeboard and need to be able to cruise in the upper thirties at least. It does everything very well right now,just thinking about a new prop as this one has touched a few things here and there through the years
! Thanks for the help guys!
