XR6 repower prop selection

[eric fairbanks]

Hello, I am replacing the '95 115 merc, with a new 2002(leftover deal) 150 merc. The shop doing the rigging said to contact Ranger for the best prop. selection and mounting height. The boat is a '95 Ranger VS690. Shop said they could do an educated guess, but the manufacturer has many more hours and $ in testing. They said the Merc. site would not be as accurate. Well, Ranger said 4th mounting hole, and use a high five 21 prop. The Merc. prop. selector calls for that prop. in pulling skiers. I only fish walleye. I was thinking more like a 23 pitch, 3 blade stainless. Any ideas or experiences with the high five?
