Twin Mercruiser 350 with Bravo 3 Duo Prop outdrives
I was told today that there is a correct way to install the duo props on my Bravo 3 outdrives for the best horsepower, torque, and fuel efficiency. I was a little surprised but I thought I would ask.

Can someone please fill me in on whether this is true or not? And if it is, what IS the correct way to install them or "Index" them?

Thank you
