Correction...I'll be back on when he chimes in. Does Moderator mean you are the authority? I'll stick to what the Mercury man tells me. Swing by Annapolis and say hi Tom. I would love to meet you.
YUP! That's the one, I found it very educational as I am currently studying props for the repower of the Outrage 18 in refit. I found the section I was looking at :
Blade Count—Theoretically, the fewer number of blades a propeller has, the more efficient it will be. But as the number of blades is increased, vibration is decreased. For most applications, three blade propel- lers provide the best balance between efficiency and smoothness.
However, BRP/Evinrude engineers have created a series of four blade propellers that provide increased efficiency and a superior grip on the water. The result is improved acceleration and better cornering in all water conditions.
In addition, when operated in a surfacing application, a four blade propeller keeps more blades in the water for maximum thrust and efficiency.
