Mercury’s Bravo Three Props Produce Improved Acceleration
FOND DU LAC, Wis. (Jan. 26, 2010) – Mercury Marine today announced the release of new versions of the 20, 21 and 22.5 pitch front propellers in Mercury's Bravo Three propeller lineup.

These new propellers provide improved performance, including a significant reduction in time to plane. The three-blade rear propeller continues in production unchanged.

“The lower-pitch front propellers in the Bravo Three line-up have been redesigned from top to bottom,” said product manager Dirk Bjornstad. “These changes result in better acceleration across the board with light and heavy loads.

“The differences are most pronounced on boats with slower acceleration times. We've seen up to 8 percent faster acceleration with the new four-blade front propeller in heavier applications."

A Bravo Three propeller set consists of two counter-rotating propellers on the same drive. The Generation II Bravo Three propellers feature a four-blade front and a three-blade rear while the Generation I Bravo Three propellers used a three-blade front and rear.

“Our engineers have made refinements to the rake profile to provide the kind of holding customers expect with a four-blade front propeller,” said Bjornstad. “The new low pitch propellers ensure the complete line of Generation II models will accelerate and hold better than their predecessors.” Production of the latest revision of the 20, 21 and 22.5 Brave Three series began Jan 22.

Interesting article Boat Tech. If I'm understanding things correctly; the four blade low pitch front prop will provide more bite for out of the hole performance and low to mid range efficiency // While in return allow more drag reducing mid to upper range performance. ...Ron
 
They didm't mention whether that will be standard on new Bravo III drives. I assume it will be but I wonder how soon before we see them on new boats. I also wonder how much that prop will cost for those that want to retrofit one on their current Bravo III drives.

:huh:
 
Has anyone tried these yet? I am looking into doing this since I really think my set up is wrong. Both of my props are 16X20 (came from the dealer) and for some reason it seems like the cup comes out of them after about three months. Yank them off, get them worked and it does fine. Then after about three months bottom end performance decreases and planing becomes difficult again.
 
they have been out for a while;
i looked at them last summer when i did the B3 on the weekender but passed because i wasnt sure what to start as far as pitch, and didnt want to spend that much not knowing what pitch prop set to start with
