I thought that the flare forced the water out on the blade to make it "HOOK UP" or "BITE"....without the flare the water just roll off the blade and "BLOWS OUT" or "Cavitates"....Or as Dan Schwarzenbach used to say, "Calvokate." Lords know you don't want to "Calvokate".....especially in rough water...
OMC used a reverse flair until Merc's patent ran out...The original patent may have been by Dick Snyder at Mercury.
