Hey guys, what is the rule of thumb on going from a 3 blade prop to a 4 blade prop. I was running a Mercury Thurster 3 blade 25 x 14 and I hit something on the boat ramp when Lake Lanier was so low and cracked 1 ear of it. I have a 26 x 13 1/2 3 blade but it's a small hub. Think it'll work??? I had the Thruster welded by a friend but it has cracked again. It's cracked on the back side for about 1/3 of the ear width. What do you guys think?? Thanks; Robert emoScratch
