Not a bad prop for the money. I run a 15.25 x 17 3 blade on my 18 cc/150 Johnson. It has more stern lift and holds in the corners better then my original OMC Viper 14 x 17. I can plane at 12 - 14mph with full tabs and hit 42mph at 5800 with a heavy load. The blades are thin but pretty tough.( I've opened a few oysters with no dings
). Next prop will be a 4 blade apollo or hopefully a Mercury Rev 4.
