I used to run my 32 Topaz with four bladed props because it reduced vibration at lower speeds, resulted in a slightly better efficiency at cruise speed and a shade better speed at cruise.

I now have a 330 Grady Express and I'm wondering if anyone out there has experimented with four bladed props for the 250 4 stroke yamaha's.
