[QUOTE="Pappy, post: 426764, member: 3278"] [size=5]The answer is "maybe". In general a 4-blade will run a bit higher, come out of the hole better, use less fuel at cruise and get better speed at lower to mid-range RPM. The 3-blade will or should produce better numbers at WOT. All of this is contingent on the props though. My comments are based on V6 knowledge and application with propellers produced from the same manufacturer. The 4-blade will also produce better numbers at WOT on a boat that typically takes a lot of trim to get the bow up and out of the water at speed. Blade area is to your advantage when blade area is needed. [/size] [/QUOTE]
