Question: what is the difference in a 3 blade prop and a 4 blade prop?
Answer: 3 or 4 Blades? A 3 blade propeller usually offers top speed performance while a 4 blade propeller provides maximum thrust and smooth cruising operation. Four blades have some features of their own, though. They often provide more lift at the stern which will help accelerate the hull, especially if it is stern heavy.
