Is there a general consensus concerning RPM drop at WOT when switching from a 3 blade prop to a 4 blade prop of the same brand, diameter and pitch.<br /><br />I have a 14.25 X 17 3 blade prop that over-revs by 300 RPM. I want to replave it with a 4 blade prop (same manufacturer) of the same diameter and pitch. I am looking for better acceleration and better grip in the ocean, that is why I want to switch to a 4 blade prop. Will I drop 300 RPM at WOT?
