4 blade vs 3 blade outboard props

[Shawn Braquet]

Would changing my 3 blade stainless prop to a 4 blade on my tohatsu 25 help me get up quicker with a heavy load ( duck season)? Been bouncing the idea around and figured i'd ask the pros. I'm trying to get around getting rid of ole faithful to go to a surface drive. It's hard to cut loose 5500 these days, haven't figured out where all your money goes once you have a little one in the picture.
