That there is identical what mines propeller comparison looked like !!!
I ~ just like you .. noticed some performance differences and thot .. oh well !! I looked at mines old propeller and thot ... you not that bad. I gots to taken inventory on the dolla's I gots to spend fo the upcomin' DuckBird season and thot .. what the heck .. I'm gonna order a new one and thats when I figured out how worn mines old one was !!!!!
Note: When yore RPM's increase and yore speed slows .... propeller mite be worn !!!! When yore boathull don't jump up on plane like it used to ... propeller mite be worn !!!!!
Another Note: Propellers don't cost that dang much.
