Sorry I did not see your reply to my post. I have a 50 hp 2 stroke Johnson.(my boat is a little different-26M). Since we have the "same" motor I would love to Know what pitch and diameter you are using. In my quest to find a good prop I would like to try 2 or 3 props instead of 4 or 5. I saved everyone's input and appreciate it. Thanks Jeff. Try bigger Submitted by Bob on 02/09/2005 at 06:08AM regarding MacGregor 26X I have a 26X with a 1996 Johnson 50 2 stroke. My prop is 12 inches or bigger. I easily get 22-24 mph flat out with no ballast. With ballast I can still get 18-20.
