Hello all. I am going to get a new prop for my 74 Johnson 50 twin. It is on the back of a 74 Starcraft 18 ft Super Sport ( I know it should be running a larger motor). It is currently running a 15 pitch aluminum but I don't think it is reaching top RPM and gets me going at about 24 mph, also when I have another couple in the boat, it won't get up on plane.
Would anyone recoment a 13 pitch and should I go to a 4 blade or stick with a 3?
Thanks
