GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
I have a 1989 Freedom Mach1 with 350 mag and Alpha 1. Currently running a Michigan 21p aluminum prop and im calculating about 38% slip. WOT is 5700 rpm and im hittin 47mph on gps. I believe my prop is disfunctional cuz im guessing this boat should be in the mid to high 50's on gps. Any help...
