[QUOTE="Stephen Fournier, post: 511146, member: 35195"] I have a 1973 MirroCraft 16-foot Lake Fisherman powered by a 1998 Mercury Force 50 HP outboard. The motor mechanically is in pristine condition and after a 3-month renovation of the boat took it out for a spin. The motor WOT specifications is 5300 RPM, however with a brand-new calibrated tach the motor revved to slightly over 7000 RPM @ 31 MPH. Turns out the prop is a Mercury 48-73138-A40-14P, which translates to a 10 1/4" diameter x 14 Pitch. The boat weighs 350 LBS, total loaded with engine, 2-people, and gear maybe 800-1000 LBS. I did make sure the tach was calibrated properly, so I'm looking for recommendations for a new propeller size. Preliminary investigations are pointing to a 12-13" diameter and a 13-15 pitch ... any comments out there? [/QUOTE]
