14x14 original 3 blade prop, 4100RPM = 37/38 MPH is this close???
Haven't used the boat a lot lately, thought it used to rev higher and go faster????
Usually don't run above 3000 rpm and 26/28 mph when going on an ice cream or beer run. Could the tach be out, checked speedos with GPS, pretty close usually.
Still one of the best looking boats on the lake, we'll be like the Golden Pond folks in another 25 years with our antique boat!!
