2014 250 sho . I'm only getting about 14 psi while running about 70 mph. Does this sound right. Coming out of a legend with 225 evinrude was about 25 psi at 65 mph. Boat has 26 pitch 3 blade prop and manual jackplate. Not sure of the prop to pad but water pressure seems low to me. Motor has 59 hours on it. Thanks . I'm turning about 5900 rpm.
