Is the prop the original? If it was underpropped it would turn full RPMS but not get to full speed. Did you do your speed test in two opposite directions? Where you towing a large dinghy? Could current, big waves or lots of wind have caused the slow indicated speed? The knot meter should negate that if clean and calibrated properly. My guess is that the centerboards the main culprit.
