    Rebuild does not deliver power of original A4

    Two years ago I bought a re-built A4 from Moyer Marine. Engine runs well, but never exceeds 1700 RPM under load and the boat (1981 Catalina 30) never exceeds 5.0 knots in the water. The old A4 would go to at least 2000 RPM (though I rarely exceeded 1800) and would move the boat at 6.0 knots. Same propeller, clean bottom, exhaust hose replaced this past winter. It was 5 kts/1700 rpm from the day it was put into service mid season after crankshaft died on old A4. The hull speed calculation for a boat with 25' waterline is 6.5 kts. Any thoughts?
