2002 engine, cannot get RPM over 1400 when under load. If i reduce load (steer boat with wind) it helps. Heavier the load, more difficult to achieve acceleration. Usually RPM remains at 1400 unless load is reduced. Occasionally accelerates on it's own but I think it's due to un-noticed load reduction (wind,waves, current). Once RPMs exceed 1500 boat accelerates. Of course it reaches RPMs in neutral. Supercharger does engage. Recently changed fuel filters. Replaced supercharger 3 years ago.
