I had the same boat and engine/gear combo. It came from the factory with a Mirage 23P Stainless Steel prop. Engine maxed at 4800rpm and ran 55.0 mph (indicated and GPS) Could be your prop is still the wrong diameter.

I owned a 1996 16 with the same setup as yours with the 23P mirage. Helped my buddy with the annual maintenance and spring shakedown on Saturday. Boat still runs like a champ at 55-60 at 4800. Replace the prop and enjoy your boat. Let me know if you need the model number on the prop and I will ask my buddy to get it for you. Todd

Johnzi - the Mercury QSS prop is not one of their better performing props. The Mirage Plus suggested by Mark and Todd is!
