Default 7.4L Merc engine

I recently bought a 2000 Z252 with 7.4 Merc engine. Engine cover is missing. The engine model is 7.4 MPI Bill. The engine number is OL621170. The Merc dealer in my small community cannot tell me the horse power. Does anyone know how to get this info. It has dual props. Thanks

    I'm not really sure what your question has to do with "Trailering and Tow Vehicles" ?

    In any event... 7.4 MPI had 310 HP at the prop. The 7.4 MPI LX had 330 HP at the prop
