My Maramu #220 also has the Perkins 4154.  I was originally thinking of putting in a more modern engine with a smaller footprint, but after using the boat last year I was so happy with the engine and think now that I would like to stay with the original.  The engine  has 3,700 hours on it, doesn’t leak any oil, seems healthy so I think it could have thousands of hours left yet.   Can you tell me what you did when you refurbished your engine?  I would like to install a large case Alternator  (or at least a HO alternator) ..if possible with a serpentine belt in the location once used by the mechanical refrigeration pump on the upper stb. side of the engine.  Do you know whether this can be done?

   Thanks Oliver for the mount information!
