Will do this is my third cummins, use to do motor swaps, 1st was a 1965 step van other was a 1963 Cadillac, guaranteed 500k motors with right maintenance. Don't know if its against jet boat rules but wish I could put one in a boat. Not sure there is a hull that would hold a 900 lb motor or a impeller that would get you to atleast 55 at 3k rpm.
