Engine purchased from Charlie Willimas that is reputed to be Hugh Entrops Mercury four cylinder Mod engine.  Looks to be a KG9H or Mark 40H with open exhaust ( no pipes) a Mark 55H gear case, spray shield, not cowlings, fuel filter, non recoil starter and Mark 40H tower. We have not looked inside the engine but can only imagine what may have been done by the fastest man powered by an outboard at one time.
