Mercury KG4H serial tag 595291 with KF7HD crank case serial number 403335 and a Mark 15 cylinder block serial number 718871.  Mechanically restored with new rod bearings, rings, fuel line, plug wires, spark plugs and impeller.  New throttle connector and some minor hardware.  AJ32A Carb without choke or choke linkage. The engine has nice sprark.  The multi hole gear case turns over smoothly but is tight due to new impeller.  The gear case has nice threads and has been shaved on the sides by a prior owner. We have not run this engine but there should not be any reason it would not run.
