kodiak kem equipment heat exchanger boat engine. Condition is "Used". This is a heat exchanger off a Kodiak marine Injun in a jet boat. This is likely either A496 or 350. I can't determine the exact model it came off of part numbers would be something like KM107 8:05 a.m. 10450 am 10499. Please matchup the fittings and placement of the outlet and inlet pipe. Does not include the radiator cap. But you can get one of those for a few dollars at the auto parts store this is a clean good looking not corroded up 4" heat exchanger
