MMI Fresh water cooling kit (side mounted)
This kit requires very little if any additional clearance on the alternator side, and will basically fit within the current profile of your Atomic 4 . The kit includes a MMI 501 sea water pump designed to use the same impeller as the Oberdorfer model 202M which is in widespread use on Atomic 4 engines. The heat exchanger is bulkhead-mounted and can be located in any convenient location. Belt, pulley, bracket, expansion tank and hardware included, hose sold separately by the foot.
