I have a 2000 310 SeaRay Sundancer with twin 350 mpi closed loop cooling and want to hook up my heat exchanger on my hot water heater. Where is the proper connection for output and return line from the heater. I've got a mercruiser 22-72932a1 HOT WATER KIT, but the instructions do not show my 350 mpi with closed loop.
