Water take off DD 4-53

[Covequest]

I’m putting in a new water heater and want to have the engine heat the tank while underway. Does anyone have any pics of which ports to use to circulate water through the system? 4-53’s keel cooled.

I don't have a diagram, but the port to the heater is on the hot side of the thermostat and the return is just before the intake of the circulation. There probably won't be a blank port in front of the pump. You'll probably have to modify the plumbing.
