QSC 540 water heater connections

[Grant Johnson]

Guys,

I have a 2006 Sea Ray 48 with QSC 540’s installed. The water heater for the boat is not connected to the engine to heat it up without using the electrical to heat the tank. The stock heater has the provision but Sea Ray I guess chose not to hook it up. Is there a place on the QSC to tap for hot water to travel through the water heater coil and then back out?

Thanks for the feedback.

The article shows the location of the ports, can someone help me with the thread sizes please. Also is there any need for a thermostat to regulate the hot water to the tank? Thanks
