Thanks Blue Yonder and becnme for the insights. I was planning on some sort of thermostat on the coolant side with a return bypass valve if that is possible. So one the HW tank is at 140º it shut off. Not sure if possible or practical.
The QSC uses both sea water and coolant.
I'm looking to run engine coolant from my 2007 Cummins QSC8.3 to my Kuuma fresh hot water heater. The questions is where to connect the draw and return hoses on the engine. Can anyone offer any advice, photos, or diagrams on how to do this?
My last boat with Yanmar engines had this and it...
Thanks so much. Your ending bullet point made me laugh out loud. LOL. Yes the wife now retired wants to due just that. Our old 36' power cat only did 9mph. Soooo tired of that. The engines have just under 1200 hours. We have a copy of the 1000 hour maintenance report. Both after coolers...
