I'm wondering if I'm correct in my thoughts on Plumbing my jet boat. I'm going to run a line from the pump to the pressure relief valve and from that valve up to a tee fitting and into the water pump ports. Two lines out of the thermostat housing, one dumps overboard one has a valve on it to control water out. Is this correct or am I missing something? The line coming from the thermostat housing with the valve on it will be going to my header control valve. And yes I've looked at plenty of pictures and diagrams on this.
