Since I have all of the water system out I thought I may as well look at the engine and how it connects to the hot water system. What are these valves and pipes for at the aft end of the engine? Should the Hot loop from the engine first flow to the HW heater and then back to the exchanger? :confused:
I am sure I read something about this.

Ross,
It sounds like your boat is plumbed like Julandra was when I first got her. All sorts of extra plumbing near the aft end of the engine, including a gate valve. After checking with a number of mechanics and Universal (now Westerbeke/Universal), I ripped out all the extra "stuff" and plumbed it like you described (and how it should be and how newer engines are plumbed). I never really got a clear answer as to why they were plumbed that way from the factory. It had something do do with being able to change the flow to the water heater.

I agree with Tom. The way our HW heater is plumbed is from the freshwater coolant pump and thermostat housing to the HW heater in & out. Simple.

Just an FYI based on your hull # I had a Cat 30 1984 that was plumbed that way and it allowed you to bypass the water heater. Why? Can't answer that!

I think the answer is simple. Remove what is not needed and use the KISS rule. Thanks for the input. It certainly makes decissions easier.:D
