Default Re: Model A Marine Engine?

Most marine engines used on the ocean have a heat exchanger where the raw water cools the coolant used in the engine. This keeps the engine from rusting up to become an anchor.

If this engine was used on a lake then it could have just used the fresh water for cooling. It looks like the coolant went through the exhaust manifold before entering the engine. That makes sense as otherwise the engine would never get to operating temperature.
