Confused new owner of not so new 1987 Hunter 28.5. Please help! I do not understand the closed cooling system for the Yanmar 16hp. There is a remote fill line in the starboard hatch in the cockpit. It is full of antifreeze all the way to the cap. my questions:
1. Should it be that full? Concerned it will expand with motor running.
2. Is this the only coolant fill for the engine?
3. Should the freshwater tank be full? I ask because it looks like there is a heat exchange between the engine and the hot water heater.
Thanks for any advice to this novice!
