As with anything, there's a risk. There are a huge number of boats with domestic hot water off the engine. IMO, think rhe risk is pretty low. If the heat exchanger in the water tank fails, you probably aren't going to have a quick engine failure as the domestic water pressure is higher than the coolant loop pressure. So the engine isn't going to be without fluid in the coolant loop.
