    As long as it doesn't boil, you're fine.

    Just as important as the water temperature is the oil temperature. You don't want your engine oil running over ~240 F normally. So if you don't have an external oil cooler then you probably want to operate your engine around 200-210 F normally. Why? The babbit in bearings will flow plastically (permanently deform) somewhere around 280-300 F and you need some margin for higher loads (heavy throttle).
