Question: Does anyone know if ships actually have "rev limiters" as shown in the film? Phillips had to keep ringing down to the engine room whenever he wanted to throttle the engines up a notch. I was always under the impression that marine engines that are used on boats are designed to be at max revs all day long?

Answer: Ship engines are run at a maximum optimal speed. The engine could go faster, but by doing so, fuel consumption could increase unnecessarily and/or you may have too much cavitation as the water flow is greater than what the propeller is designed for. But in an emergency, the engineers could make it go a bit faster than the maximum setting allowed by bridge control.
