Well, the ship has been detuned to 48% design rated power. It had a nasty tendancy to put its near 3 foot diameter pistons through the cylinder head at 514 RPM. Our top speed went from just over 22 knots to 19.3 or something with a 52% decrease in power. Rumor is the sister ship killed an engineer who was standing next to the engine when it ejected a connecting rod through the side of the block.
