At 22 min Sam is piloting from the flying bridge. Two controls are in the up position, two down. After Lucy joins Sam all 4 controls are in the up position without any apparent change in speed, wake, or sound of the engine.
At 1 hour 19 min Hanagan falls, then kicked by Sam into the engine compartment. After Sam dispatches two thugs Hanagan is resting comfortable against the engine block. The engine should have been extremely hot, certainly hot enough to elicit some response from Hanagan.
