No.
If the deficiency is with propulsion that’s bad.
That if ignored will cause loss of power.

[Chad C. Mulligan]

Three months later the USCG inspection must have found that the ultra-minor "deficiency" was fixed. How hard is that to understand?

Looking at other reports, it seems that the ship may have lost electrical power....nothing to do with gauges or thermometers. That might have affected rudder control. Nothing to do with propulsion. Another (unconfirmed) report says they had reversed the props in an attempt to stop, so the propulsion systems must have been working.
