Turbodyne
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
A turbodyne is a device related to sublight starship propulsion. The number 4 turbodyne is sabotaged on the Celestra as part of a mutiny attempt, forcing the Celestra to drop out of the fleet until it could be repaired. It usually takes about two centares to repair a turbodyne (Take the Celestra).
