I would be amazed in Pampanito could "motor around on her own". First of all, as Darrin said, she has no screws! Second of all, if she is still Navy property, she is not allowed to unlock her shafts. Then there is the issue of cooling the main motors. Last time I talked with Rich, the sea chests were all welded over. That would make it tough to cool the main motors. The motors may be cooled with fresh water, but the fresh water still has to be cooled.
