Perhaps a battery charge off the one prop like the Uboat did? |
Don't think so as the U-Boats only had two engines and one did the charging while the other turned one screw, then when batteries charged both engines turned the two screws. US Subs had four engines and both screws turned during a charge as another engine did the charging ( also was coupled to a screw but not when charging ).
Hold the phone, after some checking maybe you are right about the S-Boat as according to this they had only two engines, but it looks like they could charge on the surface and drive the screws at the same time. Read here ( This is copied from part of a below link) :
Simon Lake's last S-boats…the so called 4th group USS S-48 (SS-159), USS S-49 (SS-160), USS S-50 (SS-161), and USS S-51 (SS-162) were powered with two side-by-side Busch Sulzer 2 cycle Model 6M150 diesel engines of 900 BHP, each. USS S-48, after rebuild, had 2 Busch Sulzer 2 cycle diesel engines of 1,000 BHP, each. These were direct drives; mechanical power from the engine through a clutch to the dynamo (motor/generator) through another clutch then to the propeller.
As for what engines
Your SHIV Subs are using is probably listed here:

Well I know for sure that this USS Drum truns both screws while charging Then again it's not an S-Boat either.
