RPM-speed tables
ALCON may have found the information already, but...
The shaft RPM tables are on pg 14 of the Type VIIC manual at uboatarchive.net. There are also some photos at uboat.net of U-995's engine order telegraphs and RPM-speed table placards.
The engine RPM and shaft RPM are the same in the case of the subject U-Boats. The propulsion plants were (are, actually...as far as the surviving museum boats go) direct-drive with reversible diesel engines and propulsion motors; there are no reduction gears.
