I can think of at least one class of US Navy ships that had
one engine driving both ships, at least part of the time.

PG's (Asheville class I think) had two diesels driving two
shafts for slow speed crusing, and one Gas turbine which drove
both shafts through a huge gearbox.  The propellers were
controllable pitch though, so it could still vary (or reverse)
the thrust of the screws independently.
