Turbo diesels

In the past small naturally aspirated diesels were the auxiliaries in cruising sailboats. Even on passage with a modicum of knowledge you could keep one going. Perhaps not all cyclinders but enough to propel the boat. You could have extra belts, filters and an injector feeling fairly confident.
Now virtually all recent boats have small turbo diesels. You would have difficulty even spec'ing a new boat with a naturally aspirated engine.

So the question to you wrenches is:

If the turbo goes, won't even spin, will the engine function at all? If so at what perecentage of its original shaft HP?. Are you better off physically removing it from the system? Given how expensive they are is it worth it to carry a spare(we carry a spare alternator)? If the engine can run without a turbo what does that do to the engine?
