Just heard from the boatyard.
The manifold is apparently *not* the culprit responsible for allowing water to
enter cylinder #1. They tested the manifold up to 250 degrees and a certain
level of pressure (number I forgot) and found it to be sound.
Hmm. Head? Head gasket? The boat was running *perfectly*, so that would seem
unlikely.
Will keep the group posted, on the off chance that somebody may be able to
learn from my misfortune.
