OIL PRESSURE SENDER R AND R

It turns out it was just the oil pressure sender on Charmed that had
failed, leaving us with a gauge on the engine instrument panel that
always read zero. It also turns out that Mastry is attentive and
provides wonderful service!

Once near Miami where we had reasonable access to marine services, we
called Mastry. A short discussion on what might be wrong left me
first thinking I would work on the issue myself, even though the
engine is in warranty. However, after studying connections and
guessing at the worst possible outcomes once I began removing things,
I asked Mastry to remain involved. A marvelous man came to the boat,
removed the sender, checked oil pressure with a mechanical gauge known
to read right, replaced the sender, and voila, all was back good! The
panel gauge on Charmed reads lower than the mechanical gauge that was
temporarily installed. It reads the same with the new sender as it
did with the original sender.

I am told Yanmars just don't have oil pressure system problems unless
something really goes bad, like getting salt water in the engine.
Charmed will continue to get new oil and new filters every 100 hours.
With good treatment and proper maintenance how many hours will she go?
