I'm considering adding a pyrometer to my boat.. the current temp gage is
for water, and I've heard from several sources that if there's a sudden

Something like this: http://www.livorsi.com/catalog/pyrometers.htm

However, I'm concerned about putting a hole in my exhaust manifold.

Anybody done this? Tips/tricks/things to watchout for?

If you don't want to putting a hole in the exhaust, you may wish to
consider an infrared thermometer. It is as accurate and measures the
temperature from the infra red radiation from the heating device, Exhaust.

Hmmm... well, a quick search seems to find that most are very expensive
compared to the kind that require a hole. Also, they don't seem to have a
standard type marine gauge. If you know a source, let me know.
