Has anyone used an exhast manifold wrap in your engine room?

Seems you can not get any good asbestos any more so the best wrap on
the market is DEI fiberglass wrap:

Seems like the way to go..any other suggestions?

It's actually on my list of things to do... check the exhaust pipe for
damage. According to the previous owner, it wasn't replaced with the highest
quality, due to lack of availability of the replacement part and time
constraints/location of the boat. It seemed fine when I looked on the
weekend, but I didn't unwrap the insulation.. it was wired on. The previous
owner claims that it's "easy" to undo the wire wrap, but I didn't have time
to try it.

When it starts to leak black stains may appear.

A CO monitor will help ensure you breath no serious monoxide.

Running the engine room ventilator is more insurance any exhaust
leakage gets blown out of the boat.

The aspiration of the engine may also reduce atmospheric pressure near
the engine by pulling air into the compartment, more assurance that
minimal exhaust leakage is recycled through the engine instead of
being blown into the boat.

You can check air movements around the compartment boundaries by using
a smoke source. These may become more apparrant if you take off the
alternator belt to study airflow.

Peeling the exhaust is messy and irritating and you would want new f/g
tape and wire. Mine was easier to relap using individual wire ties
instead of trying to do a long spiral siezing. I got the f/g tape from
an engine performance car part dealer. Enough to do the boat twice or
so for 70 bucks. When I redid the engine exhaust, I used 1-1/2 inch
iron pipe and fittings, with some welding for the bellows, another
automotive part. My exhaust manifold accepts a 1-1/2" nipple.

I installed a CO monitor, and so far haven't had any problems... even with
the engine cover off, something I don't normally do.

We were real lucky when our exhaust riser broke recently, I guess. It
must have had a small crack for quite awile, but wasn't apparent for
the reasons Terry outlines. I've never quite believed in CO sensors,
but think I may just install one now.
Seems the motor mounts are worn out on Arabella and the increased
vibration probably caused the pipe to go-though no doubt it was ready.
This is the most helpful thread I've ever encountered on ASA! Scary!

You can cross post if the subject matter fits and both groups would be
interested.

How the cruise going? Where are you now?
