Robert,
If you ever do decide to install new insulation I can share a few tricks to make it easier as I re-insulated the compartment in my C&C 32 last year. I used material purchased from Defender which is reflective containing foam and rubber and lead which is impossible to drill holes in for mounting and the compartment does not allow room to swing a hammer to mount with the usual mounting hardware. If I ever did it again I would glue the stuff in. Anyhow, I tore the old stuff out and left in the mounting screws then made cardboard templets of the foam patters and put a small amount of paint or magic marker on each screw head and pressed the cardboard in place. This gave me screw locations for the pattern and insulation. I then laid the pattern on the insulation to cut to shape and transferred the holes to the insulation using a small soldering Iron which burned through the insulation foam and rubber. A drill caught and twisted the foam and got caught messing up the insulation and took a lot of time removing. Then remove all the screws in the sides of the engine compartment and mount the insulation with fender washers on the old screws. I then used metal backed duct tape on the ends and any joints of the insulation. See Arpeggio1984.info, web site under Projects 2013 for results. Looks and works good!

Update: Tonight I removed the sound insulation from the sides of the engine compartment. Let me tell you - it was a dirty mess. Surprisingly, it is possible for a substance to be both dusty and oily at the same time. On the bright side, after removing the old, crumbling insulation I was able to give the little Yanmar and the engine compartment a good cleaning. It looks 100% better now and I think it will be easier to keep the engine clean. I can't report on the noise yet as I'm waiting on an exhaust elbow at the moment. Even if it's a little noisier under power, I think that it may be worth it just to have a little more room in the engine compartment (it's amazing what an extra couple of inches can give you in a cramped space) . On the other hand, if the racket proves to be intolerable, I'll report back with a warning to others who might be contemplating taking the same steps. Thanks to everyone for the helpful feedback.

I have replaced the old, crumbling sound insulation in the accessible parts of my engine compartment with new sound insulation from West Marine. However, there is almost no room on either side of my Yanmar in my 30 MKII. Getting new insulation in along the sides is going to be very difficult. I am contemplating just taking out the old insulation from the sides of the engine compartment and going without. Does anyone think this would be a big mistake?
