I stapled some owens-corning fiberglass insulation onto the inside of my
engine cowl (it's plywood)- helped a little. I do have the padded vinyl on
the outside of it, which helps some also. It's still louder than I would
like. Have to use all 200 watts of stereo power pushed through my 4 Klipsch
bookshelf speakers (mounted fore and aft of the lounge seats pointing in) to
quiet 'er down at full throttle.... Not too bad under 3200 rpm's. (I've
got a little 2.1 L Volvo Penta 4 cyl gem)

So I got this cheap(er) 2005 Bayliner 175 Capi,
and I noticed that the Merc 3.0L/A-1 is louder
than other, and older Bayliners. I also notice
that some of the older Capi's w/ the 3.0L/A-1
has this foil-backed fiberglass insulation that is
taped to the inside of the engine cover. So I
got to thinking, can I insulate the inside of my
engine cover, and other surrounding surfaces
in, and around the engine compartment to help
deaden the engine sound? This 175 also doesn't
have a padded seat on top of the engine cover,
so there is really nothing to absort/deaden the
sound. Not a big worry, just wondering...

Thanks
