Can I reduce engine noise my insulating engine cover.
Mr Wizzard
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

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)

I have a 1995 3.0L in a 19' Sea Pro cuddy (Alpha 1 Mercruiser
outdrive). The engine cover has a foam rubber type egg crate design
liner stapled/glued on the inside. Pretty much a thin, very slightly
padded, exterior cover. It seems to deaden the sound pretty well. If
you have room under your cover the foam egg crate padding would be
worthwhile. I assume it is probably somewhat special to take the heat
generated by the engine. I am not sure that foil backed glass
insulation will absorb that much sound.

I would strongly advise against installing any sort of highly combustible
material on the underside of the engine box such as flexible expanded foam
or rigid expanded foam unless it was *completely* surrounded by high
temperature/high grade foil or covering intended for the underside of engine
boxes or engine hoods.

Install some thin sheets of lead-based sound attenuation material.
Here is a popular brand:

You're not likely to find anybody retailing this, (it's more typically
sold to upper end mfgr's) so a few suggestions:
1) Use the "contact us" link to communicate with the company and see
whether they have a dealer distributor in the area.
2) I believe you live somewhere in the greater Seattle area? If they
don't have a dealer here, what you may ultimately need is to find
somebody willing to order a small amount of this stuff for you. You
might have some luck at Fisheries Supply on Northlake- but go
downstairs and around the back to the section where the pros shop- you
may not find anybody who knows about this type of material in the
general retail store upstairs. Fisheries may even stock something
similar, but this isn't going to be a West Marine or Boater's World
sort of item.
If no luck at Fisheries
You may need to find a small shop who would be willing to order some of
this for you in order to establish some rapport with a new boat owner.
If you're on the east side, I'd check with Mercer Marine.
In Seattle proper, Pat's Marine Engines or Miller & Miller (more of a
general boatyard but very nice folks) would be good options for a small
project of this nature. If none of those are geographically convenient
but you are in the Pac NW drop me an email for additional
recommendations...there's a limit to the number of red flags the
anti-spam bulls will tolerate here. :-)
