Re: [OMC-Boats] Insulating engine

I hadn't even stopped to consider that foam board wouldn't work to
dampen noise. Ok, so foam board it out. If I stumble upon something
that would work better, maybe I'll try it. But it almost sounds like
it's not worth the time. What about some carpet or something?

I guess I'm getting to the bottom of the barrel with tinkering on this
thing so noise was my next tackle. So far I got my cooling issue
worked out, and got my pisser working again. It was clogged, so not
related to my cooling issue. But I guess it's kind of good. Had it not
been clogged, I would have never suspected a cooling issue. Installed
the clear lines, found and fixed my cooling issue. Now I have the tell
tale to show me if I have any more issues. Let's see, what else have I
done....

I installed a stereo and a couple of speakers. Had some nice speakers
from a car audio system I used to have. Made an enclosure to hang the
head unit below the glove box. Mounted speakers in the plywood kick
panels under the dash on each side. Added a master kill switch to it
so I can be sure it doesn't drain my battery during storage. Sounds
great. Removed the extra brackets for things I'll never use like the
goofy Loran thing and the old ship to shore. Cleaned up everything and
made it shiny again. Oh and the glove compartment was bugging me. It
was lined with what looks like old fashioned cork gasket paper. It was
flaking and I couldn't put small items in there for fear of losing
them among the cork dust. Plus, it was deep and dark. I hated it. I
relined it with light gray indoor out door carpeting and just for
giggles, I added a light. So now I have a nice soft, well lit glove
box. Also replaced the v belt. So no more belt squeal. Yay.

Waiting for the convertible top to come back from the seamstress. The
top has never been up but the zippers rotted off it, so they need
replaced. I also have the side panels for it and the rear piece, they
were in the previous owners attic, never removed from the original
packaging.

Next on the list is trying to get the handrails looking good again.
They're dull and pitted. Metal polish won't do it. I'm going to attack
them with some #000 steel wool and see what happens. Then while it's
stored this winter, I plan to take out the table thing and tear it
apart and rebuilt it with the original metal frame and some new wood
inserts.

Speaking os possible performance loss, are there any easy bolt on's
for the V8 Buick that will boost performance a bit? 4 barrel maybe?
