Engine Box Insulation

[MC240]

Great looking job. How does it hold up against the heat of motor? Also, is it quieter than factory insulation?

I've never done a side-by-side noise comparison. At idle, you only hear the exhaust, not the motor. At speed all you hear is water and wind -- at least from the driver's seat.
As for heat, there's never been a problem. In fact, the exhaust risers just touch the insulation but mine never get hot enough to melt anything.

Looks like a good product.

Can anyone provide the product name of what insulation is being used in the new MCs? tks, mac

Gulp!!! That's very much like the product I bought from McMaster-Carr but WAY more expensive. Mine only cost $12.58/ft.

Here is the closest equivalent to what you once could find in Overton's catalog...

I think you'll need the 2 roll kit.

I've purchased this material but I haven't installed it yet.

Looks like good stuff at a inexpensive price. I sent for the free sample they offer.

I installed the stuff that "wheelerd" got from McMaster-Carr this past weekend and took the boat on the lake.... WOW! I was amazed at the different it makes. I started with just the burned up old stuff in it prior to the installation.
All you hear in idol is the bubbles and low rumble of the exhaust. I would highly recommend that stuff. I also sanded out the inside of the dog house first, to remove all the particles that may come lose and make the self stick not function.

Check out this insulation from McMaster Carr:

I just installed it in my motor box and was on the lake today for the first time with it. I used the 1 inch skinned self-adhesive stuff. Time will tell how the adhesive holds but it sure is quiet. I can hear the exhaust rumble better now.

Wheelerd, Maybe someone has asked this before, but how many feet do I need to buy of the 54" wide stuff for my 1994 engine box?

Thanks!

I ordered 8' and that was enough. There were a few scraps left over. Your 94 should be the same as my 91.
Do the main center piece first since it's the most complicated. Be sure to leave a bit extra on both ends -- better to have to cut some off after than have it too short.

I put the Mcmaster Carr material in and it works great.

As Sodar said I did the stuff he posted a link to. Overall I am very happy. The material itself is thin but the noise/insulating properties seem to be about the same as the original foam. The price was definitely right at a total of less than $75 including the insulation, tape and 3m adhesive. Installation was pretty easy and the material was easy to work with. One roll is just enough to do the engine box with just a little left over. I would recommend it.

BrianM - how is this holding up - do you like it? Any pics?
