TOPIC: Engine Cowl Sound Insulation

I am restoring a '61 Evinrude Starflite III. The cowl was lined with a 1" foam insulation. Does anyone know where I can find a suitable replacement product?

West marine also sell it

One inch foam rubber with a plastic film on one side from an upholstery shop would be good.

The original stuff sure makes a mess when it starts to disintegrate, huh!? I had looked at DynaMat, DEI, and some "house brand" stuff on the Summit Racing site, but I think I like the Jamestown Dist. stuff better. Besides, support the business' that support our site, right!?
