Re: Acoustic Insulation for engine room?

I am in the same situation, I am in the middle of a repowering project and asked the forum for input on lining the inside of my engine compartment to reduce the engine sound.
Here is a link to the thread http://

I am going to use 1 inch sound absorbing foam I purchased form McMaster Carr. I can not give good reference as to how good it works because I never heard the engine run before I bought the boat. All I can compare it to is how loud is with the engine compartment door open or closed and how loud the engines sound on similar boats. just my .02

The compartment was originally lined with foam that has deteriorated over the 30 years.

Experience teaches us things we would rather not know.
