[C320-list] Engine room noise

[amshd2 at aol.com]

I have hull #30 and lined both sides of the engine compart with the 1 inch WM Noise Control Barrier Material Reduction. WM Model # 216866.  It was easy to work with and did a great job. I also used gasket material and a flat sound mat in the aft berth from Soundown.  They also sell the same type of stuff WM has may be able to get a better price. They are great to work with and made some good suggestion.   http://www.soundown.com/index_Marine.htm.  I can not tell you how big a differanceboth made.

I have the same vintage boat with the Perkins M30. The previous owner lined the 
compartment with 1.5" x 12"  thick foam & mylar film insulation panels. It works 
very well. WM sells similar material in rolls but the adhesive backed squares 
would be easier to install. Not sure where to get them though. Harbor Freight? 

Vibration at low RPMs is a problem. Our Perkins manual specifies 1100 min. and 
any lower than that causes it to run too rough. We tried to set the idle lower 
but it wasn't happy.
