Inboard Outboard Boat engine
« on: August 06, 2005, 03:28:49 AM »

I'd like to make my inboard/outboard boat engine as quiet as possible.  I'm trying to educate myself about the various products that will work for this purpose, but I'm a bit overwhelmed.  I'm thinking about installing 1" of sound insulation inside the "doghouse" enclosure for the engine.  Do I need a Mass barrior, foam, or both?  What will give me the quietest boat I can get?

Usually a combination of barrier (MLV) and absorber (foam) is needed.  The technique is simple: cover the engine room as much as possible.  Sometimes a layer of MLV outside, over the top is needed. (Or you can start there).

Our foam is closed cell so will not aborb moisture  or odor and is easily applied with contact cement.
