Sound proofing an outboard boat motor.
« on: March 29, 2007, 03:55:50 AM »
I am looking to soundproof my outboard motor.  Right now when the motor is wide open throttle it is almost impossible to talk to other passengers.  The engine cover is made of plastic and I only see a slight difference in the sound of the engine when the cover is on and when it is off.  I am thinking of lining the engine cover with some sort of sound proofing foam.  What would be the best choice of foam for this aplication.

Use the thickest foam you can get in there, see:

Another box cover might be needed...  Line it with barrier- MLV.

The closed cell vinyl nitrile foam can be in a continuous operating temperature of 180 to 220 degrees.  MLV has the same range (can go up to 250 degrees).
