I have the 200hp Volvo and when I go above 7kts., it is so loud we have to shout when talking and even shouting does not work most times. any one else have this problem? How can it be solved or made more tolerable?
Thanks

Is your engine compartment insulated? Sea Otter has acoustic insulation panels along the starboard and port sides of the engine compartment and a thick noise suppressing layer of foam across the underside of the floor boards. See the offerings at... www.soundown.com/index_Marine.htm.

Good luck...

There is no room for a thick layer of anything! There is no insullation on either side except for a few small pieces glues to the side of the tanks. Will check soundown. Thanks

L. L. Bean sells heavy duty all weather mats ( water hog?) that makes it safe
For the dog to jump around in the cabin. Mat also keeps humans from slipping
On the varnish after a swim. O yea, mat helps with engine noise. Larry

I know the engine compartment is tight. Sea Otter has a Volvo 200hp TAMD41A engine. There are noise battens along the sides of the compartment between the engine and the two sets of fuel tanks and fresh water tanks on either side noise battens under the floor boards, above the engine. The noise at 13 knots is bearable.

Send me an e-mail address and I'll send you some pix.

Just bought and cut to fit, 2lb premium carpet underlayment, from Soundown in Salem, ma. Placed it over the floorboards in main cabin. What a difference in the noise level!! Now I will just buy some carpet to cover it up (it's black) and good to go...quietly. Extremely impressed! Bought a decibel meter and prior to this underlayment, the reading was 90!!

Diannedri - do you have a decibel reading after the carpet was installed? You mentioned it was 90 before. I'm looking into options as well - maybe just carpet or maybe both carpet and acoustical barrier in the engine compartment. Thanks!

Does anyone know anywhere I can buy the Soundown underlay? I have contacted Sundown (twice) by phone and e-mail but still with no response.
I did notice this product from Cyber Bridge Marine. Is this the Sundown product? Sure looks like it.

Thanks.
