My 1986 acoustic foam is in pretty bad shape and disintegrating. I was wondering if anyone had used this product from iBoat for their engine cowling?

I also saw this product but at 1 lb /sqf it seems like a different material that what was installed originally:

Also, looks like 1/2 inch thickness should be what I need but hard to tell how thick the original one really was as it is in such poor shape.


Thanks

original foam was about 1/2 inch thick. I pick up yoga mats at yard sales for a couple of bucks and use them. They accept contact cement very well and do not absorb gas and oil. PLUS--it is cheap and I am tight. However, they are a little heavier.

Wow, that's an awesome idea!!! Thank you Frank. What would you say is the noise reduction compare to the acoustic foam?

Well, I couldn't tell you The only real way to measure noise is with a meter. Outboards are so noisy that it would take multiple decibel reductions to notice a difference by ear. It does reduce the high frequency buzz of the reeds a bit though. Remember: Whatever you use, the air intakes still remain open and a source of sound.

Frank,
Thanks again for this tip. I just finished redoing the inside of the cowling using a Yoga mat ($10), works great and very easy.
No more old desintegrating foam all over anymore!!

Let us know if you are satisfied with the sound while running. Thanks.

Sounds the same as with the original foam. It's clean, light and super easy to install. All good!!
Thanks again for the tip.
