Just a heads up, you need to get the foam squares wet and sit them in the sun to expand them after you pull them out of compressed packaging.
I just used a spray bottle. Took about 30 min for the most compressed ones to expand.

It works. Really happy with noise reduction.
May need to improve adhesion over winter

Some additional observations.
The main noise improvements I noticed.
1) could barely hear the starter when firing it up
2) the raptors have a pronounced valve train noise that was now barely audible.
3) can’t hear transmission anymore.
4) the tones you can hear are lower pitched.
I didn’t tell the wife I added this material, her comment was simply, the boat sounds different.
Success.
