Review: Outboard Motor Soundproofing - Used this to quiet an old outboard motor that was too loud due to the original soundproofing being pretty much gone after many years (even the dealer can't figure out the year of this old motor). Worked great. I haven't measured the exact drop in the decible level, but it's noticeable. Easy to install with the self adhesive backing. Made a template using a paper bag, though I think cardboard would have been easier. Got it close, then dialed in the fit with a pair of utility scissors, laid it out and cut the soundproofing using the template. Double checked the fit before peeling off the adhesive cover and installing.
Review: Seems to work very well. Used on VW engine cover. - The original foam noise insulation mat on my 13 VW Touareg engine cover had turned dry and crumbly after almost 11 years. Several chunks were falling and tearing off. I wanted a new one. But they are NOT sold by Volkswagen, only the entire engine cover $$$. This sound mat works great. It was not hard to work with. I cleaned the engine cover, measuring the old foam insulator first and making a cardboard template. Then with a scraper and acetone, I removed the old insulation foam, and followed up with sandpaper and acetone. I cut the new insulation with a utility knife on a breadboard, and did small trim with industrial scissors. In about an hour, I had a new foam insulator, and it works. Engine noise is a little bit better than before, and it has held up to engine heat.

### ⭐⭐⭐⭐⭐ Great for engine cover
*by 6***T on May 5, 2025*

Rodents had started tearing apart the engine cover insulation and using it for nesting (Mazda 3). This provides good insulation that looks and works great, stays in place and doesn't provide nesting material. Would work for insulation attached to the hood as well.
