## Customer Reviews

### ⭐⭐⭐⭐⭐ Outboard Motor Soundproofing
*by D***D on August 11, 2025*

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.

### ⭐⭐⭐⭐⭐ Good product
*by D***R on April 20, 2025*

Works well in our 1967 Chevelle. Easy to install and helps to minimize the sound and reduce heat inside the car. Would buy again for future rebuilds.

### ⭐⭐⭐⭐⭐ Good quality
*by D***E on August 14, 2025*

Works well it's doing what it's supposed to do great investment
