I purchased 1 roll of Quiet Barrier™ Specialty Composite w/PSA for the inside of my boat engine cover. I didn't use a dB meter to measure the difference before and after, but I was happy with the results. There was a noticeable difference in the ease of conversation while the boat was underway towing wakeboarders. I have a direct drive engine and was able to cover 80% of the interior of the engine cover with 1 piece of this product. I could add a 2nd piece and improve the results, but I'm happy with what was achieved with 1 piece. I ended up prioritizing the portion of the engine cover facing the driver and passenger seat which left the 20% facing the rear passenger seats less protected. The other thing that people should be aware of is the added weight. This mat is heavy and does impact the effectiveness of the struts in holding the engine cover open. Upgrading the struts would help solidify the cover in the upright position, but the old ones were able to keep it open with the added weight. I was also satisfied with the adhesive backing of this product and believe it will hold everything in place without an issue.
