Boat Soundproofing

Wesley's Boat Engine Hatch

This project utilized the Damplifier Pro + Heat Wave Pro in the 36 sqft kit. Started by cleaning off all the old failing factory foam. Then applied the Damplifier Pro with the roller. Next he sprayed on the Spray Adhesive to the Heat Wave Pro and the top of the Damplifier Pro to adhere the Heat Wave Pro. Finally, tape up the seams and edges with the foil tape. Boat is now quieter and cooler. Second Skin Skin knows how to insulate a boat engine.

Yamaha Jet Boat Soundproofing

2020 Yamaha Jet Boat

Adam covered the engine door with the Second Skin Dampener, then the Heat Wave Pro, then put the original foam back in (cause why not). Everywhere else inside the engine bay he used the Damplifier Pro. Adam also covered the fuel compartment door with the Damplifier Pro which was 9 sqft. It's much quieter than before at idle/sunset cruise speeds making it easier to talk. And quieter when accelerating and at plane speeds. So all around it was worth the investment. Adam really liked that Second Skin is a reputable commercial brand, is rated to hold up to high temps, made in America, will act as a fire retardant, AND the great customer service. dB changes below.
