Featured Build: 2001 Master Craft Pro Ski Boat
Mike's ski boat
This boat engine cover remodeling project was done by Mike and his son over the winter of 2016! Their goal was to remove the old factory insulation that was falling off and replace it with some new high-quality Amertican-made Second Skin sound and heat insulation. Check out these awesome before, during, and after pics submitted by Mike.
Mike's 2001 Master Craft Pro Ski Boat
Let the dirty work begin. Scrapping out the old failing factory insulation to get back down to a good base starting point is key to long-lasting replacement.
It never hurts to spray on some primer before starting fresh.
On goes the first layer of the Boat Engine Compartment Insulation Package, the Damplifier Pro.
Next up, is layer 2, the sound and heat insulation layer. Heat Wave Pro was used on this boat for the second layer. Make sure to tape up any seams or edges with high-temperature foil tape.
Mike and his son are all ready to hit the open water and enjoy their quiet and cool boat all summer long.

This project was a few years in the making. Scott covered the entire boat doghouse with Damplifier Pro and then applied the Heat Wave Pro on top with foil tape on the seams and edges. This reduce his noise transfer into the boat area by a a good 8 dB, keeping him quiet and cool while driving around the lakes.
After years of use, it was time to get the engine cover replaced. Second Skin to the rescue.
First layer of the boat engine compartment kit is the Damplifier Pro. Used to kill vibrations and reduce heat transfer. Rolled on with a wooden roller to formn a solid bond.
Follow that up with complete coverage of the Heat Wave Pro. Using the high temperature foil tape to seal the seams and edges.

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.
BEFORE - 02 mph - 61 db 05 mph 2300 RPM - 69 db 12 mph 4800 RPM - 83 db 20 mph 5300 RPM - 85 db 25 mph 5500 RPM - 93 db
AFTER - 02 mph - 59 db 05 mph 2300 RPM - 64 db 10 mph 4200 RPM - 78 db 20 mph 5100 RPM - 81 db 30 mph 5500 RPM - 83 db
Final look with the Second Skin Boat Kit along with the factory foam added back on.
From the Yamaha factory they only add a small square of foam, doing almost nothing.
Follow that up with complete coverage of the Heat Wave Pro. Using the high temperature foil tape to seal the seams and edges.
After some removaland clean up work, Adam applied the first layer of sound deadening to the boat engine cover.
Damplifier Pro added to the fuel tank cover.
Side walls covered with Damplifier Pro.

1988 Tiara 3300
Steve, all the way up in Canada used our premium boat engine cover insualtion kit to get his 1988 Tiara sounding quiet again after years of the factory insulation falling off.
Time to get this boat nice and quiet!
When you open up the hatch and see this...it's time for some new stuff!
Factory heat shield and noise insulation is failing and falling off. Time for an upgrade.
1st step, get the old stuff off and clean the surface well with denatured alcohol.
1st layer of Second Skin to go on the cover is the Damplifier Pro, to kill vibration noise and stop heat transfer.
2nd layer of the Boat Engine Cover Kit, Mega Block. To absorb the airborne noise and also to thermally insualte the engine cover. No more sound and heat coming up through here with the Second Skin treatment.
Boat Engine Compartment Insulation Kit . . . because we heard you loud and clear.
Your boat deserves the same love as these projects above. This kit has everything you'll need to quiet that engine so you can stop screaming, "I can't hear you." The reply is always inevitably, "What?" anyway. Skip the theatrics and treat you boat right. When you pull up to the dock and everyone notices just how quiet your boat is, you can relish in how simple it was to do and how good you looked doing it.
- Boat Doghouse Kit: Damplifier Pro stops vibrational noise from the fiberglass housing. Heat Wave Pro brings the insulation and sound absorption to the table. This kit was designed for anyone with a doghouse engine compartment on their boat that is looking for some noticeable noise reduction.
