The Express Mach3 OS Series of Stainless Steel Propellers are the next step in the evolution of our very popular larger diameter VO series. Our Engineers and Propeller Experts made improvements to the cup, leading and trailing edges, and the aggressive progressive rake and blade geometry that are Turning Point hallmarks. These modifications have produced a propeller with excellent hole shot, impressive bow lift, and class leading cornering. 

The Express Mach3 OS is perfectly matched to large horsepower bay boats, offshore center consoles, and high horsepower pontoons/tri-toons. It will fit all 90hp and  larger 4.75" gearcase outboards from all engine manufacturers, and Mercury® Alpha One™ and Bravo One™, and Volvo® Penta® SX sterndrives. Large diameter three blade propellers offer great mid-range fuel economy in many applications. Whether you are looking to maximize your time on the water, extend your cruise range, or just stretch your fuel dollars, the Express Mach3 OS is a great choice to get the most out of your boat.

Good value for my application
Style: 37.1 sqft(34 pcs), Material Type: Aluminum 197 mil
I wanted this product for heat and sound installation. Worked well for my application of insulating Jeep floorboards. Easy to work with. Good adhesion. I may have went for a little thicker material. But it's better than only carpet. That's what Jeeps have so it worked great for me. Good value for the money, I like the size of the squares since I needed to do a lot of trimming anyway.

Good value
Style: 16.3 sqft(15 pcs), Material Type: Aluminum 197 mil
Works well in installation but recommend an aluminum foil tape to go over all seams. Seems to work well as a heat insulator. Not sure about durability UNTILL we get some years under our belts.

Absolutely zero difference. Anyways, I have both doors full of the stuff. I'd pass if I were you.
Style: 8.7 sqft(8 pcs), Material Type: Aluminum 197 mil
Not what I was thinking. I've used insulation like this that was composed of heavy material, this one is not. This product must be for boats or airplanes where weight is a primary consideration and noise is not a problem. This is too light to have an effect on vibration or road noise. Absolutely zero difference. Anyways, I have both front doors full of the stuff and I'd pass if I were you.

Great in my trunk

Was almost enough to do my full trunk on my 2012 civic si. I have exhaust and a subwoofer that were making a lot of rattles and drones in the trunk. Took everything out and covered about 70% of everything including the wheel wells and the rear deck support, even put some under my spoiler and behind my license plate. Now, quieter ride and no vibration from the trunk inside OR outside the car even with bass cranked up. This is a great product and I would definitely recommend.

Does the job well
Style: 37.1 sqft(34 pcs), Material Type: Aluminum 197 mil
Really nice quality. There are strings woven into the top along the foil. Easy to work with. The backing peels off smooth and usually in one piece. Great value
