Express® Mach4™ - Left Hand - Stainless Steel Propeller - EX-1515-4L - 4-Blade - 15" x 15 Pitch

The Prop that put the "four" in Perfourmance! Turning Point's Four Blade revolutionized the propeller market when it was introduced. No one had ever produced a propeller with two different blade shapes (they call it Dual Geometry) for 90-300+hp applications. This prop is uniquely engineered with two blade geometries: (diagram label 2)two blades utilize the Hustler high performance variable rake and aggressive pitch design for incredible hole shot and cornering, and (diagram label 1) two blades utilize an offshore style design for high speed and maximum stern lift.

These props re-wrote the rules, proving that you can run a four blade that has unprecedented hole shot, handling, and rough water stability without the top-end speed loss you experience with other manufacturers’ propellers.

Now manufactured in our Industry leading TP17 stainless, the Express Mach4 series is perfect for any application that demands enhanced acceleration, cornering, and load carrying capabilities. This prop series is ideally suited for watersports, sterndrive boats, tri-toons, bay boats, and any vessel that can use stern lift. It is our best upgrade of older stainless designs from the 70’s, 80’s, 90’s, and ’00’s, and will outrun most newer props, including five blade ski props.

Proprietary Stainless Steel, TP17™

Formulated to meet the exacting requirements of the New Express Mach3 and Mach4 designs. 20% higher chromium content than the competition - more shine, better corrosion resistance. Almost 250% Stronger and 5X more durable than run-of-the-mill stainless steel. This new material allows Turning Point's Engineers and Designers the freedom to produce radical new designs that will help you wring the most performance out of your boat.

Large Free Flowing Exhaust Ports

Turning Point's Propeller Housings have massive Exhaust flow pathways. Their Propellers have 40% more exhaust flow Area versus competitive product. More exhaust flow and less backpressure can generate more horsepower. Like headers for your boat.

Lower Quality than Competitors
Color: Black, Size: 8' Wide x 30" Tall
Construction is different from the Wall I brought from Children's Factory. Would recommend going there for a higher quality product and to save some money.

Well made… for children?
Color: Black, Size: 8' Wide x 30" Tall
This review is for the 30” tall one. I’m honestly struggling to find a great use case for how short this is. I don’t have children or am associated with any institution where they may be some. I could see it being used for creating that type of sound barrier. The panel itself is very well made. Looks and feels like an air wall that you’d see in a convention center. I can absolutely tell there’s an acoustic absorption property to it. The whole thing unrolls quickly and is fast to deploy. As far as privacy goes, it’s kind of useless unless you are trying to wall in small children. I can’t really say the value is all here for this. Seems quite a bit more expensive than it’s worth.

Very pleased
Color: Black, Size: 8' Wide x 30" Tall
This works great, and I find it to be very effective at soundproofing. The hinge is good quality, and it rolls up easily. It is slightly on the heavier side, but that is to be expected considering its larger size. The materials used to make it are top quality, and it will last a long time.

Trying to limit the sound from the basement.
I still am in process of evaluating the function of these but from an early assessment they do seem to help take the noise down a peg. I have installed these between the joists in my basement so that as my kids get ramped up playing video games it could possibly help prevent the sound from rattling the house. I did not need to use the sticky side for this as I was able to slide them in place around other things to hold them still. With four panels I have ok coverage of the area and if they continue to prove effective I will get more to fill out the area even more. They appear well made and of good size but I am not an expert in sound absorbing materials. Still so far so good.
