Express® Mach4™ - Left Hand - Stainless Steel Propeller - EX-1421-4L - 4-Blade - 14" x 21 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.

Good looking shelves
Size: 11.6"D x 15.7"W, Color: Black, Size: 11.6"D x 15.7"W, Color: Black
These shelves turned out perfect for my bedroom project! I read lots of reviews about people having trouble with the wall anchors not holding up, but I’m going to equate that to user error. I had no trouble installing these and even took a couple shortcuts. I only used two wall anchors per shelf, but also pre checked the holes for studs. I used one dry wall screw per shelf as well. Knowing how wall anchors can be, I used one drill bit size smaller than the directions suggested. They said use 1/4, but I used 15/64. Probably could have gotten away with one smaller than that at 7/32. With all screws, I made sure not to press too hard into the wall and just turn the screw. That helps the anchors and threads stay snug in the dry wall. There was only one shelf that came out feeling a little saggy, but I think it’s because the holes in the shelf are not quite right. However, it still holds strong and no problem with a box of shoes on it. All this being said, I pre weighed my shoe boxes and knew I only needed to hold about 5-7 lbs. I was super detailed with measuring the bracket spots to make sure everything was spaced and leveled appropriately. The wood on the shelves does feel a little cheap, but it looks great so I couldn’t care less. I would purchase these shelves again and might have to as my display collection continues to grow.

I put these shelves in a strange little cubby that was created in my kitchen by removing the sad excuse for a pantry that was once there. Super easy to hang, I’ve only hung two here and have other plans for the 3rd one. Good purchase for sure. Very sturdy and look expensive, without the high cost.

These were perfect for what I needed & easy to install with included hardware; looks great and looks like quality item. I like that they will hold 20 lbs so I can change what I place on them with no worries.

Sleek and attractive
Size: 12"D x 23.6"W, Color: Black, Size: 12"D x 23.6"W, Color: Black
While these didn't come in the color I was looking for, the size and price point were just what I was looking for. Installing them didn't take too long and was simple enough, but the end result did seem a little more wobbly than expected. I used them to display mine and my boyfriend's boots, and they held up fine, but I think 22 lbs per shelf would be pushing it. I was able to easily cover the shelves with wood grain look contact paper and easily trim the excess off with an Exacto knife to get the look I wanted. I'm happy with how it turned out.
