Express® Mach4™ - Right Hand - Stainless Steel Propeller - EX1/EX2-1321-4 - 4-Blade - 13" 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 state-of-the-art Swept Cleaver design for 40-150hp applications. 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. These Turning Point props also produced up to 46% more reverse thrust than other comparable designs in recent tests.

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.

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.

Nice shirt!
Fit Type: Regular Fit, Color: White, Size: X-Large
I added one of these shirts to another order just to see if they were any good. I was pleasantly surprised by the quality. It fits perfectly and looks pretty nice for a low cost casual dress shirt. Materials seem decent quality. Comfortable, soft fabric. Didn’t shrink too much in the washer and dryer. We’ll see how it holds up long term but so far so good

My new favorite shirts!
Fit Type: Regular Fit, Color: Grey, Size: Large
These are my new favorite shirts! I just ordered a 3rd. i wish there were more colors. Yes, the cotton is heavy-weight and I like that. They are just a bit warmer than regular dress shirts. The fit is excellent. I'm 5'9", 200lbs and L fits perfectly. Enough room without being blousy. The sleeves are long enough (finally!). (Most other 16.5/32-33 shirts always have sleeves that are too short). The fit/finish and detail is surprisingly good. They don't really shrink after washing and come out very soft. Not wrinkle-free, but that's ok since it means that the 100% cotton hasn't been dosed with chemicals. I expect they will wear very well over time.

Quality shirt. Not too blousy.
I'm 5'11" and hover around 175-180 lbs. so I'm a pretty average guy. I've been thin my whole life but now I'm in my 40's so if I don't watch it, my stomach will get bigger. I bought this shirt in slim-fit first. It was perfect but since these shirts are 100% cotton, I was concerned that after a couple washings, it would be too small (especially in the stomach area). I returned the slim-fit and bought this regular-fit (medium). For this review, I thought it would be helpful to compare the Amazon Essentials shirt to The Gap's regular oxford shirt. I've always liked the fit of Gap oxford shirts. Upon inspection, the weight and feel of the Amazon oxford cloth is exactly the same at the Gap's. I laid one of my old Gap shirts on top of this Amazon Essentials oxford. You can see from the pictures that the torso cut is exactly the same (about 21 inches pit-to-pit seam). I like that. I'm not a fat guy and I don't want a blousy shirt. This is neither too blousy nor too slim. Just right. The sleeves are perhaps 1/2 inch longer than the Gap shirt. Perhaps one negative is the tail. The Amazon Essentials tail is 1.5-2" longer than the Gap shirt. This makes the Amazon Essentials shirt a touch long for wearing untucked in my opinion. However, if you do tuck, a longer shirt stays tucked-in. So it depends how you want to wear it. I have a lady who does alterations. She'll charge $10 to shorten the tail if I wanted that. If I do have the Amazon shirt altered, it would still be a bargain. These are good quality shirts with a nice cut to them. I won't hesitate to buy them again. Highly recommended.
