Express® Mach3™ OS™ - Left Hand - Stainless Steel Propeller - OS-1621-L - 3-Blade - 15.6" x 21 Pitch

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.

NOT SLIM FIT.
Size: Large, Color: White
NOT A SLIM FIT. Misleading. White is off-white, cream. Not neutral, bright white. Decent material. Ok quality. Textured, thin but not too thin. Dressy, not very casual.

Comfortable & Dad-Bod Approved!
Size: X-Large, Color: White, Size: X-Large, Color: White
I purchased this shirt in advance of our 10th Anniversary Cruise, and I'll say it was a success! I had never worn a shirt like this before, but I am now a fan. Cool, breathable, comfortable, and my wife loved it! Definitely Dad-Bod Approved. Quality was nice and I think was priced fairly well (might have bought on a sale). The size was perfect. I'm 6'2", 275lbs in these photos, and the XL was a great fit.

Not bad so far
Size: Small, Color: Light Yellow
mixed feelings about the quality... only worn/washed once and there are some dangling threads which I had to cut off which might lead to further degradation of longevity etc. The fit is a bit snug between S and M, I chose small regarding the closest fit to my chest size but it's ok. The fabric is thin so if you are a guy that doesn't mind showing off your form and fitness this shirt is flattering. The fabric is texture, light and thin so there is comfort regarding the lightness of wearing it. One could go a size larger for looser fit and more comfort but I actually like the tighter fit.

Perfect summer shirt...
Size: 3X-Large, Color: White
I am one that ALWAYS look at the 1 star reviews first. When I brought this shirt I did not... I brought 4 more in different colors. I have now looked at the 1 star reviews and I have to disagree.. Most say they are too thin. When it's 90 - 100 degrees outside this shirt is PERFECT.. It is airy and relaxing. I found it to be also perfect in size. I came back to order more but they don't have a few colors I am looking for. This worked for me all the way around..
