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

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.

Note: A Hub Kit is required for installation of this propeller. See the Turning Point Selection Chart or the Prop Wizard™ for hub kit selection.

Where do I start! This man is a genius, I may have ordered a amateurs dream from this man, went all out on garmin products from gpsmap screens to the live scope lv34 and to juice them up I went with all powerhouse batteries and charging units! Well now on the boat I’m staring at this out dated minnkota and it just looked out of place so I went ahead and ordered up the KRAKEN! I can’t stop bragging on how much you have helped me, even face timing me on the water to fine tune my Livescope, there is no big box store that could even come close to offer this level of customer service! You will forever be my go to company! Thank you again!

Very fast shipping. Very knowledgeable guy to deal with. I inquired after hours and Chad responded quickly and chatted with me for way longer than necessary because I knew nothing about livescope. Who offers there cell phone number to call with any install questions??? Chad does. I got a friend request from him and accepted. Felt like I bought from someone who values my purchase as well as my friendship. We may never meet but I feel like I have gained a great friend. Thanks Chad for all your time spent explaining what I wanted and giving me choices. This won't be my last purchase..

It has been a pleasure dealing with Chad at Chaddy Boys! I had contacted him many times on the phone and has been very helpful! I felt like we had been old friends for a long period of time! Chad sent me many quotes and was very helpful on choosing the electronics setup I was seeking! I ordered my unit and received it on exact date I was quoted! I will definitely be buying from Chaddy Boys again!

This 16 volt battery and Run and Gun Charger is the only way to outfit your boat. Fish all day with no worries. Chad is very knowledgeable and helpful with the everything you need for a great day on the water. Now just waiting for a 36 volt to have the perfect setup. Thanks Chad.
Update* Well we just installed the second battery and run and gun charger. Took out 3 lead acid and about 120 lbs. Looking forward to the new system. Gonna be awesome. Thanks again Chad

We offer on the water Face-Time calls for product install, setup & graph tuning for side-Imaging, down-imaging & livescope! I took this side scan image 4 years ago.
