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.

Turning Point manufactures Express propellers to fit 9.9(bigfoot)-300+hp Evinrude®, Force®, Honda®, Johnson®, Mariner®, Mercruiser®, Mercury®, Nissan®, OMC®, Parsun®, Suzuki®, Tohatsu®, Volvo® Penta®, and Yamaha® Outboards and Sterndrives. Choose one of our Lifetime Warranty MasterGuard Installation Kits to fit your engine, then choose the propeller that matches your boating requirements. There are 3 and 4 blade, left and right rotation prop models with a variety of diameter and pitch options available for almost all boat types.

A Must Have For Your Summer Beach Bag!!
Style: SPF 30, Size: 1 Fl Oz (Pack of 1)
I recently purchased the Sun Bum Original SPF 30 Sunscreen Face Stick, and I am thrilled with its performance. This sunscreen stick has become an essential part of my beach routine, and I couldn't be happier with the results. One of the standout features of this product is its convenience. The stick format makes it incredibly easy to apply the sunscreen evenly to my face. I love how smoothly it glides on, leaving no white residue or greasy feeling behind. It's compact and fits perfectly in my bag, so I can carry it with me wherever I go. The level of sun protection provided by this sunscreen is fantastic. With SPF 30, I feel confident that my skin is well shielded from harmful UV rays. Whether I'm spending a day at the beach or just running errands around town, I know that my face is protected from the sun's damaging effects. Another great aspect of this sunscreen is its formula. It's lightweight and non-greasy, which is perfect for my combination skin. Unlike some other sunscreens I've tried, this one doesn't clog my pores or cause breakouts. It feels comfortable on my skin throughout the day and doesn't interfere with my makeup application. The Sun Bum Original SPF 30 Sunscreen Face Stick also has a pleasant scent that reminds me of summer. It's not overpowering or artificial, which is a big plus for me. I appreciate the attention to detail in creating a sunscreen that not only performs well but also provides a pleasant user experience. Overall, I highly recommend the Sun Bum Original SPF 30 Sunscreen Face Stick to anyone in need of a reliable and convenient sunscreen for their face. It offers excellent sun protection, has a lightweight and non-greasy formula, and is incredibly easy to apply. With this product, I can enjoy my time in the sun without worrying about my skin's well-being.

Beach bag staple
Style: SPF 30, Size: 8 Fl Oz (Pack of 1)
I’ve used Sun Bum for years and always come back to it. SPF 30 is perfect for everyday beach and pool days, and it gives solid protection without feeling heavy. It goes on smooth, doesn’t feel greasy, and doesn’t leave me looking ghostly. The smell is classic Sun Bum summer vibes and not overpowering. I’ve worn this in full sun and never had issues with burning when I reapply. Easy to rub in and comfortable to wear all day. Would absolutely repurchase.

The smell of summer
Style: SPF 30, Size: 8 Fl Oz (Pack of 1)
Love this lotion and its smell! Offers both protection and hydration and is my go to sunscreen for tanning / laying around. It'd definitely not my sunscreen for running / workouts / etc. because it doesn't feel like it hold up great to sweat.
