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. Turning Point's Props Run Faster, Pull Harder, and Handle Better.

Good for the price but will not repurchase
Size: 9, Color: Grey
My husband loved these at first. Pros -easy to get on/off -stylish -comfortable -interior/exterior sole construction lasted longer than other more expensive shoes -price is great Cons -after less than a year the mouth of the shoe widened to a point where they slide off way too easy rendering them almost unwearable. -laces cannot be tightened

Great watch - looks good and keeps good time
I love this thing. Good for a big wrist. Lume holds well and the blue lume looks awesome with the white/blue theme. Holds writhing a couple seconds (2-5) per day, which is pretty excellent at this price point. Would recommend.
