Express® Mach4™ - Left Hand - Stainless Steel Propeller -
EX-1421-4L - 4-Blade - 14" 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 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.
