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.

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.

Decent Accessory Kit
Size: Eufy E25 Omni / E28 Omni E28, Size: Eufy E25 Omni / E28 Omni E28
This is a decent accessory kit I got for my E28! This kit comes with so many of the parts I needed to keep my E28 up and cleaning well. The accessories each fit my bot very well - the roller brush slid on with no issue and it didnt bind in any way. The knap on the brush is decent (a bit knappier than the OEM). This is nice because I have textured tile so a better knap will help clean inside the nooks and crannies. The kit comes with a lot of the needed items for the bot. One negative (but I didnt take away a star because this can happen in others as well) was that the cardboard on the dust bag didnt have enough glue to keep the bag on the stock board - it tore away super easily which was a bummer to lose a whole bag. Not the end of the world, but be carful inserting the bag properly to avoid tearing it away/open. All in all this is a decent kit and is a fraction of the price of others. Additionally, it is one of the least expensive kits on Amazon, which is nice - because we all could stand to save a buck or two.

Eufy Replacement Parts
Size: Eufy E25 Omni / E28 Omni E28, Size: Eufy E25 Omni / E28 Omni E28
The 14-piece replacement parts for the Eufy E25 Omni made a huge difference. It came with a roller mop, roller bushes, air filters, and dust bags. I hadn’t replaced any of my parts for quite a while and the vacuum was starting to not work very well. I ordered this set hoping for the best and was really impressed by the quality of the parts. Everything worked beautifully and installation was a breeze. After just a few seconds I replaced everything that needed to be changed and was scheduling for a cleaning. The new parts made a big difference in how well the vacuum performed and I couldn’t believe how much cleaner the floor was. I am totally happy with my order and will continue to use these parts.

Don’t buy
Size: Eufy E25 Omni / E28 Omni E28
Black roller brush doesn’t fit. Quality is not the same as eufy. The filter doesn’t have as many pleats ergo doesn’t filter as well.
