Globe Marine's Run-dry Impeller 270Globe Marine is pleased to announce another new marine impeller model added to its line of world-class Globe Run-Dry® Impellers — the only impellers able to run dry for up to 15 minutes. This model is the fifth new impeller introduced into the market by Globe this year.

Globe Marine Run-Dry Impeller 270 pkg
Run-Dry® Impeller Model #270 (part number 01-12-2046) replaces Sherwood 27000K and Cummins 3974456 impellers and uses Globe’s proprietary long-lasting, self-lubricating, composite material. Unlike impellers made from traditional neoprene materials, Globe Marine’s Run-dry® Impeller is guaranteed to run-dry for up to 15 minutes. Those crucial minutes could mean the difference between either saving your engine or incurring costly repairs. And, this impeller comes with an O-ring to make replacement even easier.

Dr. Strange Composite?

(Or, How I Learned to Stop Worrying and Started Loving Non-Metallic Materials)

question mark icon Surfing around the internet this week, looking for what’s new in the marine and boating world, I came across quite a few forums where the questions arose:

  • What is a composite anyway?
  • Are composite impellers the same as plastic?

Much to my dismay, the forum posters almost invariably concluded that composite parts were pretty much the same as plastic — if not in composition, at least in performance. Oh no! I thought and tried to post to the forums myself, but alas they were not allowing anymore comments. Hence, this month’s blog is on why composite parts are so much better than plastic.

What is a composite material?

What exactly is a composite anyway? Here’s a simplified definition from

Beackers & Cylinders

“Composite materials … are formed by combining two or more materials in such a way that the constituents are still distinguishable and not fully blended…

This type of material takes advantage of the different strengths and abilities of its different elements.”

In other words, a composite is a blend or mixture of two or more materials, one of which may/may not be plastic, in order to improve the properties of all the materials in the composite. One material in the combo might be chosen for its ability to bend or stretch, while another might be chosen for its strength. Different materials — anything from wood, to metal, to glass, to plastic, to resins (both organic and man-made), etc. — can be chosen for their desired properties to create a composite material. It all depends on what you want the end result to be able to do.

Aren’t they the same as plastic?

Globe Run-dry Impellers (various)Composites are so much more than the plastic used in picnic ware, drinking glasses and cigarette lighters. Many composites may contain plastics, like thermoplastics, but are mixed with other materials to dramatically change their physical characteristics such as shear and tensile strength, stretch, flexibility, ability to retain their shape (like microfiber foam) — or other properties.

For instance, our Globe’s Run-Dry® Impellers aren’t “plastic.” They may look and feel like plastic, but have properties that plastic alone doesn’t possess. Due to the mixture of numerous compounds, our impellers are self-lubricating and, as a result, can ‘run-dry’ in an engine for up to 15 minutes.

Traditional plastic or rubber impellers can bend, snap, or even break into small pieces that get stuck in the engine. Likewise, metal impellers can bend or warp causing the engine to stall.

Here’s why composites rock:

superhero iconBecause of its very nature, a composite’s whole is greater than the sum of its parts. Composite materials are like getting the best of both worlds: the strength of one material with flexibility of another yet still retain the shape of a third. (Or, other properties such as coefficient of friction, ability to ward off infection, invisibility to radar … the list goes on and on.) They’re like cherry-picking all of the best superhero powers and putting them into one. What plastic can say that?

The Best Marine Impellers on the Market, Just Got 100% Better

We didn’t think it was possible, but Globe Marine just improved the best marine impellers on the market by 100%. How do you improve on the only impellers guaranteed to run dry for up to 15 minutes? Give ’em more, obviously!

So, how did Globe Marine do it? Image

Now, all of the best-selling Globe Marine Run-Dry® Composite Impellers come with O-rings and gaskets, right in the same package with the matching impeller — all for the one price.

This addition allows repair technicians and customers to easily replace impellers without the fear of damaging or losing original gaskets and O-rings, eliminating the time and hassle of finding and purchasing replacement gaskets or O-rings.

Thirty-five of Globe Marine’s most popular marine impellers are being upgraded with new packaging to include their matching O-rings and gaskets.  Shipped out to stores and dealerships Friday April 11, 2014, the arrival of these new products is as anticipated as summer vacation.

“We listened to our distributors, dealers, technicians and customers who told us that including gaskets and O-rings along with our world-class Run-Dry® impellers,“ said Carl W. Forsythe, President and CEO. “This clearly positions Globe Marine as a leading provider of replacement impellers,” he added.

“We are really excited about this long-anticipated change for Run-Dry® impellers,” said John Dillon, branch manager for Marysville Marine, a large Midwest-based distributor of marine products. “This will significantly streamline the selection, purchase and installation process for us and our customers. It is a win-win for all,” he added.
