Small block Ford running hot? Flowkooler designed a high flow water pump with a CNC machined billet impeller, an increased vane count and a reduced casting-to-impeller vane clearance. It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids.
FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot Ford engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

Just right for protecting river trip guides
Size: Regular - 12 x 16 Inches
Nice and durable - heavy duty. Getting ziplock to close is a pain though - lick or spit helps.

Misleading size
Size: Regular - 12 x 16 Inches, Size: Regular - 12 x 16 Inches
The quoted size (12 x 16) includes the webbing and unusable area due to the sealant. The actual size of map that can be fit is a little under 10.5 x 14.5 inch. It's annoying that I can't get my Fisher maps (22 .5 x 28.5 inch) in on a single fold.

Fantastic Watch - Premium Look
Color: yelllow
I am definitely a watch person. I have probably 10-12 watches included a Movado, two Esquires, and multiple Stuhrlings. I like watches that look classy but are considered mid-line (or even upper low line) luxury. This watch has the look and display of a much more expensive Garmin. It has a very clean layout and super easy to read. I have been approached by people thinking I was wearing a Garmin watch and little did they know, it was a lowly $20 watch. Granted, you can feel its lower quality when you hold it in your hand. It is not as heavy and doesn't feel as durable. But it is $20 so what can you expect? I have not tested its waterproof abilities but I will say it works amazing for jogging and bicycling with. My yellow watch has stayed relatively clean and does not have any weird stains that you might normally think would occur on a low quality band such as sweat stains or dirt stains.
So far I am very happy and it is now almost a year later. The battery seems to be going strong and the display does not show any signs of fading. I like the color selection and the simplicity so much that I may buy a few more colors just so I can change it up periodically. But for now, I am sticking with just the one.
