No brand name on it, but it hase a set of shiny felxible wings riveted to a stiff center. All stainless steel. Very strongly built, compared to many other flex fans I've seen. The center is blue, wings are bare metal.

I did a search on eBay for 'flex fan' and looked for anything in the 13"-14" size in good condition, good seller feedback, etc.

It took me about a month to locate one, under $20 shipping included.

I hunted through as many auto parts websites as I could find, but no one seems to sell fans this small. Which is odd, considering how many small engines there are these days!

I'd have liked to installed an electrical fan but the stock water pump hub is too close to the radiator in the back side, and the hood spring is too close to the radistor on the front side. With a little work I could have moved the radiator back about an inch, so I could have used an electrical fan.

This flex fan was easy, quick, cheap and effective.

Compared to the stock fan (sorry, I should have taken pictures before I installed it!) the wings are pitched more, and are larger, besides having two more blades.

Putting my hand behind the stock fan with the engine at idle, I could barely feel any air movement. This fan really moves some air! I plan to add a fan shround to increase its effectiveness. All I need for that it to find the proper material (stainless steel or aluminum sheet, 12 gauge or better).
