“I cut grass and mixed a few leaves with no problem. This motor has the power to get the job done. Only take a couple of pulls to start and it kicked butt. Not heavy either; therefore, you can pick it up easily if necessary. The throttle system actually works too unlike some motors I’ve purchased in the past. Ability to use ethanol 10% is a plus as well.” – by Mason from Baton Rouge, LA

“My original mower had multiple issues after several years of use. A choice between a new mower or an engine was easy to make, especially with a 20% off discount. Filled with oil and gas and the engine started on the third pull. Runs smoothly and I did not notice any motor stutter as I plowed through some deep grass that would have been a struggle with the old motor.” – by LRoy the Tool Collector from Torrance

“This well-designed, well-built engine was a direct replacement to the Tecumseh on my Yard Machine mower. (5 minute INSTALL)! The cables took less than a minute to connect, Snap! This upgrade saved me $200.00 towards a new mower that I instead applied to hobby money…” – by Bladerunner from Washington

Ride Like the Wind with Predator Gas Engines

Get your motor runnin’ and head out on the highway!  Or the back yard, or lake, or wherever your powerful Harbor Freight Gas Engine takes you!  If you’re lookin’ for adventure, or maybe a reliable replacement motor, you’ve come to the right place.  With various displacements and many sizes available, we have an appropriate engine suited to fit your needs.  And, like a true nature’s child, we offer clean burning options to fit those tough California emissions laws.

It would take up a lot of space and time to go through all of our awesome Predator engines, so for now, we’ll just look at the range in sizes and power, starting with our smallest engine.  The 79cc gas engine is the ideal replacement engine for 3 HP motors.  What might you use this engine for?  Tons!


“This little motor was a direct replacement for my old 2hp Briggs on my edger. True, the motor is no quieter or smoother running but, it starts very easy and makes good power. For the money, I give the little motor a 5 star rating…” – Jim in Sidell, LA

“I put one of these 79cc engines in a small mini bike-it will pull my 235 lb. frame along at over 30 mph!!!! When you first pull away, you will notice a definite vibration, but it goes away quickly and the little engine really pulls!!!!” – T-Bucket Timmy from Allison Park, PA

If you think that little engine pulls its weight, just wait til you see the 420cc motor!  This one, just like all the Predator engines, is both durable and easy-to-use with a variety of items from lawn mowers to log-splitters.


“Used this to replace the blown engine in my OLD (1972) garden tractor. Works great. First real test was a blizzard (3 feet of snow fell, drifts over 5 feet in my driveway). Ran it for eight hours straight with no problems at all. Has at least as much torque as the 15hp engine it replaced.” – Gearheadengineering from Central CT

Whether you’re looking to replace a big engine or a small engine, or just looking for a new and reliable engine, the Predator gas engines are built for performance and longevity.  Just like Steppenwolf.  …?  Steppenwolf… Magic Carpet Ride?  No?  Born to Be Wild?  Okay, fine, the Predator engines are built to outlast and outperform Steppenwolf.  But, I say check out both and decide for yourself!

The Little Engine That Definitely Can

After taking your gas-powered equipment to hell and back year after year, the engine’s eventually going to conk out. And when that day inevitably comes, it doesn’t make sense to buy a whole new set-up, not when the only thing broken is the engine. Sure, you could get it repaired or try to fix it yourself, but that’s a crap shoot at best. For the price, you should just replace the engine.

The Predator 212 cc, 7 HP OHV Horizontal Gas Engine is fierce on power and performance, but really easy on price. That said, it’s also gained a large following with those looking to replace the engines on their wood splitters, lawn mowers, roto-tillers, pumps, compressors, snow blowers, lawn vacuums, leaf vacuums, generators… you name it. I even saw one guy who put it on his wakeskate winch.

The Predator engine is also the “green” choice with its super-efficient, clean overhead shaft design, which passes Carb and EPA standards in all states (there’s also a California-approved model!),and delivers a cooler performance and longer life. In short, the horizontal shaft makes this an ideal all-purpose replacement engine.

And now, during December 2012, Harbor Freight Tools is offering the hot Predator 212 cc, 7 HP engine for only $99.99 with coupon! Check out the store’s homepage to find this great deal.
