The Country Boy's Outboard
Welcome to the home of Swamp Runner™, the oldest, fastest, and most affordable mud motor design on the market.
We are SPS North America, Inc., and we can help you reach those choice hunting and fishing spots that are simply unreachable with a conventional outboard engine. Go where no outboard would even dare, and get there at a fraction of the cost, with the best value in a do-it-yourself longtail motor available in North America.
Our universal kits are designed to fit a variety of air-cooled horizontal-shaft engines sold by Briggs & Stratton, Harbor Freight Tools, Honda, Kohler, Lifan, and others.
Do-It-Yourself Country Boys love our longtail kit because it has several unique attributes, which no other mud motor manufacturer can claim;
- Our kit has been in production since 1957, making it the oldest continuously produced longtail design in the world, and the predecessor to all American mud motors in current production.
- Our kit is the only longtail design backed by over 50 years of field testing in the remote jungles of Southeast Asia. No American longtail manufacturer can say that!
- We guarantee that our kits are, by far, the best value of any mud motor kit on the market today. There is no mud motor anywhere that is more economical to own, operate, and maintain.
- We offer the versatility and freedom to choose your own engine.
- Our kit can be assembled, in less than an hour, using basic hand tools.
- EVERY part of our kit is replaceable, and available.
- Our parts cost a fraction of what others charge (Example: our propellers start at just $9.99).
- Our exclusive quick-disconnect coupler allows you to replace the entire shaft assembly in seconds. This is not possible with any other mud motor.
- Our engine frame brackets are constructed of thicker steel than used by most other mud motor manufacturers.
- We have the only ambidextrous tiller steering in the industry.
- We offer the only stainless shaft assembly (optional).
- The simple design of our kit has fewer parts than any other longtail drive system.
- Swamp Runner™ longtails are faster than the others.

With all of your tech support and being able to pick up the phone and talk to you directly is great and almost unheard of these days. I work for a large publicly traded custom manufacturing company and there number one focus after safety is customer care. Reason being without a customer you have nothing. It seems you guys have this figured out. Keep up the great customer service! Matt C., Hortonville, WI
I wanna thank you for all your help. Great customer service. Best I ever had. Polite and very professional. The shipping time is unbelievable. I ordered it Sunday and it'll be here Thursday. That means I'll be ready for fishing Saturday. Outstanding. Chad B., Corpus Christi, TX
This is the reason I decided to do business with you, and not those other guys, because of your prompt response. Richard H., Saint Paul, MN
