As a result, this will show the engine sizes the small kit was installed on, the kind of boat the mud motor was put on, along with the weight, speed, propeller, and RPMs reached.
Most people put the SPS Swamp Runner Small Kit (46lbs) with the 6.5hp Predator Engine (37.5lbs) - This setup will total just under 85lbs.
Small flat bottom jon boats seem to be the popular go to for this kit.
For example, User: JD reached 31-mph in a 10' jon boat with a modified 196cc Honda engine spinning 7500 RPMs with the 5.5" stock prop.
However, most customers use a stock 212cc predator and put it on a 1232 or 1236 jon boat and achieve a speed of around 12 to 14 mph with one to two people.
In addition, if you want a little more power, take a look at our SPS Medium Swamp Runner Kit (57lbs) which is normally paired with a 13hp Predator engine (73lbs) totaling just 130-lbs.

I wanted to thank you again. With the small kit, I own the Shenandoah river. Yea, people float some parts of it and when it’s high, you see a few jet boats where you don’t usually see them. Unless it’s super low I run almost all of it and some tributaries. Anyhow, the wife and I discovered this water fall in the side of a mountain that I don’t think a lot of people know about. I have had to straighten and repair the the hull a few times but the look on their faces when we plane by is priceless. Thanks for keeping the parts available.

I must say that I am completely satisfied with the mud motor kit I had purchased from you earlier this year! Your product has far exceeded my expectations. This motor has made it a breeze for me to access the backwoods lakes and ponds that I love to fish and hunt.

Summer is coming here in Ohio. I have one of your small kits and I love it. .276 lift cam, 27 lbs springs, chrome moly push rods, billet rockers, honda flat top piston, reamed alky carb, billet flywheel and rod (arc), stainless valves with billet retainers, 12 degree timing, milled head, one inch tuned kart header. It sounds great and runs smooth with your kit on it. I would like to also buy a bigger kit for a 16hp motor.

I was doubtful that this was a practical boat motor. But when my 40 year old 9.8 Mercury kicked the bucket I had to look into a replacement. My choices were small. Replace it with a new motor for $2100 dollars, or get another old motor and throwing a ton money in it every year to keep it going, and with parts starting to be hard to find. One of my coworkers offered to let me try his Swamp Runner mud motor. I gave it a try and WOW it really worked well with my 14′ jonboat … I was so impressed with the simplicity of the setup. You sell a great product and I can’t wait to get it in. To think what I have in it is about the same amount of cash I would have payed for a used motor saving me $1500 or so dollars. Thanks

You guys put out one heck of a product! I love my Swamp Runner!

I just wanted to say thanks for selling a great product at a fair price. I have really enjoyed my Swamp Runner longtail. I got the kit for the 6.5 Predator and I’m running it on a 12 ft Sea Nymph boat. I have put it to the test while smallmouth fishing in the rocky hydrilla filled waters of the Staunton River here in VA. I have been able to access all kind of spots that were only accessible before with long trips by kayak. I have a bunch of people interested in your product and I love all the looks and questions I get on the water. I always recommend yall and tell how the customer service is top notch.

My small Swamp Runner works great. I’m glad I went with SPS. I’ve been changing the minds of the serious “American mud motor” guys every time I launch. The benefit of the prop angle is evident right away. I passed a guy with a surface drive twice the size of the small kit. I also really appreciate how well the kit is made. I have taken it places most boats just can’t go, and I’ve put it through the paces scouting new duck spots. It has proven to be bullet proof. Sand, gravel, rocks, brush, clay bottom, silt, millfoil, coons tail, reed canary grass, bull rush, arrowhead, lily it just plain doesn’t matter the kit doesn’t break

Just received my small kit and assembled it using a Predator 212 with intake/exhaust/jet kit, and the thing is awesome. I’m plowing through matted hydrilla and getting to duck holes i couldn’t reach with an outboard. I look forward to seeing how far back in the wooly swamp i can get!

Hello! Just wanted to drop a note and say how very pleased I am with my Small motor kit I have purchased. The kit arrived very quickly and in excellent condition. I immediately began piecing it together. The instructions were very clear and I had it together in about 2hrs, even though I have very minimum mechanical skills. We just took the boat out yesterday to test the motor. Everything worked better than expected! With my wife and I…and our 3 children, the kit, using a Predator 212 engine, was pushing my 14ft semi v-hull an average of 11MPH upstream. The kit performed flawlessly! Thanks for a great product!

Damn boys, you weren’t joking about heavy duty parts! I got my kit today after ordering three days ago. Very, very, happy. The pictures on you site don’t do justice to how well they are made and how heavy duty they are. Can’t wait to get this on the back of my canoe. Thank you.

I just bought a Small kit with a Predator 212 motor, running on a very light weight 12 ft Jon boat. It’s perfect for what I need. I was very surprised by the speed of this thing. It’s faster than a 6hp outboard I had on the boat.”

Used your small kit picking up people that were flooded in by hurricane Harvey. We cut across shallow areas and sidewalks where others could not, went over the top of submerged cars that outboards were getting hung up on and destroying props, saw rescue teams in zodiacs with their outboards getting hung up in bushes and fences. After using mine for 48 hours without one issue getting people out of attics and off rooftops I think every urban rescue team should have your kits at their disposal.

After a little over a year of using mine on a 7hp, I have, and would recommend these to all duck hunters. I tried going to a spot I normally hunted last season with a conventional 9.9 and spent more time dealing with weeds and the shallow bottom, than I did dealing with my duck blind. A Swamp Runner is a must have for avid duck hunters.

I purchased a small kit with the stainless shaft about a year and a half ago and love it! I run fresh, brackish and some salt water. Have it on a 15′ Discovery Sport and that thing has gotten me through the most weed choked shallow portions of river I can imagine. Additionally I’ve been able to drive my canoe over fallen trees, trash and whatever else is in the way. Honestly the only thing that slows me down is answering peoples questions about my motor setup.
David C (verified owner) –
I am very happy with my purchase! Wish I would have purchased one of these years ago. Best season in 15 years, and the Swamp Runner had a lot to do with our success

Out using the Swamp Runner on the Colorado River in La Grange, TX! Owned y’alls kit for two years now and loving it
Gene K. (verified owner) –
I honestly can’t say enough good things about the SPS/Swamp Runner kit. I bought a small kit to use with a Predator 212 and the rest is history. I beat mine like a rented mule and it has yet to let me down. The only issues I’ve ever had were motor related and had noting to do with the products Swamp Runner sells. I highly recommend buying a variety of propellers in different sizes or at the least one spare for the boat, thank me later.

I ordered the small Swamp Runner Kit and Salt Water shaft on a Tuesday and was delivered that Friday. The digital installation guide is very helpful. This and the Youtube videos made by the community, I was able to get on the water the following weekend with no issues. Can’t wait to try it out in the marsh! Highly recommended even if you have limited mechanical skills.
