There are two other US based resellers of inferior Thai longtail brands who have made attempts at copying features first introduced by Swamp Runner, The following is a short list of differences you will NOT get from one, or the other, or both of these other two brands being offered;
♦ LIFETIME WARRANTY on coupler shafts and housings! That's right. Swamp Runner offers the best warranty in the industry, and is the FIRST & ONLY mud motor company to offer a lifetime warranty on key drivetrain parts. All Swamp Runner couplers are manufactured from heavy duty steel that will last a lifetime, which is why they come with a LIFETIME WARRANTY. We DO NOT utilize aluminum couplers, which will corrode from electrolysis and can eventually crack.
♦ SPS couplers and tiller handles are hot-dipped in galvanize, followed by an additional coating of paint. This double coating offers far superior corrosion resistance and paintability over the chrome offered by others.
♦ The coupler shaft of this kit rides smoothly on a high quality sealed Japanese radial bearing, while economy Thai long tails have no bearing or utilize a cheap unsealed Chinese bearing.
♦ We offer tiller handle mounts for left or right hand steering. Most other Thai longtails have right handed steering only.
♦ Our transom bracket is far deeper, wider, and heavier built, offering a safe 2" bite on the transom. Other Thai longtails have only a 3/4" bite, and/or are made from thinner stamped steel.
♦ SPS transom bolts have transom pads, providing a larger surface area to grip the transom firmly without digging into the transom and damaging it.
♦ The winged heads of SPS transom and coupler bolts are constructed of heavy duty steel, while economy Thai longtails use cast aluminum winged bolts that can break.
♦ The diameter of our tiller handles will accept custom throttle levers, while other Thai longtails have a diameter that will not allow it.
♦ Swamp Runner longtails have grease zerk fittings located in numerous locations to make lubrication easy.
♦ The engine base of our Small, Medium, and Large kits can be moved forward and backward for balance adjustment.
♦ The gimble bracket of this Swamp Runner kit pivots smoothly on sealed roller bearings, while the economy Thai longtail brands use dry bushings cut from conduit pipe.
♦ All our kits come with a high quality tethered kill switch. We don't use the cheap switches that will deform and fail after a little sunlight.
♦ The rails of the engine mounting base and transom gimble brackets on this kit are .48" thick, and constructed of JIS SS400 grade structural steel (equivalent to AISI-1018 or ASTM-A36.
♦ SPS utilizes refined manufacturing techniques that are a trade secret, to produce a highly balanced shaft assembly you just can't get anywhere else.
And there are other differences we don't talk about....

"Hope all is well with you. 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." - Wes R., Front Royal, VA
"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." – Anthony D., Cambridge, Ontario
"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." – Don S., Martin, OH
"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 inpressed with the simplicity of the setup. You sell a great product and I can't wait to get it in. Motor is built, just waiting on delivery. 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 - Don S., Belleville, IL
"You guys put out one heck of a product! I love my Swamp Runner!" - Hunter A., Augusta, WI
"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." - Todd H., Long Island, VA
"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." - Elliot R., Menomonie, WI
"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." - Jacob B., Eastover, SC
"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." - Jonathan S., Apopka, FL
“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.” - Chris C., Kingston, Ontario
"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." - David C., Freeport, TX
"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!" Andrew G., Quinton, VA
"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." - John N., Sussex, NJ
