Exclusive Features

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....

NOTE: All engines with gear reduction box options are not compatible with this kit.

CUSTOMER FEEDBACK:

"Just thought I'd let you know that we're up & running with the mud motor!  The kit went together very nicely.  The only thing so far that's stopped the boat is dry land.  Neighbours who've seen a boat going where no boat has been lately are impressed!"  - Rod C., Eustis, FL

"Rig was impressive today. 3 men (520 lbs) and fishing gear. Pushed through some shallow stuff."  - Glynn P., Guy, TX

"All of our boats have your mud motor kits and WE LOVE THEM!! Just wanted to drop a line and say thanks for making a quality product we enjoy using!"  -Kenny S., Largo, FL, & Cole J., New Smyrna, FL
