Mini SwampRunner®

Swamp Runner Mini Kit

View Customer Performance Stastistics

Engines 2.5 to 3 HP


We recommend our MINI SWAMP RUNNER® mud motor kits for small skiffs, layout boats, flat-back canoes, kayaks, pirogues, and sneak boxes.  Recommended transom height 12" or less for optimum shaft angle.

If you need a super light weight mud motor that you can easily carry, but with loads more torque than those "weedeater" longtails, this is it.  The fully assembled MINI SWAMP RUNNER™ weighs right at 50 lbs dry weight!

Our MINI kit ships with 5” & 5.50" diameter propellers, generally used with engines between 2.5HP and 3HP.
Kit Weight: 30 lbs.

"Finally, I can afford to go boating again.  Laissez le bon temp rouler!" – Max F., Houma, LA

"I would like to start by saying the mini Swamp Runner kit has been great.  Here is a video you might be interested in using since it shows, what I consider, the locations where this longtail truly shines.  I don’t care what any “expert” says. My use would slaughter even the strongest outboard style mud motor and leave the American longtails impractically heavy.  Many thanks"  - Colby M., Dripping Springs, TX

"I just thought I'd drop a line to say thank you again. My mini kit has preformed  flawlessly time and time again. Still using it in the Virginia creeks to get into the real skinny water. I keep it greased up and keep spare props ( haven't had to replace one yet ) aaaaand it just keeps pushing. I'll be a customer for as long as you guys are around." - Matthew K., Quantico, VA
