Performance Kits 
Carburetor and Tuned Exhaust
for Large and Small Block Vanguard Engines

Mud motors have come a long way the past ten years.  One of the most important improvements welcomed by hunters and fisherman was the introduction of the large block Vanguard 29, 31 and 35 horse engines three years ago. Today these amazingly dependable and strong engines dominate the backwater motor industry allowing customers to push larger boats and loads like never before.

This year Mud Buddy is proud to introduce a full line of after-market performance kits designed to enhance the power of Mud Buddy Vanguard motor models like the Sport, Hunter and HD Lite. 

If you like power - just bolt one of these kits on to your Mud Buddy and you will instantly feel more aggressive throttle response, better mid range and enhanced top end speeds.

Here are the results of adding a single carb kit.

Note:  Look at the average to get a conservative power gain reading,
even though the engine performed better at 4400 rpm.
