Performance Motors
Limited annual quantities.

When you own a Mud Buddy 35 Vanguard Sport you have 10 Levels of High Performance available to you.

If you want power, run large boats and loads, we have the Mud Buddy motor for you.

We now offer tuned exhaust and have contracted with a Briggs V-Twin high performance motor shop to build us quality larger horsepower motors.  These motors have a combination of carburators, cams, push rods, roller rockers and head work.  They run at higher rpms and pack a serious punch.

Motors vary in performance depending on the custom components added so we have distinquished them in levels.  Level 1 being the smallest horsepower, with level 6 our most powerful.

Warranty Notice:  These are custom built engines and do not have a Briggs and Stratton engine warranty.  The custom motors listed here have a one year frame warranty and a six month limited Mud Buddy engine warranty.


You can order these products from Mud Buddy or add performance later.  All 2007 Mud Buddy frames and drives are sold with the HD6000 frame components. So they are ready to add power when needed.
