Additional Parts

The 16-hp motor by Vanguard can be used to repower many things from mud motors, grinders, drift bikes, water pumps, mowers, and go-karts.
With this 16 HP motor, we offer a couple of options that you can add via the checkboxes above:

  • High mount muffler with a starter side exhaust outlet (part #690906) +$145
  • 90-degree exhaust elbow if you wanted to point the exhaust gasses a certain direction (part #495518) +$16
  • Wire muffler guard & heat shield to help prevent things from touching the muffler while also re-directing heat away from the gas tank (part #691571) +$65
  • Oil filter adapter that relocates the oil filter. This is needed when purchasing an engine for use with one of our Swamp Runner Kits (part #808033) +$63

We used all these add-on options when we did our river trip on the Yukon River from source to sea. These options are pictured on this 16hp engine in our shop. Paired with our Medium Swamp Runner Mud Motor Kit

The old engine number was 305442-0527-F1. The new engine number is 305442-0636-F1

With having the gas tank mounted on top of the engine, we highly recommend getting the Wire Muffler Guard and Heat Shield to help protect your gas tank. We also offer a 90-degree Exhaust Elbow which helps redirect the exhaust gases downward.

When using a 16hp or 18hp vanguard engine with our Medium Swamp Runner Kit, you will need this Oil Filter Adapter. With the engine mounted to the kit, the engine base side rails prevent the complete removal of the oil filter. This part will fix that.
