Every Argo utv can be equipped with a outboard motor bracket and up to a 9.9hp outboard or trolling motor. Its best to use a long shaft outboard as cavitation can be an issue with short shaft models. The tires alone will propel the vehicle up to 3.5mph on average depending on what tires your Argo has installed.
If you use you Argo in marshes, swamps, or open water often it's best to grease your outer bearings at least every 10 hours or after you are done in the water before storage. Water intrusion into the bearings and when stored for periods of time can cause rust in the bearings and premature bearing failure. Take the 10 minutes after each trip and grease those bearings and know that your vehicle's drive-terrain will last for many years and be ready for the next hunt.
Saltwater can be very corrosive and washes grease out of bearings very quickly. Always power-wash your Argo after each use in saltwater to prevent surface rust on chains and any metal parts. Remember to always lube your chains after power-washing. A quick greasing of the outer bearings weekly if used in saltwater is a good idea to prevent grease washout.
If your interested in buying a new Argo the factory has a zinc primer and powdercoated black paint option as well as a new galvanized option for saltwater that can be assembled right from the factory. On the galvanized option, all black metal parts would be galvanized silver including rims.
