What you're looking at is a RiverPro jet boat made for navigating shallow water. Owner Danny LaVoie of Snake Creek, GA says it can run in about 3 inches of water. It has no prop, instead pushing air out the back much like a jet ski. It has an Optimax 200 inboard engine. In the photo the engine compartment is open. High speed is about 50 miles an hour. The hull is made of thick aluminum, with a coating.
We're sitting with Danny and his buddies in Potato Creek. It is shallow with lots of underwater timber. Perfect for a shallow water boat.
