A video on YouTube. In Maker & Builds, a Krater category.

Summary by Krater

Colin Furze builds a homemade boat paddle powered by an electric drill and tests it on the river, concluding that a grinder works better than a drill for spinning the propeller.

What it concludes

A drill is not powerful enough to spin the boat paddle propeller effectively in the water.
Switching the drill to a grinder provides more speed and makes the homemade propeller system work.
