Evinrude is a dragonfly who is stated to own the fastest boat in Devil's Bayou. He does not speak in the strictest sense but is capable of communicating with others, like Ellie Mae, and the Swamp Folk. His personality is not well developed, but he does seem to be helpful and courageous.
When Bernard and Miss Bianca are in need of a boat to reach the riverboat, the location of Madame Medusa's hideout, one of the locals, Ellie Mae, recommends Evinrude to the pair, as he has the fastest boat around. Evinrude takes the pair to the riverboat and is later asked to round up the other local animals to take part in a rescue of Penny, the young girl that was kidnapped by Medusa.
Evinrude tries to return to Ellie Mae's but is forced to take cover from a swarm of bats. Later on, Evinrude makes the final trip, managing to land in Ellie Mae's coal stove. By this time, Ellie Mae has managed to gather up the neighbors, in wait of a call from Bernard and Bianca. Evinrude is initially too exhausted to give the message but is revived by Ellie Mae's husband, Luke, by a drink, presumably moonshine.
Evinrude leads the charge, and the group is able to successfully defeat Medusa and rescue Penny, Bernard, and Miss Bianca. Evinrude is later seen at the end of the film, accompanying Bernard and Bianca on another mission.
According to Storyboards for The Rescuers Down Under, shown in the book Paper Dreams: The Art and Artists of Disney Storyboards, show that Evinrude would've made a cameo at the end of that film, but it was scrapped for unknown reasons
A walkaround version of Evinrude was produced for the film's original release and was seen at Disneyland and the Magic Kingdom, though has long since been retired. Years later, he could be seen on the Princess and the Frog float in Mickey's Soundsational Parade.
- Evinrude's name and design likely draw inspiration from a company called Evinrude Outboard Motors. Evinrude's method of maneuvering his boat (and the resulting sound), is similar to the outboard boat motors the company manufactures.
- Upon being revived with Luke's moonshine, he emits the same "charging" sound that a bee made in Winnie the Pooh and the Honey Tree. Coincidentally, those bees were also voiced by Jimmy MacDonald.
