Did You Know...
...that it was melting ice cream that inspired the invention of the outboard motor? It was a lovely August day and Ole Evinrude was rowing his boat to his favorite island picnic spot. As he rowed, he watched his ice cream melt and wished he had a faster way to get to the island. At that moment the idea for the outboard motor was born!
