He's 88, lives in Elk River and has a 75-year-old tale to tell.<br /><br />Kemper has unraveled the mystery of the antique outboard motor that Rich Boedigheimer of Big Lake pulled through the ice recently while fishing on Little Pine Lake near Perham.<br /><br />I wrote about Boedigheimer's find last week. He was fishing with a friend, Robbie Yeager of Minneapolis, in an ice-fishing house last month when he lowered his underwater video camera into the water and spotted the old motor lying on the lake bottom. With much effort, the pair fished the 1920s-era motor out of the lake.<br /><br />Since then they've tried to learn what kind of motor they found, who lost it, when and how.<br /><br />Kemper had most of the answers. The motor, as suspected, is a rare 1928 Super Elto Quad, a four-cylinder, 18-horsepower developed by Evinrude Outboard founder Ole Evinrude.<br /><br />Rich Boedigheimer pulled this motor out of Little Pine Lake.Star Tribune"My dad, Bernie, bought that motor," Kemper recalled last week. "Dad tried it out, and he didn't like it. It was a hard motor to handle. But my brother, Jim, loved it."<br /><br />The Kempers had a cabin on Little Pine Lake. Jim Kemper was in high school, probably in the early 1930s, when he took the boat and motor out for a fateful spin.<br /><br />"It was a high-speed motor, and he had a lot of fun with it," Bob Kemper said. "One day as he was driving it, and the motor jumped right off the boat. We dragged that area of the lake over and over again, but we never did find it.<br /><br />"Jim felt kind of bad about it, but my dad was kind of glad to get rid of it," Kemper said. His brother died two years ago. <br /><br />Boedigheimer tracked Kemper down after getting tipped off by a Perham resident who saw the story in the Star Tribune.<br /><br />"It was great to find out the story behind it," Boedigheimer said<br />
