Dingbat - By WILLIAM D. JACKSON. You can build this most-fun-per-horsepower waterscooter on Saturday and have it in the water for a full day of boating thrills on Sunday. There's some flashy performance in your small outboard motor that will surprise you when running it on Dingbat. Water-Scooter rodeos, slalom races, and obstacle courses - well, the old pond just won’t he the same again when you and your friends show your skill at these and other water sports with a fleet of Dingbat scooters. With motors up to 10 hp and semi—mono-coque hulls that are built with space-age techniques but use ordinary lumberyard materials, you can have your share of safe boating fun without putting a strain on the budget or missing another day of the boating season.
