Eldon Dwyer, of New Mexico, designed this two-cycle, water-cooled engine to power his model hydroplane in the early 1980s. This prototype is machined from bar stock except for the cylinder and head assembles. These he acquired from K&B Engines, Lake Havasu, Arizona. The 6-cylinder engine is 12″-long, 5″-wide, and 5″-high.
