If you can find one....Johnson/Evinrude made a family of engines for several years called the Mirage. They were 3-cylinder 2-stroke engines from 25hp to 35hp. The 25hp was built on a 500CC platform originally designated for European class racing. The 35hp was a little larger at 565CC. They are pretty potent for their size and had quite alot of neat features including Quickstart, optical ignition, offset cylinders, TNT on designated models, etc. Am currently running a 25 Mirage on my 15' 6" Gheenoe Classic and first time out it pushed it at 37.5mph on GPS. Have since added a jackplate and just had the prop reworked to take advantage of the added engine height.
