1988-1993 432 Brut #2323 series WetJet 2-cycle engine. Nearly brand new in original box. This was used on a test bench for research and development for the Ellison throttle body/carburetor installation onto smaller engines. Minimal run time, never installed in watercraft, snowmobile or ultralight aircraft but could easily fit those applications. Tapered crankshaft. Resembles Rotax 447 & 503 2-stroke line of engines. Reasonable offers entertained.
