The engine
Joost™ was founded upon its novel 2-stroke internal combustion engine, with which it plans to disrupt multiple product markets, starting with the marine outboard
The Joost engine has all the weight, power and simplicity benefits of a 2-stroke engine, but with the emissions and efficiency performance of modern 4-strokes.
Its opposed piston, single cylinder design is scalable from 5hp to 50hp, perfectly balanced for whisper-quiet operation, and multi-fuel compatible.
