F5 is designed as a small power 4-stroke outboard motor, suitable for personal leisure and entertainment, and used to boats, rubber boats within 5 meters. F5 and F4 come from the same development platform, so they can share most parts. Their light weights, combined with built-in carrying handles and an oil-leak prevention system for on-side storage capability create true portability. Add to that their efficiency, performance and reliability and these pint-sized powerhouses are perfect for all sorts of light duty.
