Chrysler 4.9 Marine Outboard Engine The Chrysler 4.9 is a compact, gasoline-powered outboard engine engineered for reliable marine propulsion in small watercraft. Introduced in 1973, this vintage two-stroke design delivers straightforward power for auxiliary or primary drive systems, embodying the era’s emphasis on simplicity and durability in harsh saltwater or freshwater environments. Key technical specifications include a twin-cylinder configuration with a displacement of 123 cm³ (0.123 liters), producing 4.9 horsepower (3 kW) at optimal RPM. Weighing just 16.8 kg (37 lbs), it features gasoline fuel induction and an outboard mounting setup, with no specified gear reduction or compression ratio, underscoring its minimalist architecture. The absence of advanced drive systems or electronic controls highlights its manual-start operation, ideal for low-maintenance setups. In marine applications, the Chrysler 4.9 excels through its lightweight portability and corrosion-resistant construction, reducing transom stress on lightweight hulls and enhancing overall vessel stability. Its compact footprint facilitates easy installation and removal, making it a practical choice for trailered boats or seasonal storage. The two-cylinder layout ensures smoother operation than single-cylinder alternatives, minimizing vibration while promoting fuel efficiency in calm waters. Performance-wise, this engine provides dependable low-end torque for leisurely cruising, though its modest output limits top speeds to auxiliary roles rather than high-performance demands. It thrives in moderate conditions, offering consistent throttle response without the complexity of modern EFI systems. Ideal for dinghies, tenders, fishing skiffs, or educational model boats, the Chrysler 4.9 suits hobbyists, collectors, and budget-conscious mariners seeking a no-frills propulsion solution. Its vintage reliability continues to appeal in niche scenarios where portability and ease of service outweigh raw power, proving that classic engineering remains a timeless asset on the water.
