The Yamaha 5BS 661 is a classic air-cooled, two-stroke outboard motor produced between 1973 and 1986 . Known for its simplicity and reliability, this 5hp engine was designed to be lightweight and portable, making it a popular choice for small fishing boats and tenders. Finding an original printed manual today can be difficult due to its age, but enthusiasts often rely on digitized service guides and community-sourced documents to maintain these vintage units. Yamaha 5BS 661 Key Specifications The 5BS series is distinct because it is air-cooled , which eliminates the need for a water pump and reduces maintenance complexity in some environments. Engine Type: Single-cylinder, two-stroke, air-cooled. Displacement: 103 cc. Maximum Output: 5 HP at 4500 RPM. Weight: Approximately 19 kg (42 lbs), making it highly portable. Ignition: Older models use breaker points, while some variations may have CDI. Fuel Mix: Pre-mix gasoline and 2-stroke oil at a 50:1 ratio. Essential Maintenance for the 5BS 661 Since these engines are decades old, following a rigorous maintenance schedule is the only way to ensure they remain functional. Spark Plugs: Regularly inspect and clean the spark plug. Fouled plugs are a common reason for "no-start" issues in two-stroke engines. Carburetor Cleaning: Modern fuels can leave residue that clogs the small jets in the carburetor. Periodically cleaning the carb and replacing old fuel is essential. Reed Valve Inspection: A damaged reed valve can cause exhaust to blow back through the carburetor or prevent the engine from idling. Gear Oil: Change the gearcase oil annually or every 100 hours of use to protect the internal gears. Propeller Check: Inspect the propeller for damage and grease the shaft to prevent it from seizing. Troubleshooting Common Issues If your Yamaha 5BS 661 is struggling to run, focus on these areas commonly noted in service manuals: Hard Starting: Often caused by old fuel, a clogged fuel filter, or a fouled spark plug. Stalling Under Load: This may indicate a problem with the reed valves or an incorrect fuel-to-air mixture in the carburetor. Oil Leaks: Inspect the gaskets and seals, especially around the gearcase and cylinder head.
