Fuel System Carburetion: Multiple carburetors (likely 2 or 3) depending on engine configuration, requiring specific tuning and rebuilding procedures. Ignition System Ignition Type: Magneto ignition system, known for its reliability and self-contained power generation. Transmission Standard Type: Outboard lower unit gearbox with forward, neutral, and reverse. Features Lubrication: Requires specific marine gear oil, with detailed change intervals and capacity specified in the manual. Propeller Shaft: Details on propeller installation, removal, and related seals. Dimensions Exterior Overall Length: Not applicable as this is an outboard motor, dimensions refer to motor itself. Weights Dry Weight: Estimated weight for a 120 HP outboard from this era would typically range from 250-350 lbs, but specific details are in the manual. Safety Features Ratings Safety Features: Manual covers operational safety, pre-operation checks, and troubleshooting of safety-related systems. Active Features Emergency Stop: While not explicitly mentioned, the manual would cover any integrated safety shut-off mechanisms. Technology Features Infotainment Instrumentation: Covers gauges such as tachometer, oil pressure, water temperature, and trim position if equipped, along with their associated sending units and wiring. Driver Assistance Trim Tilt System: If equipped with a power trim and tilt system, the manual will cover its hydraulic components, electrical controls, and troubleshooting. Connectivity Wiring Schematics: Detailed wiring diagrams are a key feature, essential for diagnosing electrical issues and understanding component connections. Maintenance Service Intervals Tune Up Interval: Typically annually or every 100 operating hours, detailed in manual. Water Pump Impeller: Recommended replacement every 1-2 years or as per manual inspection due to wear from water flow. Lower Unit Oil Change: Typically every 50-100 operating hours or annually, crucial for preventing gear damage. Fluid Specifications Lower Unit Gear Oil: Requires specific marine lower unit gear oil (e.g., SAE 80W-90 or similar GL-4 rated). Exact specification in manual. 2 Stroke Oil Mix: For a pre-mix outboard, the manual will specify the correct ratio of 2-stroke oil to gasoline and the recommended oil type (e.g., NMMA TC-W3). Known Issues Common Wear Items: Water pump impeller, spark plugs, carburetor jets/gaskets, ignition components, and shift cables are common wear items for outboards of this age. Corrosion Prevention: Manual will likely include guidance on proper flushing and maintenance to...
