📖 Model Background

The Yamaha 50 HP F50D 4-stroke outboard, produced from 2004 to 2010, offered a perfect balance of fuel efficiency, quiet operation, and reliable mid-range performance. Built on the same 996 cc SOHC 4-cylinder platform as the F60D, the F50D delivered slightly lower horsepower while maintaining strong torque and smooth acceleration through electronic fuel injection (EFI). Its lightweight design and clean emissions made it ideal for aluminum fishing boats, small center consoles, and family runabouts. With Yamaha’s signature engineering, the F50D became a dependable choice for boaters needing versatility without sacrificing economy or power.
