📖 Model Background

The Yamaha F50TLR 4‑stroke outboard, produced from 1999 to 2004, served as one of Yamaha’s early portable mid-range powerhouses. Powered by a 996 cc SOHC inline‑4 engine with multi-point EFI, it generated a reliable 50 HP while weighing approximately 113 kg (249 lb) - making it one of the lightest in its class. The F50TLR featured a high-precision throttle system, labyrinth-style exhaust for reduced noise, and a top-mounted flywheel to protect electrical components from water exposure - resulting in smooth operation, clean emissions, and high dependability. Its portability, fuel efficiency, and quiet running made it a favorite among anglers, inflatables, and small recreational craft during the late ‘90s and early ‘00s.
