Honda 20 HP Outboard Motor - Model BF20D3SH
The Honda BF20D3SH is a lightweight and dependable 20 HP short shaft outboard, designed for small boats and dinghies that demand portable power. Weighing only 104 lbs, it’s one of the lightest in its class while still delivering impressive thrust.
Powered by a 350 cc twin-cylinder SOHC engine, this outboard offers smooth and efficient performance. Its manual start and tiller steering keep operation simple and reliable, while the manual trim and tilt system provides easy control in shallow water conditions.
Built with Honda’s PGM-IG ignition and saltwater-rated durability, the BF20D3SH ensures longevity in both freshwater and marine environments. A 6-amp alternator supplies power for basic electronics, making it versatile for fishing, recreation, and work applications.
