Reliable, Efficient 4-Stroke Design
World-renowned Honda quality combines proven reliability and superior fuel efficiency, with no oil mixing.
Lightweight And Compact
The BF4 Outboard's lightweight, compact design makes it perfect for small tenders, sailboats, jon boats, and inflatables. Weighing in at only 60 pounds, this motor is easy to transport.
Easy To Start And Stop
You'll be impressed with how easy it is to start the BF4. The decompression mechanism opens the exhaust valve during the starting process. This reduces the amount of force needed to start the motor. Starting is easy, every time. The one-push stop switch makes it just as easy to shut off the motor. Pressing the stop button once safely shuts off the motor without it re-starting.
Large Capacity Internal Fuel Tank For Best In Class Run Time
The 1.5L internal fuel tank provides enough fuel for over 40 minutes of wide open throttle operation.

Honda's exclusive design optimizes the isolation mounts to minimize the transfer of vibration to both the tiller handle and the transom. The custom rubber mounts absorb vibration, resulting in a motor with among the lowest handle vibration in its class.
Easy To Carry And Install
Enlarged carrying handles provide superior portability and ease of installation.
Convenient Fold-Up Or Down Tiller Handle
The tiller handle's compact design allows for easy transportation and storage.
Quietest In Its Class
The BF4 leads its class in noise reduction from low to high speed.
Large Displacement Engine For More Power
Water-cooled, single cylinder design for better low to mid-range power.
Twist Grip Throttle Is More Comfortable To Use
Allows for precise throttle control. A unique throttle tensioner minimizes driver fatigue.
True 5-Year Warranty For Unmatched Peace Of Mind
Honda's True 5 Warranty is the best in the business. This transferable, non-declining warranty is the same on the first day as it is on the last.
4-Front Corrosion Protection System Fights The Elements
A patented, "Double-Sealed" multi-layered paint process, sacrificial anodes, stainless steel technology, and waterproof connectors enhance corrosion protection.
Double Alerts Protect Your Engine
A Low Oil Alert combined with an RPM reduction feature protect the engine from severe damage if the oil reaches a low pressure.
Shallow Water Drive
An innovative shallow water drive feature lets you tilt the motor up, allowing you to easily operate in shallow areas. Shallow water drive greatly reduces the risk of engine damage.
The BF4 features full forward, neutral, and reverse shifting. A safety lockout system allows the engine to be started in neutral gear only.
Positive Lubrication For Better Durability
A crankshaft-driven, automotive-style trochoid oil pump ensures long-term durability of critical engine components.
