Product Description

2018 Honda Marine BF25 20 in Outboard Motor


Perfect for 14-16 ft. fishing boats, pontoon boats or small runabouts, the BF25 delivers big power and torque, thanks to its whopping 552 cc displacement. It has an ultra-smooth 3-cylinder design, the convenience and precision of up front tiller controls, a Fresh Water Flushport and Gas-assist Tilt.

Performance and Efficiency

Four-Stroke Engine Design: World-renowned Honda quality, proven reliability with no oil mixing.

Reliability and Durability

Over-Rev Protection: Standard rev-limiter protects the engine from severe damage caused by over-revving.

Over-Rev and Overheat Warning Systems: Standard over-rev and overheat warning systems offer peace of mind and protect your investment.

Fresh Water Flushport: Allows easy hook-up to fresh water supply to flush debris and salt water out of the engine, extending the life of the outboard (optional Flush Kit required).

Shallow-Water Drive: Allows the engine to run in a tilted position at low-throttle settings – greatly reducing the risk of engine damage while navigating in shallow water.

Sacrificial Anodes: The BF25 has 1 internal and 2 external sacrificial anodes to protect metal components from corrosion.

Three-Year Warranty: The best outboards in the industry are backed by the best warranty in the business, 3 years parts and labour.

Convenience and Ease of Use

Forward-Mounted Shift Lever (Tiller Models): Allows for easier shifting, especially when docking or in tight access areas.

Regulated, High-Output Charging System: A 10-amp charging system is standard on electric-start models and is equipped with a solid-state regulator/rectifier for easy hook-up.

Emergency Stop Switch/Safety Lanyard: The boat operator clips the lanyard to his or her wrist, which will activate the safety stop switch if the operator leaves the helm.

Standard Fuel Tank, Hose and Propeller: A 25-litre fuel tank, fuel hose and aluminum propeller are included as standard equipment.
