BF15 – BF20
THE BEST OF BOTH WORLDS
Like the highest output charging system in their class, giving you plenty of power for all your electronics, even when trolling.
Add in easy one-hand starting, shallow water drive, power tilt, and much more, and you’ve got the ideal combination of power and portability.
PORTABLE POWERHOUSE
LARGE DISPLACEMENT – BETTER PERFORMANCE
At 21.4 cubic inches, the BF15 and 20 have one of the largest displacements in its class. Along with the long-stroke design, this provides optimum torque throughout the RPM range.
PGM IGNITION
A reliable microprocessor accurately controls ignition timing during start-up and across the entire RPM range, providing optimum overall performance.
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.
3 STAGE CARBURETION – BETTER FUEL ECONOMY
Conventional 2-circuit carburetors go directly from a lean mixture at idle to a rich setting at full throttle. The BF15 and 20 add a third stage for better economy and smoother operation.
POWER TILT AVAILABLE
Conveniently allows user to tilt the unit out of the water. At low speeds acts like a power shallow-water-drive device, permitting access to the shallow water areas.
LEGENDARY RELIABILITY
eNGINE ALERT SYSTEM – KEEPS YOU INFORMED
The integrated warning system protects the engine from severe damage due to low oil, over-revving and overheating.
4-FRONT CORROSION PROTECTION SYSTEM – FIGHTS THE ELEMENTS
A patented, “Double Sealed” multi-layered paint process. Sacrificial anodes and stainless steel technology, along with waterproof connectors, all enhance corrosion protection.
easy starting
Easy one-hand starting
A built-in decompression release and digital CDI system set the BF15 and 20’s ignition timing. This reduces the effort required to pull-start the engine by hand by 40%!
Auto start enrichment – easy starts
Auto Start Enrichment acts as an automatic choke. Just like a fuel injection system, it automatically adjusts the air/fuel mixture for quick, easy starting and warm-up.
CONVENIENT CONTROLS
CONVENIENT, UP FRONT TILLER CONTROLS
A convenient front-mounted shift lever allows fingertip shifting. The Twist Grip Throttle & Tensioner minimize driver fatigue.
LONGER TILLER HANDLE – BETTER CONTROL
A convenient longer tiller handle improves control and reduced steering effort. The extended handle is made of a lightweight composite, increasing its durability while decreasing the motor’s weight.
EZ STEER FRICTION CONTROL
A unique lever design allows you to precisely adjust steering tension for improved control and comfort.
EASY OWNERSHIP
LIGHTWEIGHT DESIGN
The lightest 4-stroke model in their class, the BF15 and 20 are easy to transport and convenient to mount.
INTEGRATED CARRYING HANDLE – EASIER TRANSPORT
A integrated carrying handle makes transporting the engine a breeze. The convenient, foldaway carry handle is situated at the exact top/bottom balance point of the engine. This means the engine carries more easily in a level position.
HIGH OUTPUT CHARGING
The BF15 and 20 have the largest alternator in their class. These motors generate 12 Amps at only 3000 RPM. This helps to maintain battery charge and keep electronics running at trolling speeds.
PENDULUM MOUNT SYSTEM – SMOOTH OPERATION
Honda’s exclusive triangulated rubber mount system absorbs vibration and provides unbelievably smooth operation.
