BF20

At 21.4 cubic inches, the Honda BF20 outboard is the king of power - with the largest displacement of any engine in its class. And it's also the lightest 2o hp engine there is.

The high-torque 4-stroke BF20 features a 12 AMP alternator to keep the battery charged at any speed. And it's one of the most convenient outboards on the market, with EZ-steer Friction Control that allows you to adjust steering tension for comfort and better handling.


Features

FOUR-STROKE ENGINE DESIGN
World-renowned Honda quality combines proven reliability and superior fuel efficiency, with no oil mixing.

REVERSE EXHAUST RELIEF
Additional exhaust relief above the cavitation plate allows the prop to run in clean, exhaust-free water producing more thrust.

EASY ONE HAND STARTING
Working together, a built-in decompression release and Digital CDI system set the ignition timing during start-up. Just 60% of the normal effort is required to pull-start the engine by hand!

POWER TILT
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.

AUTO START ENRICHMENT
On electric start models, automatically adjusts the air/fuel mixture for quick, easy starting and warm-up.

SHALLOW WATER DRIVE
On manual models allows you to run in shallow water and greatly reduces the risk of engine damage.

POSITIVE LUBRICATION
A crankshaft-driven, automotive-style trochoid oil pump ensures critical engine component long-term durability.

INTEGRATED CARRYING HANDLE
A convenient, foldaway carry handle is situated at the exact top/ bottom balance point of the engine, so that the engine carries more easily in a level position.

3 STAGE CARBURETION
While conventional two-circuit carburetors go directly from a lean mixture at idle to a rich setting at full throttle, the BF20 adds a third middle stage for better economy and smoother, stronger operation.

PGM IGNITION
A reliable microprocessor accurately controls ignition timing during startup and across entire rpm range, providing optimum overall operation.

ENGINE ALERT SYSTEM
The integrated warning system protects the engine from severe damage due to low oil, over-revving and overheating.

CORROSION PROTECTION SYSTEM
A patented 'double sealed' multi-layered paint process. Sacrificial anodes and stainless steel technology, along with waterproof connectors,all enhance corrosion protection.

FRESH WATER FLUSHPORT
Flushes debris and saltwater out of the engine, extending the life of the outboard.

LONGER TILLER HANDLE
The BF20 has a convenient longer tiller handle for increased control and reduced steering effort. The extended handle is made of a new lightweight composite for increased durability and weight reduction.

UP FRONT TILLER CONTROLS
The convenient Forward Mount Shift Lever allows fingertip shifting. Twist Grip Throttle and Tensioner allows for superior throttle friction control, minimising driver fatigue.

EZ STEER FRICTION CONTROL
Unique lever design allows operator to precisely adjust steering tension for improved control and comfort.

GAS ASSIST TILT
Gas Assist function makes it easy to tilt the engine for running in shallow water, or raise it completely out of the water for protection.
