2006 Honda BF9.9

The 9.9 HP, 4-stroke Honda BF9.9 outboard engine utilizes our single-overhead-cam design for outstanding power. A programmed ignition system with autostart enrichment gives you fast, easy startup and warm-up. And reverse exhaust relief creates more power in reverse by minimizing cavitation around the propeller blades.

4-Stroke Design
World-renowned Honda quality combines proven reliability and superior fuel efficiency, with no oil mixing.

Power Thrust Design (BFP)
The combination of a lower 2.33:1 gear ratio and the 10" x 6 1/2" Power Thrust 4-blade propeller creates 60% more thrust in reverse and 15% more in forward. The result - improved maneuverability and performance.

Reverse Exhaust Relief
Additional exhaust relief above the cavitation plate allows the prop to run in clean, exhaust-free water - producing more thrust.

Lightweight Design
The 9.9HP is the lightest 4-stroke model in its class, allowing easy transport and convenient mounting to the hull.

Auto Start Enrichment
On electric start models it automatically adjusts the air/fuel mixture for quick, easy starting and warm-up.

Easy One Hand Starting
Working together, a built-in decompression release and digital CDI system set the ignition timing during start-up. Greatly reduces the effort required to pull-start the engine by hand!

PGM Ignition
A reliable microprocessor accurately controls ignition timing during start-up and across the entire RPM range, providing optimum overall operation.

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

High Output Charging
6 Amps at 1000 RPM and an amazing 12 amps at only 3000 RPM to maintain the battery charge and keep electronics going, even at trolling speeds.

Lightweight Rounded Design
Easily transportable, ideal for small boats, dinghies or auxiliary. New ergonomics look great and won't catch fishing line etc. as easily.

Pendulum Mount System
Honda's exclusive triangulated rubber mount system absorbs vibration and provides unbelievably smooth 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 9.9 HPs have convenient longer tiller handles for increased control and reduced steering effort. The extended handle is also 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 & Tensioner allows for superior throttle friction control, minimizing driver fatigue.

EZ Steer Friction Control
Unique lever design allows operator to precisely adjust steering tension for improved control and comfort.

Shallow Water Drive
Allows you to run in shallow water and greatly reduces the risk of engine damage.

Power Tilt
Conveniently tilts the engine out of the water.

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.

Ultra Low 3 Star Carb Emissions
Environmentally friendly technology.
