The combination of the 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 is improved maneuverability and performance.
The Power Thrust model's exhaust relief feature creates more power in reverse by minimizing cavitation around the propeller blades. The exhaust relief is located above the cavitation plate, allowing the prop to run in clean, exhaust-free water.
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.
Working together, a built-in decompression release and digital CDI system set the ignition timing during start-up. This greatly reduces the effort required to pull-start the engine by hand!
A reliable microprocessor accurately controls ignition timing during start-up and across the entire RPM range, providing optimum overall operation.
Honda's exclusive triangulated rubber mount system absorbs vibration and provides unbelievably smooth operation.
A unique lever design allows you to precisely adjust steering tension for improved control and comfort.
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.
A patented, "Double Sealed" multi-layered paint process. Sacrificial anodes and stainless steel technology, along with waterproof connectors, all enhance corrosion protection.
A crankshaft-driven, automotive-style trochoid oil pump ensures long-term durability of critical engine components.
The integrated warning system protects the engine from severe damage due to low oil, over-revving and overheating.
A one-piece cast head and engine block provide additional strength, while lowering the engine's weight.
Environmentally conscious technology. All Honda Marine engines exceed the highest CARB 3-Star rating to meet the rigorous California Air Resource Board's standards.
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.
The BF9.9 provides 2 Amps at 1000 RPM and an amazing 12 amps at 3000 RPM. This helps to maintain the battery charge or keep electronics going - even at trolling speeds.
Easy to transport, BF9.9 is perfect for small boats, dinghies or auxiliary. The ergonomic design is rounded to avoid catching fishing line.
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.
A convenient front-mounted shift lever allows fingertip shifting. The Twist Grip Throttle & Tensioner minimize driver fatigue.
Conveniently tilts the engine out of the water for easy lift-off and 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.
