4-Stroke Design

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

 Available with Power Thrust Design (BFP) – better performance

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.

Reverse Exhause Relief – increased manueverability (BFP models)

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 – 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.

Easy One Hand Starting

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!

PGM Ignition

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

Pendulum Mount System

Honda’s exclusive triangulated rubber mount system absorbs vibration and provides unbelievably smooth operation.

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.

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.

Positive Lubrication

A crankshaft-driven, automotive-style trochoid oil pump ensures long-term durability of critical engine components.

Engine Alert System

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


One-piece cast head and engine block

A one-piece cast head and engine block provide additional strength, while lowering the engine’s weight.

Ultra Low 3 Star CARB Emissions

Environmentally conscious technology. All Honda Marine engines exceed the highest CARB 3-Star rating to meet the rigorous California Air Resource Board’s standards.

True 5 Warranty

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.

High Output Charging

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 spe

Integrated Carrying Handle

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.
