ENGINE FEATURES
|
4-Stroke Design
World-renowned Honda quality combines proven reliability and superior fuel efficiency, with no oil mixing. |
Center Mount Tiller
A new ergonomically designed tiller handle is 8" longer and angled 5" higher for improved handling. A front-mounted shift lever, power tilt and trim switch, and engine alert lamps provide added convenience. |
Power Trim/Tilt
Allows user to trim the unit for maximum performance and handling.
Trim Range: - 4° to +12°
Tilt Range: 67° |
3 to 3 Induction
A compact 3-cylinder, 3-carburetor design utilizes one carburetor per cylinder. More responsive than competitive throttle bodies with long intake runners, the design provides smooth, quiet operation, along with instant throttle response and performance. |
Offset Crankshaft Design
The BF40’s exclusive crankshaft design locates the powerhead directly over the transom pivot point to reduce vibration and improve performance and handling |
PGM Ignition
A reliable microprocessor accurately controls ignition timing during start-up and across the entire RPM range, providing optimum overall operation. |
Auto Start Enrichment (ASE)
Just like a fuel injection system, Auto Start Enrichment automatically adjusts the air-fuel mixture for quick, easy starting and warm-ups. |
Non-Linear Mounting System
Patented non-linear rubber mounts provide smoother operation at all engine speeds. |
Positive Lubrication
A crankshaft-driven, automotive-style trochoid oil pump ensures long-term durability of critical engine components. |
Engine Alert System
Audio and visual cues combine with RPM reduction circuits to alert the operator of overheating, low oil PSI and over-revving to prevent engine damage. |
Forced Air Ventilation
Unique air intake on the top of the cowl allows cooler air to enter and warmer air to escape. The ventilation system reduces under-the-hood operating temperature, improving performance and long-term durability of the electrical components. |
High Output Charging System
The BF40’s 10 amp charging system ensures that batteries remain charged. |
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. |
Easy Maintenance
Front-mounted oil filter and oil fillers simplify maintenance, while "screw-type" valve adjusters reduce maintenance costs. |
Gas Assist Tilt
A gas-filled cylinder makes it easy to tilt the engine for running in shallow water, or to raise it completely out of the water for protection. |
Built-In Pitot Tube
Built-in pitot tube in the gear case eliminates the need to drill holes in your boat for installation. |
