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.
