Legendary Honda Reliability
Based on the Honda Civic Automobile, the BF75 and 90HP retain all the engineering excellence, low operational costs and proven durability of Civic heritage.
4 to 4 Induction
A fuel-efficient 4-cylinder, 4-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.
Torsion Dampener
Sometimes called a flywheel, the torsion dampener’s location near the base of the powerhead lowers the center of gravity for improved handling and hull maneuverability.
Top Mounted Electronics
Alternators, ignition and other critical electrical components mounted near the top of the powerhead to stay cool and dry for increased dependability.
SOHC 3 Valve Design
The BF90’s powerful 1.6L, 4-cylinder design utilizes a single overhead cam, and two intake valves to deliver maximum torque and power.
High Output Charging
16 Amps ensure that battery charge is maintained while operating electronics and other accessories.
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.
Sealed Starter
The starter motor is inverted into a sealed chamber that protects the starter bendix drive from the elements.
Non-Linear Mounting System
Patented non-linear rubber mounts provide smoother operation at all engine speeds.
Forced Air Ventilation
A unique air intake on the top of the cowl allows cooler air to enter and warmer air to escape. Reducing the operating temperature improves performance and long-term durability of electrical components.
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
Easy "screw-type" valve adjuster system requires no shims and reduces maintenance costs. Front-mounted oil filter and oil filler make for easy maintenance.
Digital CD Ignition
A reliable microprocessor accurately controls ignition timing during start-up and across the entire RPM range, providing optimum overall operation.
Built-In Pitot Tube
Built-in pitot tube in the gear case eliminates the need to drill holes in your boat for installation.
Tiller Model Available
All controls at your fingertips.
Ultra Low 3 Star Carb Emissions
Environmentally friendly technology.
