ENGINE FEATURES
|
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. |
