Performance and Efficiency
- Honda Four-Stroke Engine Design: The BF9.9s utilize a, twin cylinder, in-line, OHC design powerhead. World-renowned Honda quality combines proven reliability and quiet operation with no gas-oil mixing.
- Pendulum-Motion Vibration Dampening: An exclusive Honda feature, the pendulum-motion mounting system for the powerhead helps absorb the vibration, including longitudinal vibration, which was difficult to reduce successfully by conventional rubber mounts. The pendulum mount does this without the use of a heavy balancer shaft, which also significantly reduces overall weight.
- Increased Reverse Thrust: When reversing, the exhaust gases are diverted through additional exhaust relief ports above the cavitation plate, allowing the propeller to back up into clean, bubble-free water, thereby increasing reverse thrust.
- Remote-Control Model: A fully-remote-control BF9.9 model (LRTC) is available. Complete with control box and steering tube for a clean installation.
Reliability and Durability
- PGM-IG Ignition: PGM-IG ignition provides reliable starts and optimum ignition timing enhancing running performance across the entire speed range.
- Complete Engine-Management System: Electronically controlled monitoring system protects the engine components from over-revving, low engine-oil pressure and overheating.
- Regulated Charging System: A high-quality regulator/rectifier is standard on all models to prevent overcharging the battery.
- Fresh Water Flushport: Allows easy hook-up to fresh water supply to flush debris and salt water out of the engine, extending the life of the outboard. (optional Flush Kit required)
- Shallow-Water Drive: Allows you to run in shallow water with the engine raised to reduce the risk of damage to the lower gearcase.
- 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.
- Three-Year Warranty: The best outboards are backed by the best warranty, 3 years parts and labour.
Convenience and Ease of Use
- Auto-Choke System: An automatically controlled start-up fuel-enrichment system ensures optimum air-fuel ratio to the engine, eliminating the chores of choke operation and greatly simplifying engine start-up (electric-start models only).
- Lightweight, Rounded Design: Easy to transport, ideal for 10-12 ft. fishing boats, inflatables or for auxiliary sail and trolling power. Also, the BF9.9’s rounded ergonomics won’t catch fishing lines as easily.
- High-Output Charging System: All electric-start models are fitted with a high-output charging system that will deliver an amazing 12 amps at only 3,000 rpm to keep your electronics working and batteries charged. Manual-start models have 6 amps.
- Easy-Pull Starting: The programmed-ignition system sets the ignition system during start-up to reduce the effort required to pull start the engine.
- Forward-Mounted Shift Lever: Allows more control and comfort in shifting.
- Quick-Twist Throttle Friction Adjuster: A simple twist of the throttle friction collar located right at the throttle grip allows you to adjust the throttle tension up or down, minimizing driver fatigue.
- Front-Mounted Steering-Friction Adjuster: A quick-adjust lever design located just above the transom bracket allows for precise adjustments at your fingertips.
- Integrated Carrying Handle: A convenient, foldaway carry handle is situated at the exact horizontal balance point of the engine so that the engine carries more easily in a level position.
- Long Tiller Handle: The BF9.9 tiller models use a long tiller handle for increased control and reduced steering effort. The tiller handle is also made of lightweight composite for increased strength and weight reduction.
