The 135 horsepower BF135 delivers some of the most advanced technology ever seen in an outboard engine: it boasts Honda's exclusive Dual Stage Induction and a variable air intake manifold that delivers top performance at every speed.
Combining these features with Honda's exclusive Lean Burn Feedback - which automatically adjusts the air/fuel mixture according to speed and load to maximize fuel efficiency - the BF135 delivers more power from less fuel. And long-term durability is ensured with Honda's Three Way Cooling System (in which the cylinder head runs slightly cooler than the cylinder block - greatly reducing engine wear). Expect awesome power, less refuelling and far less maintenance over many boating seasons.
Honda's 2.4l, 135 hp BF135 is based on the engine that powers the incredibly reliable Honda Accord, the Honda CR-V and the Honda Element.
BLAST
A quick movement of the throttle control activates the BLAST TM system, advancing the ignition curve aggressively. 'Hole shot' is vastly improved as more horsepower gets the hull up on plane quicker.
WORLD FAMOUS QUALITY
By sharing many components with the Honda Accord and CRV automobiles, the BF135 gains years of proven Honda engineering and reliability.
DUAL OVERHEAD CAM (DOHC)
A powerful, compact 24-valve DOHC design creates more valve lift to pull in more air for increased horsepower. Lowmaintenance design allows easy adjustment of the rocker arms. No multiple shims or trial-and-error adjusting needed.
DUAL STAGE INDUCTION
A variable air intake manifold delivers top performance at every speed. At low speeds, air passes through a long intake runner, increasing lowend torque. Above 3500rpm, shutter valves open to shorten the air’s path, boosting air flow for more high-end torque. The result is a simple, compact design that delivers top performance at every speed.
40AMP BATTERY CHARGING POWER
Honda’s proven 'on demand', 51amp belt-driven alternator reduces heat buildup and provides superior battery charging capability. 30amp at 1000rpm and 40amp+ above 2000rpm.
NMEA2000 COMPATIBLE
The BF135 can communicate with onboard electronics to deliver a widerange of information to head-unit displays. When networked with a Lowrance HDS unit, for example, engine data such as speed, revs, temperature, fuel usage and other data can be displayed on the unit’s screen.
ENGINE COMMAND
The ECM receives constant input from 18 different sensors to deliver instant starts, smooth operation, strong performance and excellent fuel efficiency.
ECOmo
Along with Honda’s Programmed Fuel Injection, the BF135 incorporates Lean Burn Control technology, which allows combustion to operate on a leaner air/fuel ratio than stoichiometric air/fuel. An O2 sensor, together with the ECM, precisely controls the air/fuel mixture for the best fuel economy at cruise setting. The mode in which lean burn control is used during cruising to achieve higher fuel economy is referred to as ECOmo (Economy Controlled Motor).
3 WAY COOLING SYSTEM
Three separate cooling systems keep the cylinder head cooler for more long-term durability.
LAF & KNOCK SENSOR
Linear air/fuel and knock sensors help determine the correct fuel flow and ignition curve. Improves overall engine operation and efficiency plus prevents engine damage.
ENGINE ALERT SYSTEM
With Honda’s Engine Alert System, the ECM monitors vital engine functions and prevents engine damage by alerting the operator of overheating, low oil PSI, over-rev, water in fuel, battery condition, and critical engine functions.
POSITIVE LUBRICATION
A crankshaft-driven, automotive-style trichoid oil pump ensures the longterm durability of critical engine components.
MULTI-PORT PROGRAMMED FUEL INJECTION (PGM-FI)
Delivers the precise amount of air/fuel to each cylinder. The result is quick starts, instant throttle response and low fuel consumption.
SINGLE LATCH COWL
Four securing points to ensure a water-tight seal, along with a convenient front-mounted single latch.
SEALED STARTER
The starter motor is inverted into a sealed chamber that protects the starter bendix drive from the elements.
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.
STAINLESS STEEL
Steering Arm, Tilt Tube and all Shafts. Durability with long-term corrosion resistance!
BUILT-IN PILOT TUBE
Built-in pilot tube in the gear case eliminates the need to drill holes in your boat for installation.
