Honda BF105 Jet Drive

The BF105 Jet Drive engine delivers some of the most advanced technology ever seen in an outboard. It boasts VTEC Technology that delivers more power, torque and efficiency at every speed.

Combined with Honda's exclusive Lean Burn Feedback, which automatically adjusts the air/fuel mix according to speed and load to maximize fuel efficiency, you get an engine that delivers more power with less fuel.

And to insure long term durability, Honda engineers designed a Three Way Cooling System. The cylinder head runs slightly cooler than the cylinder block, greatly reducing engine wear. Expect awesome power, less refueling, and far less maintenance over many boating seasons. Take a look inside at the engineering of this incredible powerhouse. Honda's 105 hp is 2.4 liters.based on the same engine that powers the incredibly reliable Honda Accord, CR-V and Element.

World Famous Quality
By sharing many components with the Honda Accord, CRV and Element automobiles, the BF 150 and 135 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. Low-maintenance design allows easy adjustment of the rocker arms. No multiple shims or trial-and-error adjusting needed.

Variable Valve Timing & Lift Electronic Control system achieves the best of both worlds, by utilizing mild cam lobes to operate the intake valves at low RPM-then, at 4500 RPM, engaging a "high output" cam lobe for high RPM operation.

VTEC offers a superior blend of power, torque and fuel efficiency.

Lean Burn Feedback Control
Utilizes a Linear Air-Fuel Sensor, along with the Engine Command Module, to automatically adjust the air-fuel mix according to speed and load - maximizing power throughout the RPM range and providing twenty percent greater fuel economy in the cruise mode from 2000 to 4500 RPM.

3 Way Cooling System
Three separate cooling systems keep the cylinder head cooler for more long-term durability.

40 AMP Alternator
Honda's proven "on demand," belt-driven alternator reduces heat buildup and provides superior battery charging capability-30 Amps at 1000 RPM and 40+ Amps above 2000 RPM.

Engine Command
The ECM receives constant input from 18 different sensors to deliver instant starts, smooth operation, strong performance and excellent fuel efficiency.

Dual Stage Induction
A variable air intake manifold delivers top performance at every speed. At low speeds, air passes through a loing intake runner, increasing low-end torque. Above 3500 RPM, shutter valves open to shorten the air's path, boosting air flow for more high-end torque.
Benefit: The result is a simple, compact design that improves overall operation.

LAF & Knock Sensors
Benefit: Improves overall engine operation and efficiency plus prevents engine damage.

Engine Alert
The ECM monitors vital engine functions and prevents engine damage by alerting the operator of:

* Overheating
* Water in Fuel
* Low Oil PSI
* Battery
* Over-Rev
* Critical Engine Function

Multi-port Programmed Fuel Injection (PGM-FI)
Delivers the precise amount of fuel/air to each cylinder. The result is quick starts, instant throttle response and low fuel consumption.

Single Latch Cowl
4 securing points to ensure a water-tight seal, along with a convenient front-mounted single latch.

Positive Lubrication
A crankshaft-driven, automotive-style trochoid oil pump ensures critical engine component long-term durability.
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.

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!

Counter Rotation
Improves efficiency, hull maneuverability and decreases driver fatigue.

Built-In Pilot Tube
Built-in pilot tube in the gear case eliminates the need to drill holes in your boat for installation.

Ultra Low 3 Star Carb Emissions
Cleanest technology available.
