Boosted Low Speed Torque, or BLAST, uses Honda’s patented spark advance system to propel the boat to plane in just seconds.

When you move the throttle quickly, BLAST is activated:

• The throttle body opens up
• The air-fuel ratio goes to a richer setting
• The ignition timing advances aggressively

This allows the engine to make more torque, or power.

“Hole Shot” is vastly improved, as more horsepower gets the hull up on plane quicker.

Honda’s Variable Valve Timing & Lift Electronic Control (VTEC ^® ) system provides power where and when you need it.

VTEC is the “replacement for displacement.”

• Outstanding performance without the inferior low rpm fuel efficiency of larger displacement competitors.
• Broader, flatter torque curve
• Smooth power delivery throughout the engine’s operating range.

How does VTEC work?

VTEC varies the lift and duration of the intake valves to deliver optimal performance at both low and high rpm, resulting in peak performance at all speeds.

VTEC uses two cam lobe profiles to operate the intake valves.

• The low-lift, short duration cam lobes (shown in red) provide strong torque at low rpm.
• At higher rpm, a synchronizing piston engages the third rocker arm on a high-lift cam (in blue). All three rocker arms are locked together. The intake valves are open for a longer period of time to produce more power.
• This results in a superior combination of power, torque and fuel efficiency.

Introducing Honda Marine’s new iST Intelligent Shift & Throttle

Introducing the new Honda Intelligent Shift and Throttle (iST). Superb control and easy installation are hallmarks of Honda’s new command and control system. iST provides all the features boaters are looking for, including:

• Control of up to 4 engines and 2 control stations
• Effortless shift and throttle control
• Fine tuning of throttle settings at any speed
• Enhanced docking and slow speed control
• User-programmable system defaults
• Simple, easy to understand user interface

Multi-Engine Applications

For multi-engine installations, the system provides one switch trim control on the throttle handle, trimming all engines simultaneously. Individual trim switches allow for fine tuning each engine’s trim position. The system also provides engine speed synchronization, and single handle control of all engines while synchronized.

Simple Installation

Honda has also made iST easy to install. No programming or special tools - just connect one communication cable between the engine and the helm mounted control head, and you’re done. Adding a second station can be done just as easily. Simply install the second control head and connect cable to the existing system.

• Plug and play, requires no programming or special tools to install
• Stylish modern binnacle control box
• Compact, under the cowl design
• Up to four engine installations
• Near effortless shifting under all conditions
• Intelligent engine RPM synchronization with one handle throttle control
• Master trim control on throttle handle, individual trim controls on head unit
• for dual engines, and auxiliary panel for triple and quads
• "Slow"" mode for increased throttle control while maneuvering at slow speeds, such as around the dock or a crowded marina
• "Trolling"" mode for incremental RPM adjustments at any speed
• Easy helm control transfer up to two stations

Honda’s 4-Front Corrosion Protection System fights off corrosion from harsh marine environments. This patented double-sealed, multi-layer paint process uses 4 different layers to protect the engine.

• The base is a corrosion-resistant Honda aluminum alloy, followed by a double-sealed treatment.
• An epoxy primer undercoat is applied.
• An acrylic resin metallic coating is baked on.
• A clear overcoat of acrylic finishes the process.

Honda engines have several other features designed to help protect them from the harsh marine environment:

• Sacrificial anodes protect the engine from galvanic corrosion.
• All fasteners and hardware are either stainless steel or a specially treated Dacro material.
• All wiring connectors are sealed to prevent water intrusion.
• Fresh water flush ports on select models allow you to flush the engine with a garden hose.

There's always plenty of electric power with Honda's "on demand" alternator. It gives you more charging power when you need it.

Our belt-driven system helps batteries to stay charged and keeps equipment going all day long.

In fact, the BF225’s "On Demand" 90 amp belt-driven alternator puts out the highest amount of amps in the outboard market.

Honda's alternator provides more electric power than the competition. For example, the BF200/225, shown in blue, has significantly more amps available than competitive four-stroke motors

Alternators, by the numbers

Honda advertises the real amps that you would see in real use. Some outboard manufacturers only advertise their total alternator output, measured at cool temperatures. This can be somewhat misleading

• Honda measures alternator output at normal operating temperatures. Most other manufacturers measure using a cool alternator, which produces more amps
• Honda advertises total amps and “charging amps.” Charging amps are the total amps minus the ignition’s requirements. For example, say an engine produces 27 amps in total. The ignition uses 5 amps, leaving 22 charging amps available to power accessories

Compare for yourself, and you’ll see: apples to apples, Honda motors give you the power you need.
