Honda's
revolutionary Boosted Low Speed Torque (BLAST™) system is now featured in every
model from the compact BF40 right through to the class-leading BF225.
Making its
debut in the BF75/90 in 2006, BLAST was developed to improve acceleration at
lower speeds. Activated by sharp throttle movement, the air/fuel ratio ignition
timing control technology results in powerful hole shot performance to get
boats on the plane quicker.
Honda
Australia assistant marine service manager Stephen Harvey said the patented
BLAST technology was the global benchmark for four-stroke outboard engine
design.
"In a
nutshell, BLAST makes available the greatest amount of torque at the precise
moment it's required," Mr Harvey said.
"The
engine's Electronic Command Unit (ECU) determines throttle opening during
acceleration and advances the ignition timing to develop more horsepower at low
revs.
"A quick
movement of the throttle control lever activates BLAST, aggressively advancing
the ignition curve, while upon slow advancement of the throttle a mild ignition
spark advance curve is initiated and the engine operates as normal."
During
acceleration, the air/fuel ratio goes to a richer setting. At that point, the
ECU – receiving information from the throttle sensor and other engine sensors –
determines the best spark advance by tracing the ignition timing for best
air/fuel ratio.
"The boost
in horsepower and torque at low revs contributes to very strong acceleration
from 0-50m to get boats on the plane very quickly, something which was
traditionally considered a weak point of four-stroke outboards," Mr Harvey
said.
"Combining
incredible out-of-the-hole performance with all the benefits of Honda's
advanced four-stroke technology, BLAST has changed attitudes towards
four-stroke outboards the world over."
BLAST is available in Honda's BF40, BF50, BF60,
BF75, BF90, BF115, BF135, BF150, BF175, BF200 and BF225.

Incorporating unique attributes such as BLAST, ECOmo and
VTEC, along with a five-year warranty, Honda's technologically-advanced
four-stroke outboard engines run quieter, offer greater fuel economy,
burn
cleaner and are just plain better for the environment... at the same
time
delivering superior power and unmatched reliability. Honda –
four-strokes of
genius.
