DF250 Four Stroke
Those who want the best
low-end torque and highest possible speeds from their outboards have
stuck with two-stroke power. Until now, that is. When it comes to
performance, Suzuki's new family of kick-ass V-6 engines (200, 225 and
250 hp) stack up unashamedly against the best the two-strokes world has
to offer. You can't argue with 3.6-liter displacement - the largest of
any V-6 four-stroke. Additionally, a 2.29:1 gear ratio affords you the
luxury of turning a 16-inch prop, larger than comparable four-strokes
With a 55-degree block, these V-6s are smaller than the competition. The
proven offset drive shaft moves the engine farther forward on the
transom for better center of gravity and balance. Variable valve timing
on the DF250 provides incredible low- and midrange torque, which are
especially needed on bigger boats. Multistage induction features two
separate air intake pipes - one for low speed and one for high revs.
Suzuki builds an ignition coil into each spark-plug cap, resulting in
fewer parts and less electronic noise to interfere with navigation and
communications equipment. And so you'll never have a problem keeping
that equipment powered up, Suzuki mounts a 54-amp alternator (a full 32
amps at trolling speed) under the flywheel, where it no longer needs a
power-robbing belt drive and where the flywheel fins can help cool it,
Suzuki realized early on that its four-strokes ran so quietly, people
often turned the key to start them while the engine was already running.
Consequently, the company now has an electronic cutout to prevent the
starter motor from engaging when the outboard is running.
And finally, Suzuki's 32-bit computer boasts twice the power of other
outboards, providing better performance control.
