AMELIA ISLAND, Fla.--(Business Wire)--
Yamaha announced today the arrival of a new 250-horsepower
four-stroke outboard, internally called the F250B, which offers
digital electronic control and other upgrades designed to further
enhance efficiency, functionality and value.

   "The changes we've made in the F250 will increase the already
broad appeal of the outboard," said Phil Dyskow, Yamaha Marine Group
President. "At the same time, we have strengthened those
characteristics that contribute to Yamaha's legendary reliability."

   "When we introduced Command Link(R) digital electronic control on
the F350 last year, the response was so positive that we had to bring
the technology to the F250. Command Link alone will increase ease of
operation and provide new features for boaters and anglers."

   The F250 will use the very same Command Link control system
introduced for the F350 and F300 last year. The system has a number of
exclusive features not found on mechanical controls. It has no cables
and therefore provides smoother operation. In place of the mechanical
cable is an electrical wire attached to connectors, which allow simple
plug-and-play operation with the outboard(s) and peripheral devices.
Major benefits of the system include precise trolling control in 50
rpm increments, automatic engine synchronization and easy dual-station
fitment. The control unit itself comes in a variety of binnacle
configurations for single or multiple engine applications. New this
year is the Command Link 6X7 concealed side-mount control for single
outboard applications.

   The F250 design also incorporates improvements intended to
increase reliability and durability, including an upgraded corrosion
protection package. The F250 will share the same special powerhead
paint process used in the F350. The inside and outside of the
powerhead are both treated with an anti-corrosion paint using a
special electro-deposited process.
