Popular Outboard Motors from the Yamaha 4-stroke Line-Up

F115AETL The Proven Workhorse

The F115 engine beat off all competitors in recent RNLI trials and was

subsequently chosen to power the new Atlantic 85 fleet of fast

response rescue craft. Its blend of power, economy and durability put

it above the rest of its class.

• Excellent reliability proven in the field by the RNLI.

• Yamaha’s first ever EFI four-stroke remains virtually unchanged

since its launch over ten years ago.

• Long pulse tuned inlet tracts deliver fuel to this 16 valve DOHC

powerplant.

• Counter rotation FL model for twin engine set-ups eliminates any

torque steering reaction for straight line stability.

FEATURES & BENEFITS

Long Intake System (4-stroke)

Increases the air velocity into the engine for

added torque and performance.

Long-Life Piston/Piston Ring

The high-rigidity piston is made of a material that

ensures optimum thermal flow. The piston ring

has minimal friction resistance and good heat conductivity.

Long-span Mounting System

The large rubber mounts and the long vertical

length between the upper and lower mounts

serve to reduce vibration.

Loop-charged scavenging creates a circular flow

for efficient removal of exhaust gas and even dis-

tribution of the air-fuel mixture. The result is greater com-

bustion efficiency for higher power and better fuel economy.

Low Oil Pressure Warning (4-stroke)

When oil pressure falls below fixed pressure in

four-stroke, engine speed reduces and light and/

or buzzer alert the operator.
