FEATURES & BENEFITS

Hard-Chrome-Plated Water Pump

Plating the inside of the water pump with hard-

chrome helps to prevent wear in muddy water

and maintain high performance.

High Output Alternator

Provides ample charging, even at slower speeds.

High-Precision Intake and Exhaust Tuning

Extremely modified intake and exhaust passage

increases combustion efficiency for maximum

performance and better economy.

HPDI: High Pressure Direct Injection

Delivers fuel to cylinders at the high pressure 7

MPa to deliver optimum performance.

In-Bank Exhaust (4-stroke)

The intake tracks enter the engine heads from

the outward side, between the cylinder bank like

two-stroke V6 engine. The system is Yamaha’s exclusive

technology that enhances performance while slashing down

the weight and the size.

Fail-Safe System

Keeps engine running if any of the sensors

failed.

Flywheel Damper

A built-in rubber damper to reduce any engine

vibration for a smooth, pleasant boating experi-

ence.

F-N-R Gear Shift

The smooth forward-neutral-reverse gear shift is

easy to operate, providing excellent maneuver-

ability.

Forged Piston (4-stroke)

Exhibits higher tensile strength against fatigue,

and high temperatures. It is lightweight, and has

excellent anti-wear and anti-seizing quality.

Freshwater Flushing Device

The engine does not need to be running to effec-

tively flush the unit. By regularly flushing the en-

gine, long term corrosion durability is assured.

FEATURES & BENEFITS

Speedometer Pitot Tube

The lower unit is equipped with a pickup sensor,

so speedometer operation does not require a

separate pickup.

Splined Propeller Shaft

Increases propeller strength to prevent damage

if propeller strikes an object and eliminates the

need for shear pin replacement.

Spiny Outer Cylinder Sleeve

Keeps roundness of the cylinder for higher cool-

ing efficiency and reduced oil consumption.

Stainless Steel Propeller

A durable, anti-corrosive propeller built for supe-

rior performance, excellent anti-cavitation and

long life.

Steering Friction Adjustment

Steering friction can be adjusted to be heavier at

lower speeds and lighter at higher speeds, for

more steering.

Sturdy Gears and Gear Case

The gears and the gear case, built tough and du-

rable, can withstand collisions with rocks and

other objects.

Shallow Water Drive

The outboard can be set at a tilt angle, preventing

it from hitting the bottom when operating in shal-

low water.

Simple Operation Steering Friction

Adjusts steering tension at the touch of a finger-

tip.

Single Belt Drive System (4-stroke)

Uses fewer moving parts and is simple in design

for long term durability.

Single Throttle Body (4-stroke)

A simple and lightweight design for greater reli-

ability and quick and easy adjustment if ever

needed.

Single Unit PTT

Power trim and tilt cylinders are combined into a

single unit for compactness, high performance,

good response and smooth, quiet operation.

Special Aluminum Alloy: YDC-30

Developed for major exterior parts of the motors

after years of research and testing, YDC-30 of-

fers truly superior anti-corrosion properties.
