Yamaha F175 DEC 175HP Four-Stroke – Integrated Hydraulic Steering

The Yamaha F175 DEC combines the performance of Yamaha's proven 2.8-litre four-cylinder engine with the smooth operation of Digital Electronic Controls (DEC) and the convenience of factory-integrated hydraulic steering.

Delivering 175HP, the F175 offers excellent acceleration, strong mid-range performance and impressive fuel efficiency, making it an ideal choice for offshore fishing boats, hardtops and recreational vessels.

With its modern cowling design, electronic throttle and shift, and integrated steering cylinder, the F175 DEC provides a clean, streamlined installation without sacrificing performance or reliability.

Whether you're repowering an existing boat or fitting out a new vessel, the Yamaha F175 DEC offers an excellent balance of power, technology and everyday usability.

Key Features

Digital Electronic Control (DEC)

Yamaha's Digital Electronic Control system replaces traditional mechanical throttle and shift cables with electronic controls.

This provides:

• Smooth, precise gear engagement

• Responsive throttle operation

• Effortless low-speed manoeuvring

• Reduced mechanical control cable maintenance

• A cleaner, more modern helm installation

The electronic throttle system provides excellent control whether you're navigating a marina, crossing a bar or heading offshore.

Factory-Integrated Hydraulic Steering

The F175 DEC features Yamaha's Integrated Hydraulic Steering (IHS) system.

Rather than using an externally mounted hydraulic steering cylinder, Yamaha incorporates the cylinder directly into the engine's transom bracket.

Benefits include:

• Cleaner transom installation

• Reduced exposure of steering components to the elements

• More space around the engine well

• Smooth, precise hydraulic steering

• Factory-engineered integration

This is conventional hydraulic steering, not electro-hydraulic steering.

The integrated cylinder connects to a conventional hydraulic helm and hydraulic hoses, which are purchased separately unless included in a fitted package.

Powerful 2.8-Litre Four-Cylinder Engine

At the heart of the F175 is Yamaha's 2785cc, 16-valve DOHC four-cylinder engine.

This proven engine delivers strong acceleration and responsive mid-range torque, making it particularly well suited to heavier fishing boats carrying passengers, fuel and equipment.

Its inline-four configuration provides an excellent combination of performance, reliability and weight.

Electronic Fuel Injection (EFI)

Yamaha's electronic fuel injection system precisely manages fuel delivery for smooth acceleration, reliable starting and efficient operation.

50-Amp High-Output Alternator

The F175 features a 50-amp alternator, delivering excellent charging performance for modern boating applications.

Yamaha specifies an output of approximately 22 amps at just 600 RPM, helping maintain battery charge when operating at low engine speeds.

This is particularly useful for boats running fishfinders, chartplotters, VHF radios and other onboard electronics.

TotalTilt™ with Integrated Tilt Limiter

The F175 DEC includes Yamaha's TotalTilt system.

A double press of the trim/tilt switch automatically raises or lowers the outboard, making engine positioning easier when launching, retrieving or storing your boat.

The integrated tilt limiter allows the maximum tilt position to be set, helping prevent the cowling from contacting bait boards or other transom-mounted equipment.

Variable Trolling Control

Yamaha's Variable Trolling Control allows engine speed to be adjusted between approximately 650 and 900 RPM in 50 RPM increments.

This provides greater control when trolling lures or fishing at low speeds.

Yamaha Shift Dampener System (SDS)

When fitted with a compatible Yamaha SDS propeller, the F175 benefits from quieter, smoother gear engagement with reduced vibration.
