Yamaha F175 In-Line 4 – 20″ Shaft, 2019 Model – Reliable Power

The Yamaha F175 In-Line 4 – 20″ Shaft, 2019 Model is a high-performance outboard motor designed for boaters seeking reliability, efficiency, and smooth power delivery. Engineered for both recreational and light commercial use, it provides an ideal balance between fuel economy, durability, and versatility.

What It Is

This model is a 4-stroke, 16-valve DOHC in-line 4-cylinder engine with a displacement of 2.8 liters (2785 cc). Its bore and stroke measure 96 x 96.2 mm, producing 175 horsepower at 5500 RPM. The 20″ shaft length is compatible with medium transom boats, delivering optimal thrust and smooth handling. With a dry weight of approximately 480 lbs, it is lightweight for its class, improving boat performance and fuel efficiency.

How It Works

The F175 features Yamaha’s Electronic Fuel Injection (EFI) system, ensuring precise fuel delivery for optimal combustion efficiency. It also has a TotalTilt™ system for easy motor tilting, which is especially useful in shallow waters. The motor includes a 50-amp alternator to support onboard electronics and ensures consistent power output even under demanding conditions. Its wet sump lubrication system guarantees reliable oil circulation for long-term durability.

Benefits and Advantages

• Fuel Efficiency: The EFI system optimizes fuel consumption, allowing longer trips without frequent refueling.

• Reliability: Yamaha’s engineering ensures the motor withstands marine environments, saltwater, and long-term usage.

• Lightweight & Compact: Enhances overall boat speed, handling, and efficiency.

• Versatility: Compatible with both mechanical and digital control systems, adaptable to various boats and user preferences.

Safety and Responsible Usage Considerations

Safe operation is essential. Always follow local boating regulations and manufacturer safety guidelines. Regular inspections of the propeller, fuel system, and electrical components reduce the risk of malfunction. Avoid exceeding the recommended load capacity to maintain stability and ensure safe performance.

Longevity and Maintenance Tips

Routine maintenance extends engine life. Recommended tasks include changing engine oil and filters, inspecting fuel lines, and cleaning the cooling system. Using Yamaha-approved fuel additives prevents carbon buildup, maintaining smooth operation. Proper winterization, such as flushing with fresh water and storing in a dry location, prevents corrosion during the off-season.
