If you’re in the market for a high-performance outboard engine, the Used Yamaha F250 250hp 4 Stroke Extra-Long Shaft EFI Outboard Engine offers a blend of power, efficiency, and reliability that boat enthusiasts and professional anglers alike will appreciate. Yamaha has built a reputation for producing some of the most durable and fuel-efficient marine engines, and the F250 is no exception.

Overview of the Yamaha F250 250hp Outboard

The Yamaha F250 is a four-stroke, 250-horsepower outboard engine designed for medium to large-sized boats. It combines advanced electronic fuel injection (EFI) with a four-stroke design, delivering exceptional fuel efficiency without compromising on power. The extra-long shaft makes this engine perfect for deep-V hulls or boats with transoms that require additional clearance from the water.

Key Features Include:

• Horsepower: 250 hp

• Engine Type: 4-Stroke

• Fuel System: Electronic Fuel Injection (EFI)

• Shaft Length: Extra-Long (XXL)

• Weight: Approximately 568 lbs (varies by configuration)

• Steering: Available in both hydraulic and cable steering setups

This engine is ideal for offshore fishing, cruising, and watersports where a balance of speed, torque, and durability is critical.

Benefits of Buying a Used Yamaha F250 EFI Engine

Purchasing a used Yamaha F250 can provide significant advantages:

1. Cost Savings: A used engine can save thousands compared to buying new, while still providing excellent performance.

2. Proven Reliability: Yamaha engines are known to last tens of thousands of hours when properly maintained.

3. High Resale Value: Yamaha outboards tend to retain value, making a used F250 a smart investment.

4. Fuel Efficiency: The EFI system ensures optimal fuel-air mixture for efficient combustion, saving money at the pump.

5. Power and Torque: Perfect for heavy boats, large pontoons, or watersport applications.

Understanding the Extra-Long Shaft

The extra-long shaft is a vital feature for boats with deep transoms or higher freeboard. Standard-length outboards may not provide sufficient propeller immersion in the water, leading to reduced performance and cavitation. The extra-long shaft ensures:

• Full propeller engagement for maximum thrust

• Improved acceleration and top speed

• Smooth handling in rough water conditions

Boaters who operate offshore or in areas with larger waves will find the extra-long shaft especially beneficial.

Yamaha EFI Technology

One of the standout features of the F250 is its Electronic Fuel Injection (EFI) system:

• Automatic Fuel Delivery: Adjusts fuel and air for optimal engine performance

• Better Cold Starts: Easier to start in chilly conditions compared to carbureted engines

• Lower Emissions: Meets modern environmental standards

• Reduced Maintenance: No carburetor cleaning or tuning needed

EFI makes the F250 not only powerful but also more environmentally friendly and cost-effective over its lifetime.

Maintenance Tips for a Used Yamaha F250

To ensure longevity and peak performance, maintain your used F250 properly:

1. Regular Oil Changes: Use Yamaha-recommended four-stroke motor oil every 100 hours or annually.

2. Inspect Propellers: Check for dings or damage that can affect efficiency.

3. Flush After Saltwater Use: Prevent corrosion by flushing with fresh water after each use.

4. Check Spark Plugs: Replace plugs as needed to ensure optimal combustion.

5. Monitor Fuel System: EFI systems benefit from clean fuel and regular fuel filter changes.

Proper maintenance can extend the life of your engine and maintain resale value.
