Understanding the Mercury 50 HP 4 Stroke Bigfoot Engine

The Mercury 50 HP 4 stroke Bigfoot is a popular choice among boaters for its balance of

power, fuel efficiency, and durability. Unlike two-stroke engines, the four-stroke design

offers quieter operation and lower emissions, making it environmentally friendlier and

more economical over time.

What Makes the Bigfoot Model Unique?

The “Bigfoot” designation refers to the longer shaft length of this outboard motor,

typically around 20 inches. This design allows the propeller to sit deeper in the water,

providing better performance in boats with higher transoms or those used in shallow,

debris-filled waters. It’s particularly favored by fishermen and recreational boaters who

venture into rivers, lakes, and coastal waters where water conditions vary.

Key Features of the Mercury 50 HP 4 Stroke

**Fuel Efficiency:** The four-stroke engine consumes less fuel compared to two-

stroke counterparts, making longer trips more affordable.

**Durability:** Mercury’s engineering ensures that the 50 HP Bigfoot can withstand

tough boating conditions with minimal wear.

**Smooth Operation:** Reduced vibrations and noise contribute to a more

comfortable ride.

**Easy Maintenance:** Designed with user-friendly access points for routine checks

and servicing.

Getting Started with Your Mercury 50 HP 4 Stroke Bigfoot

Manual

If you’re new to this engine or simply want to ensure proper use, the manual is your go-to

source for step-by-step instructions. From initial setup to everyday operation, it covers all

the fundamental procedures.

Initial Setup and Pre-Use Checks

Before you hit the water, it's crucial to perform the recommended pre-start inspections as

outlined in the manual. This includes:

Checking the oil level and quality.

Inspecting the fuel lines for cracks or leaks.

Ensuring the propeller is free of damage and debris.

Verifying the cooling system is functioning properly.

Testing the throttle and shift controls for smooth operation.

Performing these checks regularly helps prevent breakdowns and extends the life of your

engine.

Starting and Operating Tips

Starting a 4-stroke outboard is straightforward, but the manual provides helpful tips to

avoid common pitfalls:

Always prime the fuel system before starting.

Use a choke only during cold starts.

Gradually increase throttle to avoid sudden strain on the engine.

Monitor the engine’s temperature and oil pressure gauges closely during operation.

Following these guidelines ensures optimal engine performance and reduces the risk of

damage.

Maintenance Essentials for Longevity

Routine maintenance is the backbone of keeping your Mercury 50 HP 4 stroke Bigfoot

running smoothly. The manual emphasizes a maintenance schedule that involves regular

checks and replacements.

Oil Changes and Lubrication

Changing the engine oil and oil filter at recommended intervals is critical. Mercury

typically advises an initial oil change after the first 10 hours of use, then every 100 hours

or annually thereafter. Using the correct grade of oil, as specified in the manual, helps

maintain engine efficiency and prevent wear.

Cooling System Care

The cooling system prevents the engine from overheating. Regularly inspect the water

pump impeller and replace it if signs of wear or damage are present. The manual offers

detailed instructions on how to access and service this component.

Fuel System Maintenance

Keeping the fuel system clean is vital for preventing clogs and ensuring smooth engine

operation. Use high-quality fuel and consider adding fuel stabilizers, especially if the

engine will be stored for an extended period. The manual also guides you through

inspecting and replacing fuel filters as needed.

Troubleshooting Common Issues

Even the most reliable engines encounter problems occasionally. The Mercury 50 HP 4

stroke Bigfoot manual includes a troubleshooting section that can save you time and

money by helping you identify and resolve issues early.

Engine Won’t Start

This is one of the most common problems boaters face. The manual suggests checking:

Battery charge and connections.

Fuel supply and primer bulb condition.

Spark plugs for fouling or damage.

Kill switch position.

Often, simple fixes like replacing a spark plug or reconnecting a loose wire can get you

back on the water quickly.

Overheating

If your engine overheats, it’s essential to stop immediately to prevent damage. Check for:

Blockages in the water intake.

Worn or damaged impeller.

Low coolant flow.

The manual provides a systematic approach to diagnosing and fixing cooling issues.

Optimizing Performance and Fuel Economy

Beyond basic operation, the manual offers tips on how to maximize your Mercury 50 HP 4

stroke Bigfoot’s performance.

Proper Break-In Procedures

When your engine is new, following the break-in procedures is crucial. This involves

running the engine at varying speeds for the first 10 hours to allow components to seat

properly, which improves longevity.

Propeller Selection

Choosing the right propeller can significantly affect acceleration, top speed, and fuel

consumption. The manual advises consulting a propeller chart or a Mercury dealer to pick

the best fit based on your boat's size and intended use.

Regular Inspections for Preventive Care

Frequent inspections allow you to catch minor issues before they escalate. Keep an eye on

belts, hoses, and electrical connections, and adhere to the maintenance schedule in the

manual.
