What is an outboard motor?

An outboard motor is a powerful piece of machinery used to propel a boat through the water. It is typically mounted on the boat's transom and consists of a gasoline-powered engine, a propeller, and a gearbox. Outboard motors come in various sizes, from small ones suitable for small boats to larger ones that can power bigger vessels. As a fisherman, an outboard motor is essential for quickly and efficiently getting to your favorite fishing spots quickly and efficiently. With the right outboard motor, you can cover more water and increase your chances of catching more fish.

Choosing the right outboard motor for your fishing style

Choosing the right outboard motor for your fishing style is crucial for achieving success on the water. There are a few factors to consider when selecting an outboard motor, such as:

  • the size and weight of your boat
  • the type of water you will be fishing in
  • your preferred fishing style.

 If you're a bass fisherman who enjoys casting, a smaller outboard motor with a higher thrust may be the best option. On the other hand, if you're a walleye fisherman who prefers trolling, a larger outboard motor with a lower thrust may be more suitable. It's also important to consider fuel efficiency and reliability when choosing an outboard motor. This can save you money and prevent frustration on the water. By taking the time to research and choose the right outboard motor for your fishing style, you can maximize your time and catch more fish on your next outing.

Two stroke or four stroke?

When it comes to outboard motors, both two-stroke and four-stroke engines have their advantages and disadvantages. Two-stroke engines are typically lighter, simpler, and less expensive than four strokes. They also provide more power for their size and are easier to repair. However, two strokes tend to be louder, less fuel-efficient, and produce more emissions.

On the other hand, four-stroke engines are quieter, more fuel-efficient, and produce fewer emissions than two-stroke engines. They also tend to be more expensive and heavier but offer smoother operations and require less maintenance.

Choosing between a two-stroke and four-stroke outboard motor depends on your specific needs and preferences. A two-stroke engine may be the way to go if you prioritize power and simplicity. However, four strokes may be a better choice if you value fuel economy and environmental friendliness. Be sure to consider all factors before making your decision.

The advantages of using an outboard motor for fishing

  • Increased speed and mobility, allowing you to cover more water and reach fishing spots more quickly.
  • Ability to fish in different types of water, from shallow flats to deep offshore waters.
  • Conservation of energy, saving time and effort when reaching fishing spots.
  • The potential to catch more fish due to increased mobility and access to different fishing spots.
  • Added safety features such as backup engines and power tilt.
  • Ability to use the motor for recreational activities such as water skiing or cruising.
  • Flexibility to adjust the motor's speed to accommodate different fishing techniques, such as trolling or casting.
  • Improved maneuverability allows you to navigate obstacles or adjust quickly to changing water conditions.
  • Reduced physical strain and fatigue, allowing you to fish for longer periods without experiencing exhaustion.

Tips to keep your outboard motor running smoothly on the water

Perform regular maintenance:

Regular maintenance, such as oil changes, filter replacements, and spark plug replacements, can help prevent breakdowns and prolong the life of your outboard motor.

Use high-quality fuel and oil:

High-quality fuel and oil can help prevent engine damage and ensure optimal performance.

Check the water pump:

The water pump helps to cool the engine by circulating water through the system. It's important to check the water pump regularly to ensure it's functioning correctly.

Monitor the temperature gauge:

Monitoring the temperature gauge can help you identify overheating issues before they become serious. If the temperature gauge indicates the engine is running hot, you should reduce speed or shut down the engine and check for any potential issues.

Keep the propeller in good condition:

A damaged or worn propeller can reduce performance and increase fuel consumption. Check the propeller regularly and replace it if necessary.

Keep the fuel tank clean:

Dirt and debris can build up in the fuel tank over time, leading to clogs in the fuel system. It's important to clean the fuel tank regularly to prevent this.

Be aware of your surroundings:

Be aware of your surroundings and avoid running the motor in shallow or rocky waters, which can damage the propeller or motor.

By following these tips, you can help ensure that your outboard motor runs smoothly and reliably on the water, allowing you to enjoy your time without any unexpected breakdowns or issues.


Outboard motors are essential to any boat, especially for those who enjoy fishing and water sports. Choosing the right type of outboard motor for your needs can make all the difference in performance, fuel efficiency, and cost-effectiveness. Whether you opt for a two-stroke or four stroke motors or even an electric motor, keeping your motor well-maintained to ensure it runs smoothly and reliably on the water is important. 

 By following the tips and guidelines outlined in this blog, you can help ensure that your outboard motor lasts for many seasons of fun on the water, allowing you to enjoy your favorite activities without any unexpected setbacks or breakdowns.
