Whether you’re a seasoned boater or just starting out, having the right outboard motor can help ensure a safe and enjoyable experience on the water.

Understanding Outboard Motors

Outboard motors, typically used in saltwater boating, are external propulsion systems that power boats through water. They vary in size and power, usually ranging from 2 to 400 horsepower.

Types of Outboard Motors

  • Two-stroke outboards: While these are lighter and pack more power, they consume more fuel and emit more pollutants.
  • Four-stroke outboards: These are weightier with less power but are more fuel-efficient and eco-friendly.

Determining Power and Size

  • Displacement: The power potential of an outboard motor depends on its displacement, i.e., the cylinder volume. Measured in cubic centimeters (cc) or liters (L), a greater displacement denotes higher power.
  • Horsepower: The size relates to its horsepower, which signifies its peak power. The required motor size is influenced by the boat’s dimensions, weight, and anticipated speed.

Power Sources for Outboard Motors

  • Gasoline: Most common power source.
  • Diesel & Electric: Gaining popularity.
  • Alternative Fuels: Options like propane are available.

Shaft Length Matters

The shaft length, indicating the submersion depth in water, is crucial for optimal performance. Match the shaft length to your boat’s size, weight, and desired operational attributes.

Outboard motors are pivotal for saltwater enthusiasts. They offer varied sizes and power options, with power sources like gasoline, diesel, or electricity. Prioritize power, efficiency, and the shaft’s length when making your choice.

Factors to Consider When Selecting an Outboard Motor

Finding the perfect outboard motor for saltwater boating necessitates evaluating a multitude of aspects. Here’s a structured guide to ease your decision-making.

Boat Weight and Size

Typically, ensure at least one horsepower for every 100 pounds of boat weight. Avoid motors too small or large, as they can compromise safety and performance.

Performance and Power

  • Torque: The motor’s rotational force.
  • Thrust: The force it generates to propel the boat. For smoother sailing, especially in choppy waters, aim for a motor with high torque and thrust.

Fuel Efficiency

  • Impact: A motor’s fuel efficiency influences your trip’s range and cost.
  • Tip: Opt for motors with advanced fuel injection systems, like battery-less EFI, to enhance fuel efficiency.

Reliability and Corrosion Resistance

  • Saltwater’s Effect: It can erode outboard motors, demanding a corrosion-resistant design.
  • Materials: Look for stainless steel or other anti-corrosion components.
  • Support: Check the warranty and customer service of the manufacturer for peace of mind.


  • Range: Costs can vary from a couple of hundred to several thousand dollars.
  • Note: While higher-priced motors might pack more features, they might exceed what you actually need. Always balance cost with requirements.

Repower Options

  • For Existing Owners: If considering an upgrade, check if manufacturers have repower programs. These often present newer models with extended warranties and additional perks.
