When it comes to choosing an electric outboard motor, one of the key decisions is finding the correct shaft length. The right shaft length ensures optimal motor performance, keeping your boat stable and maneuverable even in rough waters. But how do you choose the right length? In this article, we will explore the key factors that influence this choice and provide guidelines to determine the best option for your boat.

Shaft Length: Why It’s Important

The shaft length of an electric outboard motor directly impacts its efficiency and functionality. A shaft that is too short may not submerge enough in the water, reducing thrust and leaving the motor exposed to the waves. On the other hand, a shaft that is too long could be cumbersome and difficult to maneuver, especially in shallow waters. This is why it’s essential to find a balance between maneuverability and performance.

How to Calculate the Correct Shaft Length

To determine the ideal shaft length, you need to consider the height of your boat’s bow or transom. It is generally recommended to add at least 30 cm (12 inches) to the distance between the water's surface and the point where the motor will be mounted. This ensures that the propeller remains fully submerged, even in waves or choppy conditions.

Here is a simple formula to calculate the minimum shaft length:

• Measure the distance between the motor mount point and the water’s surface.
• Add 30 cm to this measurement to ensure the motor stays submerged at all times.
• For example, if the distance between the transom and the water’s surface is 50 cm, the motor shaft should be at least 80 cm.

Common Shaft Lengths for Electric Outboard Motors

The most common shaft lengths vary between 36" and 60", depending on the size and type of boat. Below are some general guidelines:

• Small boats (canoes, kayaks, inflatable boats): A 36-42 inch shaft is usually sufficient.
• Medium boats (small fishing boats, bass boats): Opt for a 42-48 inch shaft.
• Larger boats (offshore fishing boats, pontoon boats): You may need a 54-78 inch shaft to ensure the motor stays properly submerged.

Consider Water Conditions

The conditions in which you usually fish are also a factor to consider. If you fish in calm, shallow waters, a shorter shaft may be sufficient. However, if you often find yourself in rough waters or open seas, a longer shaft will provide greater stability and control.
