When choosing an electric motor for your boat, it's common to wonder how its thrust compares to traditional combustion engines measured in horsepower (HP).
This comparison isn’t always straightforward, as electric and internal combustion motors operate differently and are measured using different units. However, there are general equivalences that can help guide your evaluation.

How is the thrust of an electric motor measured?

The thrust of an electric motor, like those available on our Watersnake website, is typically measured in pounds (lbs). This unit indicates the force the motor can generate to push the boat through the water. For example, a motor with 30 lbs of thrust is less powerful than one with 80 lbs of thrust.

Converting thrust (lbs) to horsepower (HP)

To convert an electric motor’s thrust to horsepower, an approximate formula is used. On average, it's estimated that 72–75 lbs of thrust is roughly equivalent to 1 HP. However, keep in mind this conversion is not exact due to the differences in how the two types of motors operate.

How many horsepower is an electric motor with 80 lbs of thrust?

Using the approximate conversion, an electric motor with 80 lbs of thrust equals about 1.06 HP. This estimate is based on the indicative formula where 1 HP is equivalent to around 75 lbs of thrust:

Horsepower (HP) = Thrust (lbs) ÷ 75

Applying the formula:
80 lbs ÷ 75 ≈ 1.06 HP

Watersnake motors and their performance

On the Watersnake website, we offer a range of electric motors designed to meet a variety of needs. For example, the Watersnake Venom SXW model is ideal for smaller fishing boats and provides enough thrust for precise and quiet maneuvering. For larger boats or more demanding conditions, a motor like the Watersnake GEO-SPOT GPS 80LB 78" Shaft Electric Trolling Motor Bow Mount offers higher power, comparable to about 1.06 HP, ensuring optimal and long-lasting performance.

Advantages of Watersnake electric motors

Choosing a Watersnake electric motor offers numerous advantages over traditional combustion engines:

• Quiet operation: Electric motors are much quieter—ideal for fishing.

• Eco-friendly: They produce no emissions, making them a more environmentally friendly choice.

• Low maintenance: Fewer moving parts mean less maintenance compared to combustion engines.

• Ease of use: Easy to install and operate—great for both beginners and experienced users.
