What size electric boat motor do I need?

Choosing the right size electric boat motor can make all the difference in your on-water experience. There are a few factors you need to consider in order to determine the size of your motor, such as the weight of your boat when it’s fully loaded. A good rule of thumb is to get 1HP of thrust for every 25-40 pounds of weight on your boat.

So, for example, if you have a boat that weighs around 800 pounds, it would require an engine with at least 20-32HP. It’s important to note that this is just a general guideline and the specific requirements for your boat may vary based on other factors such as wind, currents, and wave conditions.

Another thing to consider is the type of water you’ll be boating on. If you’ll be on a lake or river with calm conditions, a smaller motor may be sufficient. However, if you plan on boating on larger bodies of water or in more challenging conditions, a larger motor may be necessary to provide enough power and speed.

Ultimately, the size of your electric boat motor will have a big impact on your boating experience, so it’s important to carefully consider your needs and the specific requirements of your boat before making a final decision.
