Yamaha Outboard Weight Chart (+Power/Weight Ratio)

We have put together a comprehensive weight chart for all current Yamaha outboard models, making it easier than ever to compare the different power and shaft options.

Dry weight refers to the total weight of the motor without any fluids, such as engine oil, or gear oil. The power-to-weight ratio is represented as prop shaft horsepower per kilogram (hp/kg). Generally, a higher value is more desirable, as it indicates better performance.

Use the search box to quickly find the model you’re after. You can also sort it to find the best (and the worst) power-to-weight models. Let’s dive in!

Why Is Outboard Weight Important?

Knowing the weight of an outboard motor before purchasing it is crucial for several reasons:

Boat performance: The weight of an outboard motor can significantly impact the overall performance of your boat. A heavier motor may cause the stern to sit lower in the water, affecting the boat’s balance, handling, and speed. Conversely, a lighter motor may provide better fuel efficiency and faster acceleration.

Capacity limitations: Every boat has a specified weight capacity, including the maximum allowable weight for an outboard motor. Installing a motor that exceeds the recommended weight can lead to poor performance, potential damage to the boat’s structure, and even compromise the safety of the passengers on board.

Fuel efficiency: A lighter outboard motor typically consumes less fuel, which translates to lower operating costs and a reduced environmental impact. By considering the weight of an outboard motor, you can optimize fuel efficiency and save money in the long run.

Ease of installation and maintenance: Heavier outboard motors can be more challenging to install and maintain, as they may require additional equipment, such as a hoist or specialized tools, to safely handle their weight. A lighter motor is generally easier to manage and can simplify the installation and maintenance process.

Transportation and storage: The weight of an outboard motor can affect how easy it is to transport and store. A lighter motor will be more manageable when it comes to moving the motor between locations or storing it during the off-season.
