Yamaha is known for creating high quality products, and this seascooter is no exception. It has some pretty cool features which you can read about below along with more important details.

Yamaha 350li Seascooter Review

The Yamaha seascooter 350li offers a great way to explore the underwater world. It has received positive ratings for its innovative design, durability and high performance. It is very powerful with a lot of torque for speed control and can be used by experienced divers and beginners. 

How fast is the Yamaha 350li Seascooter?

When it comes to seascooters, spead is almost always one of the first questions asked. The Yamaha 350li Seascooter can reach an underwater speed of 3.7 miles per hour. 

The 350li has three different speed gears that a rider can choose from. This is important because it allows riders to switch to lower speeds and save battery when needed. 

The 350li features a 22.2V Lithium battery that typically lasts for 75 minutes underwater. It usually takes around 4 to 6 hours for the seascooter to reach full charge. A really cool feature about the 350li is that it has an accurate battery level light that tells you how much battery is left. 

The battery is replaceable, and a new 22.2V lithium battery usually costs around $700.




The Yamaha 350li Seascooter weighs 19 pounds and has a length of 24 inches. Due to its weight and size, I would recommend only using the 350li if you are at least 13 years old and have experience swimming. 


The 350li has been complimented for its hull that is able to maintain buoyancy and balance by allowing water to enter and exit the seascooter while underwater. Once the seascooter leaves the water, the water is drained and the seascooter automatically floats. The high quality buoyancy is great because it allows the rider to enjoy the views around them instead of focusing on trying to balance. 

The 350li can reach depths of up to 130 feet, which is the deepest any Yamaha seascooter can go at the time of this writing. 

Camera mount

The 350li has a camera mount that is compatible with all go pro cameras. Other underwater cameras that have the same mount system as the go pro can also fit on the seascooter. 


Handlebars are also extremely important when evaluating a seascooter. After all, a riders hands will be on the handlebar the entire time while you are underwater, so it is important to have a comfortable handlebar. The 350li has been praised for having a comfortable handlebar and a convenient trigger system that allows for smooth handling. 

How much does the Yamaha 350li Seascooter cost?

At the time of this writing, the Yamaha 350li Seascooter costs $1,195. This places the Yamaha 350li Seascooter as one of the most expensive seascooter on the market.
