The Yamaha 350Li is a full-featured seascooter engineered for serious underwater exploration. With 350 watts of motor power, three rotational speed gears, and automatic buoyancy control, it's built for divers who demand performance, precision, and reliability at depth.
The Yamaha 350Li delivers 350 watts of motor power — enough to propel you through currents, cover ground quickly, and maintain speed even when towing camera gear or dive equipment. With three rotational speed gears, you can dial in the perfect pace for cruising, exploring, or conserving battery for longer dives.
The 350Li's automatic buoyancy system is engineered for saltwater environments, adjusting trim dynamically as you descend and ascend. Ballast weights and glide fins come included in the box, allowing you to fine-tune buoyancy for your specific dive conditions. The result is a scooter that stays level without constant input — freeing your hands for navigation, photography, or simply enjoying the dive.
Powered by a 22.2V / 8Ah lithium-ion battery, the 350Li offers up to 75 minutes of runtime on a full charge under normal use. Li-ion technology delivers twice the cycle life of traditional lead-acid batteries, meaning fewer replacements and lower long-term cost. An LED battery status indicator keeps you informed at a glance, and the battery recharges in 4–6 hours.
Shift between three speed modes as you glide effortlessly through open water, conserving your energy for more bottom time. Rated to 40 metres and delivering up to 75 minutes of runtime, the 350Li lets you concentrate on the scenery — not your equipment. Whether you're exploring coral reefs, wrecks, or blue-water drop-offs, this is the seascooter that keeps pace with your curiosity.

Designed for saltwater, the 350Li's automatic buoyancy system adjusts trim in real time — so you can focus on navigation, photography, and the dive itself without constantly managing your scooter's attitude.
The Yamaha 350Li is depth-rated to 40 metres (130 feet), making it suitable for recreational diving, freediving, and technical dives within this range. It should not be used beyond this depth rating.
The Yamaha 350Li provides up to 75 minutes of runtime on a full charge under normal use. Actual runtime will vary depending on speed setting, water conditions, and load. Continuous high-speed use may reduce runtime to approximately 30 minutes. The battery takes 4–6 hours to fully recharge.
Yes. A GoPro mount is included in the box, allowing you to attach a standard GoPro or compatible action camera to the scooter. The camera itself is not included. This makes the 350Li a popular choice for underwater videography and photography.
The Yamaha 350Li features three rotational speed gears, allowing you to select the appropriate pace for your dive. Lower speeds conserve battery and provide gentle, controlled movement, whilst higher gears deliver maximum propulsion for covering distance or working against currents.
Yes, the Yamaha 350Li is suitable for both saltwater and freshwater environments — including the sea, lakes, and swimming pools. The automatic buoyancy system is optimised for saltwater use. After saltwater use, rinse the unit thoroughly with fresh water to protect the seals and extend the life of the scooter.
