The Yamaha 500Li is the pinnacle of the professional dive series — delivering 500 watts of pure thrust and up to 90 minutes of runtime. Built for serious divers and underwater explorers who demand the best in class performance, depth capability, and reliability.
The 500Li features Yamaha's most powerful motor — 500 watts of continuous thrust capable of pushing you through currents and covering serious underwater distance. With a 3-speed gear system, you can adjust your speed to match your dive plan: cruise efficiently on lower gears for extended runtime, or unleash full power when you need to move fast. The result is a scooter that adapts to your ambition.
The Yamaha 500Li's self-filling ballast hull automatically achieves neutral buoyancy when submerged, eliminating the need for manual weight adjustments. Strategically placed drain holes allow water to enter and exit the ballast chamber freely, so the scooter balances itself at depth and expels water as soon as it surfaces. This means easier handling, better manoeuvrability, and less fatigue during long dives.
The 500Li's Li-Ion battery delivers up to 90 minutes of runtime on a single charge — far surpassing conventional lead-acid alternatives. Not only does lithium-ion technology provide longer dive sessions, it also charges faster (7–9 hours), weighs less, and lasts twice as long over the battery's total lifecycle. The removable design allows for external charging and quick battery replacement, making multi-dive days effortless.
Glide through the water at speeds up to 4.35 mph, conserving energy whilst covering greater distances. Rated to 40 metres and equipped with automatic buoyancy control, the 500Li lets you explore reefs, wrecks, and open water with confidence. Spend less time kicking and more time discovering what lies beneath.

The self-filling ballast hull achieves neutral buoyancy almost instantly underwater, then expels water automatically as you surface. No manual adjustments, no guesswork — just seamless transitions.
The Yamaha 500Li is depth-rated to 40 metres (130 feet), making it suitable for recreational diving, technical diving, and freediving. It is designed for both professional and recreational use. Always stay within your own diving certification limits and do not exceed the rated depth.
The Yamaha 500Li provides up to 90 minutes of runtime under normal use. Actual runtime will vary depending on speed setting, water conditions, load, and usage patterns. Continuous high-speed operation will reduce runtime. The Li-Ion battery takes 7–9 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 500Li ideal for underwater photography, videography, and capturing dive footage.
The Yamaha 500Li features a self-filling ballast hull that automatically achieves neutral buoyancy when submerged. Water freely enters and exits the ballast chamber through strategically placed drain holes, so the scooter balances itself at depth and expels water when you surface. This eliminates the need for manual ballast adjustments and improves handling.
The Yamaha 500Li is designed for both professional and recreational divers. The 3-speed gear system allows less experienced users to start on lower speeds for more controlled, gradual movement, then progress to higher speeds as confidence builds. Yamaha recommends users be aged 16 or over. No special licence or training is required to operate a seascooter.
