Yamaha Seawing II Underwater Seascooter – Ex Demo

Original price was: £1,149.99.Current price is: £700.00.

The Yamaha Seawing II is a twin-motor underwater seascooter built for divers and snorkellers who want real pace without a fight. Two motors drive it to 5 mph (8.0 km/h) in high gear, with a two-speed rotational switch letting you drop back to a steady 4.3 mph cruise when you would rather stretch the charge. A 14.8V 10Ah lithium-ion pack sits behind an OLED display that keeps speed, gear, and battery level in view at a glance, and the neutrally buoyant hull holds its trim in saltwater so you steer rather than wrestle. Rated to 100 ft (30 m) and fitted with a GoPro-compatible camera mount, the Seawing II turns every dive into something worth watching back. This unit is Carbon/Red, supplied with a new battery, and comes with a 1-year warranty.

Two Motors. Two Gears. One Serious Machine.

The Yamaha Seawing II pairs a twin-motor drivetrain with a two-speed rotational switch, pulling you through the water at up to 5 mph while an OLED display keeps speed, gear, and battery level exactly where you need them.

Twin Motors, Genuine Pace

Twin Motors, Genuine Pace

Two motors work together to drive the Seawing II to 5 mph (8.0 km/h) in high gear, quick enough to cover ground on a drift or close the gap on the rest of the group. Ease back to the low setting at 4.3 mph (6.9 km/h) for a relaxed cruise that goes easier on the battery. One twist of the rotational switch and the Seawing II changes character.

Everything You Need on One Screen

Everything You Need on One Screen

The built-in OLED display puts your current speed, selected gear, and remaining battery level directly in front of you, so you always know exactly how much dive you have left. No guesswork, no surfacing early to check. Just clear information where it matters, at depth, in real time.

Frequently Asked Questions

The Seawing II reaches 5 mph (8.0 km/h) in high gear and 4.3 mph (6.9 km/h) in low gear.

Actual speed will vary with current, depth, and how much kit you are carrying.

The Seawing II runs for up to 40 minutes per charge on the 14.8V, 10Ah (148 Wh) lithium-ion battery under normal use, or up to 30 minutes if run continuously without stopping. Actual runtime will vary with gear setting, depth, and water conditions. A full recharge takes approximately 3 hours using the supplied charger.
