The Nautica Marine 250 Seascooter is a single-speed underwater scooter developed for recreational swimming, snorkeling and scuba use by qualified divers. It delivers controlled propulsion up to 2.5 mph (4 km/h) and carries a product depth rating of 100 ft (30 m).
Its rechargeable 12V, 12Ah sealed lead-acid battery provides up to 120 minutes under normal, intermittent use. For shoppers comparing continuous operation, the exact manual specifies up to 45 minutes when the motor is operated without stopping. Charging a fully discharged battery takes approximately five to seven hours.
An adjustable buoyancy chamber can be kept empty for positive buoyancy during swimming and snorkeling or carefully adjusted toward neutral buoyancy for diving. The Marine 250 must never be adjusted to become negatively buoyant. Its integrated camera mount supports compatible sports cameras, although the camera and mounting screw are not included.
Choose this model when longer normal-use runtime and straightforward single-speed operation matter more than low carrying weight or multiple speed settings.
Extended Normal-Use Runtime
The 12V/12Ah battery delivers up to 120 minutes under normal, intermittent use, allowing repeated bursts of propulsion throughout a swimming, snorkeling or recreational dive session. Continuous motor operation is rated separately at up to 45 minutes.
Simple Single-Speed Propulsion
The Marine 250 uses one propulsion speed reaching up to 2.5 mph (4 km/h). Its straightforward controls suit buyers who prefer consistent thrust without managing multiple gears while in the water.
Adjustable Buoyancy Control
Keep the chamber empty for positive buoyancy during swimming and snorkeling. Qualified divers can adjust the chamber toward neutral buoyancy following the manual. The unit must never be configured for negative buoyancy.
100-Foot Product Depth Rating
The Marine 250 is rated to 100 ft (30 m). This is the unit’s maximum advised product depth, not permission or a recommendation for an unqualified person to descend to that depth.
Integrated Sports-Camera Mount
An integrated mount supports compatible sports-camera systems so users can configure their own underwater recording setup. The camera, waterproof housing and required mounting screw must be purchased separately.
Protective Rubberized Handling
The Marine 250 combines rubber-covered handles with a covered propulsion area. Its complete 17.8 lb weight should be considered when carrying, lifting or lowering the unit from a dock or boat.

Charging and Battery Care
- Remove the battery from the seascooter before charging.
- Charge in a dry, well-ventilated area away from children, water, flames, sparks and other ignition sources.
- Charge a fully discharged battery for approximately 5–7 hours.
- After charging, allow the battery to stand for at least 30 minutes before installation.
- Recharge within 24 hours after use.
- Recharge at least every three months during extended storage.
- Use only the supplied charger and correct original replacement battery.
Water and Seal Care
- Rinse the seascooter with fresh water immediately after use.
- Allow it to dry before storage.
- Keep the battery housing dry.
- Keep sand and grit away from sealing surfaces.
- Follow the manual when lubricating seals and the vent O-ring.
Buoyancy
- Keep the buoyancy chamber empty for swimming and snorkeling.
- For diving, adjust only toward neutral buoyancy.
- Never adjust the unit for negative buoyancy.
- The unit has less buoyancy and may sink in freshwater, lakes or pools.
Storage
- Remove the battery immediately after use.
- Never store the battery inside the seascooter.
- Store the seascooter vertically to avoid nozzle deformation.
- Store the battery separately in a ventilated area away from heat and ignition sources.
Age and Operating Limits
- Not for operators under 16.
- Scuba use is limited to qualified divers.
- Never use the unit as a life-saving device or buoyancy aid.
- Do not exceed the 100 ft/30 m product depth rating.
- Maintain enough battery capacity to return without relying on the seascooter.
Air Travel
The battery calculates to 144Wh, but it is sealed lead-acid—not lithium-ion. FAA’s portable wet-nonspillable exception generally requires no more than 12V and 100Wh. This battery exceeds that 100Wh threshold, and its exact transport classification is not published on the product page.
Do not promise passenger-airline acceptance. Contact the airline and battery manufacturer before travel and obtain the applicable battery specification or safety data sheet. FAA battery guidance
