The Nautica Marlin Seascooter is a compact Recreational Series underwater scooter designed for children ages 8 and older with adult supervision. It is intended for pool play, swimming and snorkeling in a pool or calm water close to shore. The single-speed propulsion system reaches up to 1 mph/1.6 km/h, providing a controlled pace for its manufacturer-listed use.

Its removable 12V 4.5Ah rechargeable lead-acid battery provides up to 60 minutes with normal intermittent use. The exact manual separately lists up to 35 minutes of continuous operation, while a fully discharged battery requires approximately five to six hours to recharge. The complete unit weighs 7.7 lb/3.5 kg including the battery and is depth-rated to 10 ft/3 m.

The Marlin includes a protective grille, master switch and trigger-release shutoff. It must be used with an approved personal flotation device, where the child remains within their depth and under adult supervision. This is not a life-saving device or buoyancy aid, and it must not be used in the open sea.

Designed for Supervised Ages 8+ Use

The Nautica Marlin is manufacturer-listed for children ages 8 and older with adult supervision. Its manual requires use only where the child remains within their depth and wears an approved personal flotation device. The Marlin is not a life-saving device, swimming aid or substitute for direct adult supervision.

Controlled Single-Speed Propulsion

The Marlin uses one speed setting with a manufacturer-rated maximum of up to 1 mph/1.6 km/h. Its master switch and on/off trigger provide straightforward operation. Releasing the trigger stops the propeller, while the protective grille helps separate the user from the enclosed propulsion assembly.

Two Clearly Defined Runtime Ratings

The manual distinguishes between up to 60 minutes with normal intermittent use and up to 35 minutes of continuous operation. This distinction gives buyers a more accurate expectation than describing the full 60 minutes as continuous runtime. Battery condition, water conditions and operating pattern can affect real session length.

Removable 12V Lead-Acid Battery

A removable 12V 4.5Ah rechargeable lead-acid battery powers the Marlin. A fully discharged battery requires approximately five to six hours to recharge. The battery must be removed for charging and storage, and the exact manual assigns battery charging and safety responsibility to an adult.

Compact Exact-Model Dimensions

The complete Marlin measures 10.5 × 10.5 × 13.3 inches and weighs 7.7 lb/3.5 kg with its battery installed. Without the battery, the unit weighs 4 lb/1.8 kg. Its compact Recreational Series format distinguishes it from the larger and faster Skipper and Navigator models.

Pool and Calm-Water Operating Limits

The Marlin is intended for pool use or calm water close to shore and is equipment-rated to 10 ft/3 m. The manual prohibits open-sea use. It also warns that water type and conditions affect buoyancy, so the unit should never be released or left unattended in the water.

What’s Included with the Nautica Marlin Seascooter?

The manufacturer’s package list includes:

  • 1 × Nautica Marlin Seascooter
  • 1 × 12V 4.5Ah rechargeable lead-acid battery
  • 1 × battery charger
  • 1 × Navigator/Skipper/Marlin user manual

A camera, camera mount, spare battery, carry bag and separate replacement charger are not listed as additional included items.

Before First Use

Operating the Marlin

  • Place the Marlin in the water.
  • Move the master switch to the On position.
  • Pull and hold the on/off trigger to start the propeller.
  • Release the trigger to stop the propeller.
  • Move the master switch to Off whenever the unit is out of the water.
  • Remove the battery whenever the Marlin is not being used.

Charging and Battery Care

Battery charging and safety must be handled by an adult.

  • Switch the Marlin off and ensure it is out of the water and completely dry.
  • Open the nose cone and allow two minutes for accumulated gases to dissipate.
  • Disconnect and remove the battery before charging.
  • Place the battery on a level surface in a dry, well-ventilated area away from children, flames, sparks and other ignition sources.
  • Connect the battery cable to the charger before connecting the charger to electrical power.
  • Allow approximately 5–6 hours for a fully discharged battery.
  • The charger’s red LED indicates charging; green indicates a charged battery.
  • Disconnect electrical power first, then disconnect the battery from the charger.
  • Allow the battery to stand for at least 30 minutes before reinstalling it.
  • Recharge the battery within 24 hours after use.
  • Recharge it at least once every three months during storage.
  • Use only the charger and official battery specified for the Marlin.
  • Do not use, store or charge the battery above 104°F/40°C.

Seal and Nose-Cone Care

Before replacing the nose cone, ensure the nose-cone seal and sealing surfaces are clean, undamaged and properly lubricated with silicone grease. Close and lock the nose-cone latches completely.

Do not open the nose cone while the unit is in water. The battery housing interior must remain dry.

Cleaning After Use

  • Remove the battery immediately after use.
  • Do not store the battery inside the Marlin.
  • Rinse the seascooter in clean freshwater immediately after use.
  • Allow the unit to dry completely before storage.
  • Do not use detergents; use a damp cloth for cleaning.
  • Keep the battery compartment dry.
  • Store the unit vertically to help prevent deformation of the propeller nozzle.
  • For extended storage, open and remove the nose cone.
  • Keep the unit and battery away from direct sunlight and excessive heat.

Age, Supervision and Personal Safety

  • The Marlin is listed for ages 8 and older.
  • Adult supervision is required at all times.
  • The child must remain within their standing/swimming depth.
  • An approved PFD must be worn.
  • The Marlin is designed for one person.
  • It is not a life-saving device or buoyancy aid.
  • Tie back long hair or use a swimming cap.
  • Keep loose clothing, body parts and objects away from the propeller area.
  • Never attach the user, clothing or equipment to the seascooter.

Water and Operating Limits

  • Use in a pool or calm water close to shore.
  • Do not use in the open sea.
  • Do not exceed the 10-ft/3-m equipment depth rating.
  • Never release or leave the Marlin in the water.
  • Water type, currents, temperature and pressure affect buoyancy.
  • The unit has less buoyancy in freshwater, lakes and pools and may sink if released.
  • Do not use a damaged unit, charger or battery.

Air Travel with the Battery

The Marlin battery is rated at 12V and 4.5Ah:

Calculated battery energy: 12V × 4.5Ah = 54Wh

The FAA permits qualifying nonspillable wet batteries for portable electronic devices when they do not exceed 12V or 100Wh, are protected against damage and short circuit, and the battery and outer packaging are marked nonspillable. Spare batteries require strong packaging and quantity limits apply.

Do not describe the Marlin battery as airline approved. Confirm that the physical battery is marked nonspillable and obtain approval from the airline before traveling. Airline, TSA and international requirements may be more restrictive.

Is the Nautica Marlin Seascooter Right for Supervised Pool and Snorkeling Use?

The Nautica Marlin Seascooter is intended for families looking for a compact children’s underwater scooter with clear manufacturer age guidance. It is listed for ages 8 and older with adult supervision and can be used for pool play, swimming and snorkeling in a pool or calm water close to shore.

This single-speed kids’ pool seascooter reaches up to 1 mph/1.6 km/h and is depth-rated to 10 ft/3 m. The removable 12V 4.5Ah lead-acid battery delivers up to 60 minutes with normal intermittent use, while the manual lists up to 35 minutes when the trigger is held continuously. Charging a fully discharged battery takes approximately five to six hours.

Choose the Marlin when a longer normal-use runtime and replaceable battery are more important than minimum weight. The lighter Nautica Guppy may suit buyers who prefer a 3.5-lb lithium-ion model and require only 30 minutes of normal-use runtime. Neither model should be selected as a life-saving device, deep-diving scooter or open-sea DPV. Product age guidance, adult supervision, an approved PFD and the user remaining within their depth remain essential selection requirements.
