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.
The manufacturer’s package list includes:
A camera, camera mount, spare battery, carry bag and separate replacement charger are not listed as additional included items.
Battery charging and safety must be handled by an adult.
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.
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.
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.

The Nautica Marlin Seascooter (NAE23003) has been fantastic for family water fun. Cruising at speeds up to 1.0 mph is safe and manageable for kids, and the lightweight frame makes it easy to carry down to the beach.
Pulls smoothly in calm water and pool settings down to 10 feet. Rated 4.5 stars because you need to be very meticulous about cleaning sand off the rubber O-ring seal before closing the battery chamber to ensure a watertight seal.
The built-in GoPro camera mount holds securely for steady underwater video. Positive buoyancy ensures the Marlin scooter floats right back to the surface when released. Fast packaging and shipping from Mariners Warehouse.
We get roughly 50 to 60 minutes of total run time per charge out of the Marlin NAE23003. Dual-trigger safety mechanism works great to prevent accidental starts. Just remember to apply silicone grease to the seals regularly.
Arrived well-packaged with charger and seal lubricant included. Intuitive operation makes it effortless for beginners to explore shallow water without getting tired.
