The Nautica Marine 500 Seascooter is a compact dual-thruster underwater scooter created for personal recreational swimming, snorkeling and scuba diving by qualified divers. Its three selectable speed settings provide controlled underwater propulsion up to 3.5 mph (5.6 km/h), while the product carries a maximum depth rating of 100 ft (30 m).

A replaceable 25.2V, 5Ah lithium-ion battery provides up to 45 minutes of operation under normal use or up to 35 minutes of continuous operation. Charging takes approximately three hours. The complete unit weighs 8.8 lb (4 kg) with the battery installed, making it substantially easier to carry than many larger lead-acid Marine Series models.

Dual triggers operate the thrusters, while the master switch, protective propeller grilles and battery-level indicator support controlled operation. An integrated camera mount allows a compatible sports camera to be attached, although the camera, housing, buckle and thumb screw are not included.

Choose the Marine 500 when you want a lightweight, three-speed recreational diving seascooter and are prepared to follow its age, diving-qualification, buoyancy, battery-care and operating requirements.

Dual-Thruster, Three-Speed Control

The Marine 500 uses dual thrusters and three selectable speed settings to provide controlled propulsion up to 3.5 mph. Both triggers start the thrusters; the manual explains how individual trigger inputs support speed changes and turning.

Replaceable Lithium-Ion Battery

Its removable 25.2V, 5Ah lithium-ion battery supports up to 45 minutes under normal use and approximately three-hour charging. The four-level LED indicator helps the user check remaining battery capacity before and during a session.

Lightweight Recreational-Dive Design

At 8.8 lb (4 kg) including the battery, the Marine 500 is compact enough for easier dock, boat and shoreline handling. Its 100 ft rating describes the unit’s operating limit—not a recommendation for an unqualified person to dive to that depth.

Integrated Camera Mount

An integrated camera mount supports compatible sports-camera setups for underwater recording. The camera, waterproof housing, buckle and thumb screw must be obtained separately and checked for compatibility before use.

Seawater-Oriented Buoyancy System

The manual states that the Marine 500 is designed for seawater. It has less buoyancy and may sink when released in freshwater, lakes or pools, so it must never be treated as a flotation or life-saving device.

Before First Use

  • Read the exact NAE23500 manual.
  • Fully charge the battery and inspect the unit, battery seals, terminals, locks and grilles.
  • Confirm the swimming area is free of boats, swimmers and other hazards.
  • Only operate the thrusters in water.

Charging and Battery Care

  • Remove the battery pod after each use.
  • Ensure the battery and terminals are dry before charging.
  • Use only the supplied charging unit.
  • Charging takes approximately three hours.
  • Do not charge overnight unattended.
  • Recharge after every use and at least once every six months during storage.

Freshwater and Saltwater Care

  • Rinse the unit and terminals with fresh water after use.
  • Dry the unit and battery before storage.
  • Do not use detergents.
  • Do not leave the seascooter in the water when it is not being used.

Seals and Buoyancy

  • Keep sealing surfaces free of sand and grit.
  • The unit is designed for seawater and may sink in freshwater, lakes or pools.
  • Never use it as a life-saving device or buoyancy aid.

Storage

  • Remove the battery from the unit.
  • Store the product and battery dry, cool and away from direct sunlight or flammable materials.

Age and Operating Limits

Is the Nautica Marine 500 Seascooter Right for Recreational Diving and Snorkeling?

The Nautica Marine 500 Seascooter is most suitable for an operator who wants more speed and a lighter lithium-powered design than the lead-acid models lower in the Marine Series. Its dual-thruster configuration, three speed settings and 3.5 mph maximum speed provide a meaningful step up for recreational snorkeling and qualified scuba use.

Its most important buying advantage is the balance between underwater performance and transport weight. At 8.8 lb including the battery, this Marine 500 underwater scooter is easier to carry than heavier lead-acid models. The tradeoff is runtime: the exact manual lists up to 45 minutes under normal use and up to 35 minutes when used continuously.

Buyers must also understand its buoyancy limitation. The unit is designed for seawater and may have insufficient buoyancy in pools, lakes and other freshwater. It must not be released, left floating unattended or used as a life-saving device.

Choose NAE23500 when three-speed control, dual thrusters, lithium power and lower land weight are the priorities. Select a different model if you need longer runtime, a product for an operator under 16 or equipment intended for commercial use.

Why Choose This Seascooter?

Why Choose the Nautica Marine 500 Seascooter?

The Marine 500 is designed for shoppers who want a lightweight, multi-speed underwater scooter for recreational snorkeling, swimming or qualified scuba diving.

  • Three-speed control: Select from three propulsion levels up to 3.5 mph.
  • Dual-thruster handling: Two thrusters and dual-trigger control support responsive underwater movement.
  • Lower carrying weight: The unit weighs 8.8 lb with its battery installed.
  • Replaceable lithium battery: The removable 25.2V/5Ah pack delivers up to 45 minutes under normal use.
  • Recreational-dive depth rating: The product is rated to 100 ft, provided it is used within the manual’s operating requirements.
  • Camera-ready design: An integrated mount supports compatible sports-camera equipment.

The Marine 500 is intended for operators 16 years and older. Scuba use is restricted by the manual to qualified divers, and the unit must never be used as a buoyancy aid. Choose the Marine 300 instead when longer claimed runtime is more important than lower carrying weight and slightly higher speed.
