Aqua Marina Motion Inflatable Sports Boat With T-18 Electric Motor

The Aqua Marina Motion Inflatable Fishing Boat with T-18 Electric Motor is a portable sports and leisure boat package for angling, camping trips and recreational use on suitable sheltered water. The 255 cm boat carries up to 185 kg and includes the 180W T-18 motor, oar set, foot pump and carry bag.

Manufactured from heavy-duty PVC, the Motion uses an inflatable I-beam floor, two main air chambers and one floor chamber. Oar holders, moulded oar locks, carrying handles and a perimeter safety grab line support practical use and transport. The boat can be propelled by the supplied oars or by the 12V T-18 electric motor.

What Is the Aqua Marina Motion Boat Used For?

The Aqua Marina Motion is designed for recreational boating where compact transport, manual rowing and low-power electric propulsion are required.

Suitable applications include:

• Recreational angling
• Calm lake use
• Sheltered river and canal use
• Camping and touring trips
• Leisure boating close to shore
• Accessing quiet fishing areas
• Family recreation within the stated passenger and load limits

Use the boat only in water conditions appropriate to its design, the experience of the operator and local navigation rules. It is not intended for rough water, strong currents, exposed offshore use or white-water conditions.

What Is Included?

• One Aqua Marina Motion BT-88821 inflatable boat
• One Aqua Marina T-18 electric trolling motor
• One oar set
• One foot pump
• One carry and storage bag
• Integral oar holders and moulded oar locks
• Factory-fitted side carrying handles
• Perimeter safety grab line

What Is Not Included?

• 12V battery
• Battery charger
• Battery box or retaining straps
• Additional electrical cable or connectors
• Personal flotation devices or buoyancy aids
• Anchor, mooring line or fenders
• Fishing rods, rod holders or tackle
• Dry bags and waterproof equipment cases
• Registration, licence or launch permits where required locally

How Many People Can the Motion Carry?

The stated passenger capacity is two adults or one adult and two children.

The total weight of passengers, clothing, battery, fishing equipment, food and all other items must remain within the 185 kg maximum payload.

Passenger count and payload are separate limits. The boat must not carry more people than stated even when their combined weight is below 185 kg.

How Is the Boat Constructed?

• Extra-heavy PVC hull material
• Two independent main air chambers
• One inflatable floor chamber
• I-beam floor construction
• Boston safety valves
• Perimeter safety grab line
• Side carrying handles
• Oar holders on both sides
• Moulded oar locks
• Compatible stern fittings for the supplied T-18 motor

The I-beam floor is designed to reduce movement through the inflatable floor and provide a more stable internal platform than a simple unsupported air chamber.

Can the Motion Be Used Without the Electric Motor?

Yes. The supplied oars allow the Motion to be used as a manually propelled inflatable boat.

Manual propulsion is useful when:

• Launching or approaching shore
• Manoeuvring in very shallow water
• Conserving battery capacity
• The motor cannot be used under local waterway rules
• Returning to shore if electrical propulsion becomes unavailable

The oars should remain onboard whenever the motor is being used.

How Does the T-18 Electric Motor Attach?

The T-18 is designed for compatible Aqua Marina boats, including the Motion. It uses the dedicated mounting arrangement at the stern rather than a conventional universal clamp-on outboard bracket.

• Confirm that the motor shaft is correctly positioned in the stern fittings.
• Secure all collars and mounting components.
• Check that the propeller has sufficient clearance.
• Confirm that the electrical cable cannot contact the propeller.
• Test forward and reverse operation before leaving the launch area.
• Disconnect the battery before adjusting the propeller or mounting assembly.

What Are the T-18 Motor Specifications?

• Supply voltage: 12V DC
• Maximum output: 180W
• Current draw: 14.7A
• Maximum thrust: 8 kg / 18 lb
• Motor weight: 2.35 kg / 5.18 lb
• Shaft length: 60 cm / 24 in
• Total length: 75 cm / 29.5 in
• Speed settings: One forward and one reverse
• Water-resistance rating: IPX4

IPX4 means the motor is protected against splashing water. It must not be treated as fully waterproof or deliberately submerged.

Is the Supplied Motor 500W?

No. The figures describe two different specifications:

• 500W: Maximum motor power permitted for the Motion boat
• 180W: Output of the supplied T-18 electric motor

Do not fit a motor exceeding the boat manufacturer's 500W maximum rating. Any alternative motor must also be physically compatible with the boat's mounting system and suitable for the intended waterway.

What Battery Does the T-18 Require?

The T-18 requires a suitable 12V battery, which is not included.

Select a battery and electrical installation capable of safely supplying the motor's published 14.7A current draw. Battery capacity in amp-hours affects operating time; a higher-capacity battery generally provides longer use but also adds more weight to the boat.

• Use a 12V battery only.
• Do not connect the motor to a 24V supply.
• Include battery weight within the 185 kg payload.
• Secure the battery so it cannot move or overturn.
• Protect terminals against accidental short circuits.
• Keep the battery and connections away from standing water.
• Use suitable electrical protection and connectors.
• Follow the battery and motor manufacturers' instructions.

Actual operating time depends on battery capacity, battery condition, passenger load, water conditions and the amount of time the motor is running.

How Should the Motion Be Inflated?

• Set the boat up on a clean, level surface away from sharp objects.
• Unroll the boat completely.
• Inspect the PVC, seams and valves before inflation.
• Inflate the chambers in the numbered sequence shown on the boat.
• Inflate the floor until it is firm but not excessively hard.
• Inflate the main chambers evenly.
• Close each valve securely.
• Recheck the boat after it has been moved into direct sunlight or warmer conditions.
• Release air if heat causes excessive internal pressure.

Use the supplied foot pump or another suitable low-pressure inflatable-boat pump. Do not use an unregulated air compressor.

Installation and Safety

• Read the complete Aqua Marina boat and T-18 motor instructions.
• Wear a correctly fitted personal flotation device or buoyancy aid.
• Confirm that the boat, valves and chambers are undamaged.
• Check that the oars and motor are secured.
• Check the weather, current and local navigation conditions.
• Keep within the passenger and 185 kg payload limits.
• Distribute passengers, battery and equipment evenly.
• Secure the battery and loose equipment.
• Keep the oars onboard as a secondary means of propulsion.
• Tell someone the intended route and expected return time.
• Keep children under direct adult supervision.
• Do not operate the boat while affected by alcohol or drugs.
• Observe local registration, speed and powered-craft rules.

Switch off and disconnect the motor from the battery before clearing the propeller, adjusting the motor assembly or working on electrical connections.

Care and Maintenance

• Disconnect and remove the battery after use.
• Rinse the boat and motor with fresh water after use in salt or dirty water.
• Remove weed, line and debris from the propeller.
• Inspect the PVC hull, seams and valves.
• Check the safety grab line and carrying handles.
• Inspect the oars, oar locks and holders.
• Allow the boat and accessories to dry completely.
• Remove dirt and sand before folding.
• Fold loosely to avoid repeatedly creasing the same area.
• Store the boat in its carry bag in a dry, ventilated location.
• Protect the PVC from prolonged heat, frost, fuel, solvents and direct sunlight.
• Store the motor and battery in accordance with their separate instructions.
