9. Replace the washer and nut and tighten with the socket wrench while holding the
Propeller; make sure it is securely fastened. (see Fig. 36)
10. Re-install the rear grille.
11. Install the Battery Pod and replace the Nose Cone when ready for use.
Sand or Grit on O-ring Seal
Ensure that sand/grit does not get on the seals as correct maintenance and care is essential.
To remove sand or grit from the O-ring Seal, rinse the O-ring Seals with fresh water and
apply fresh lubricant. If there is sand inside the Battery Housing, gently brush the sand from
the unit, taking care not to scratch the sealing surfaces.
If an O-ring Seal is damaged, replace it with a new one and apply fresh lubricant before use.

Flooding Events

Be sure to keep the O-ring Seal sand and grit free to ensure it keeps water out and to close the latches fully after accessing the battery chamber.
However, should the O-ring Seal not be clean or the latches not fully closed and water enters the battery chamber, your Seascooter will not be
damaged as it is designed for protection against accidental flooding.
Water Leakage Sensor (operates when propeller is turning)
Your Seascooter has a built-in water leakage sensor – when the unit experiences accidental
flooding, the motor will stop momentarily every 10 seconds. At the same moment, a buzzer
will beep every 10 seconds.
If water enters the battery chamber:
1. Remove the Seascooter from the water if safe to do so. Always observe safe diving
practices.
2. Remove outer and inner nose cone and tip out any excess water.
3. Remove battery pod.
4. If salt water has entered, rinse battery, battery pod and housing with fresh water.
5. Dry housing and battery pod thoroughly.
If the battery chamber is dry and the water leakage sensor continues to beep, there is a
leakage in the motor housing; contact customer service center/repair center for maintenance.
DO NOT OPERATE A UNIT WITH A SUSPECTED LEAK INTO THE MOTOR CHAMBER.
