Sand or grit can be detrimental to the Yamaha Seascooter O-Ring. To remove sand or grit from the O-ring Seal, rinse the O-ring Seal in fresh water and apply fresh lubricant. If there is sand inside the Battery Housing, gently brush the sand from the unit, take care not to scratch the sealing surface.
If an O-ring Seal is damaged, replaced it with a new one and apply fresh lubricant before use. If you are unsure, please CONTACT US
