Could I use the motor in combination with a third party battery?

– Technically the motor could be used with any battery as long as this can provide the necessary power. However, we are able to offer one of the lowest prices per Watt-hour available. – Lithium batteries offer more performance per unit of weight then lead-acid batteries. – In case you are not convinced by RDT batteries, we still advise to contact your dealer/service point to make sure the correct batteries are selected.

Could I use the Rim Drive in a salt water environment?

– All materials are carefully selected to maintain optimal performance and endurance. However, this requires the use of an anode to protect the motor. For additional instructions please see the manual of the motor.
