When your motor is in use, remove your connector caps to prevent them from coming loose and getting lost. The Bixpy Connector Caps are held to the connector body with a small tether, that will not withstand the force of water while the Bixpy J-2 Motor is in use. So it is best to remove them while motoring.
Never ever cap a wet connector – let the connector dry before placing the cap and storing. It is important that the connector caps are installed firmly when your connectors have a chance of being exposed to water.
