Abstract: The Outboard motor quick connect system allows the user to easily flush an outboard boat motor by combining a permanently-affixed quick-connect fitting with a locking and sealing cap. The combination allows the quick-connect fitting to remain affixed to the motor, but without creating a risk of leaking during operation. The prevention of leaks is important because the flushing connection is part of the boat cooling system. When the boat motor is in operation, an internal pump draws surrounding water up into the motor. If the flushing connection is left open, or leaks, the water drawn in by the pump will be lost, exiting through the flush connection. Thus, while having an easy to access flush connection is important to encourage the user to flush the engine, it is critical that the connection is watertight.
