Outdoor condensor unit motor tailcone

It looks like stabbing this onto a 3 5/8" bolt circle central air conditioner condensor fan motor will increase airflow. i've not tested this yet.

measured an average increase of 2% airflow with fan motor tail cone. used in conjunction with a Mars 10874 high efficiency ECM, soft start, fan motor will have good savings and prevent water from dripping on the new motor.
