I have a used but supposedly rebuilt Jabsco DJ09201 seawater pump. I turned it and it turns in the counter-clockwise direction when looking at it from the front of the engine but doesn't seem to turn in the clockwise direction. Unless I am having brain fade, it should turn in the clockwise direction on a 5.7L gm engine when viewed from the front. I understand about putting the impellor in with a twist for correct rotation. Do these pumps work either way just by rotating the impellor in one way or the other? I will be taking it apart to confirm the recent rebuild but wanted to make sure that the pump is universal in that it can run either direction with a properly set impellor. Maybe it was built incorrectly. Thanks...
