I'm looking for a complete power steering pump, reservoir, and pulley. I already have the merc bracket if someone knows the part number or vehicle make and year I can cross it over to napa and order one. Thanks Rob.

What year motor

I just put on a new power steering pump on my 1999 502 with serpentine belt set up. Went to Auto Zone with old pump and matched up with a chevy truck pump. Auto Zone part # 7087 matched right up. That is without the pulley. Used the pulley off the old pump. They even had a puller and pulled off the pulley for me. Only $58 and a life time warranty, can't beat that.

I think they are 91 502's.

The mercruiser numbers are Pump 16792A1 and the pulley is 73873A1. Hope this helps you

Thanks, for the numbers.
