Wrong part by Eric - Bloomingdale, New YorkAugust 05, 2011
It was obvious when I was speaking to the person on the phone they had no idea what I was talking about. I even provided a part number and they still go it wrong. You need more than a person looking through a catalog of parts, you need educated people who know boats on the other end of the line.
