I ordered a Custom Built 572 for my boat and so far very satisfied with it. I initially had spoken to White Performance and Machine and experienced very poor customer service. When I found out that Skip White Performance was the company with items on eBay and gave them a call, I had a totally different experience. Skip White Performance was very easy to work with in deciding what I truly needed to order. From that point on, my communication with them up to my delivery was very positive. My received engine was just what I ordered and has performed as advertised. Thank You Skip White Performance for providing superior products and customer service.
