Along with the above question, I am planning on purchasing the Furuno paired thru-hull chirp side scan transducers P/N 455T-PR903 for my boat and due to the steep deadrise I need the high speed fairing blocks also. Do they come with them like the 22T-PR904 does (at the same price) or do I need to purchase separately? I just can't find any info on this as the high speed fairings aren't listed in any of the PR903 dealer descrptions. Thanks in advance for any assistance
