I haven't posted much since I bought my first Allison and joined the board last year, but this one got my attention. I just completed the hydraulic steering conversion in my XB2003. I work part time for a local dealer and priced out the SeaStar helm, cylinder and hose kit at "wholesale" prices, and talked to Bill at Allison about ordereing everything else (steering wheel, trim switch, etc.). I thought I would save $ by ordering the major cost items locally where I can get dealer pricing, but found that ordering the whole package directly from Allison was no more, and if anything, a little less. The conclusion I came to is that Allison can't be marking up the SeaStar components much, if at all. My experience is that you won't do any better than ordering from Allison.
