Leighbo - not sure if this is true because I haven't checked it out yet, but I have a 2004 750DC and started getting some cracking on my seats and went into the local Bass Pro Shops to talk to the Service guys about replacing them. They told me that if all it really was is cracking, that if I came in with the boat number, I could order the exact leather seat covers that matched the original seats and if I was able to get the seats off on my own, could take the covers to a furniture repair place and they could put the covers on for me and it would be much cheaper than having them do it as they would do the exact same thing but take a middleman fee. I plan on trying to get the seats off before I winterize and shrink wrap my boat. This definitely seems to be a far cheaper way to go than to replace them entirely, assuming that what they told me is correct.
