Re: Preference... OMC or Mercruiser??
Most will tell you to go Merc or Volvo, since OMC is out of business, parts for Cobras are available. You have to find a dealer who sold Johnson/Evinrude, they can ususally order just about everything you need. I have had no problems getting parts for my 1988. Also a lot of parts are available in the aftermarket or on various websites. As far as the Cobra SX, that is the joint venture one made with Volvo, from looking at many parts diagrams, it looks to me to be the same as the Volvo SX (same parts diagrams, I mean exactly) so Volvo parts will most likely fit. First you should find out if you can find someone who will work on the Cobra, because many will not, esp the older dog clutch ones (86-93. If you find a newer one with the Volvo style cone clutch (94 and up) see if a Volvo shop will work on it.I for one would not be afraid of getting a 94 and up model since it was much improved at that point. Too bad they didn't get these right the first time, when they are set up right they really do shift well, even better than some Mercs.
