The fix just came out a couple of weeks ago, so it should apply to all the new stuff that's out there. I would assume anything Mfg. from now on will contain the new program. I don't know about older engines that may be out of warranty now. You'd have to contact their customer service and see if they would work with you(or have your dealer contact them). The one's I've done are on 2003 model boats. Older ones don't seem to be having as much of a problem.

Thanks Bob for the reply/info.
