I think i know my fuel issue but want some confirmation. I dealt with it last year in the hopes i could change my plugs and get peak performance again as usual, but alas at the plug change still could not make WOT RPM (4100 is best i could do) and still had some significant trans rattle indicative of a miss. Soooo, what is everyone's experience getting MerCruiser to fess up to the issue and at a minimum discount the replacement unit. I know of all the service bulletin and have heard stories of getting them to replace, but want see if anyone had some practical advice. I'm a realistic person and know we are talking about a 12 year old boat but it cant hurt to ask... Also what is everyone's source for injectors... part numbers?
