We have a boat w triple 08 300 Suzukis, 400 hrs. We purchased the motors new and they were sold to us under the pretenses of a total of 6 year warranty, 3 and an extra 3 by Suzuki. Never any mention of Cornerstone, a 3rd party warranty company and any additional registration. These motors have had 2 major warranty repairs and each time, they have been re registered in the owners name, as they initially show up as not reggistered. They have been repaired under warranty after correcting the registration. We now have a blown gearcase, factory warrant expired 2 days before the case blew and now we are being denied our extended warranty and again being ttold that we never registered the motors properly. I have all of our previous warranty and non warranty repair reciepts in the proper registraion name and my boss has told me to turn it over to his in house legal department. Has anybody else had this problem?
