What is the general consensus on extended warranties for Mercury 4 stroke motors? I have both a 115 Pro XS CT and a 60 CT. Both motors currently have 3 years of platinum + 2 years of gold for a total of 5 years. I can extend that another 3 years, but have several options on types of warranty. The big difference between gold and platinum are electrical components from what I can see. I am leaning towards extending the warranty on the 115, but was hoping to get some alternate opinions. Thanks everyone.
