Hey Guy's I'm picking up a 2015 MPI 190 hp Viper MTX that is a dealer demo and will come with a years Yamaha factory warranty my question is how many of you opted for an extended service contract when purchasing your machines through a external party warranty company and have you found it necessary, have these thing's had big enough issues to warrant it. Three years extra for bumper to bumper coverage is being quoted to me for 2000.00 Canadian, what are some of your thought's and experiences on this as it will be my first Yammy and boosted four stroke?
