I stand to be corrected, but Ive traded boats every year for the past 10 years, and Ive always bought all the warranty available, so as to have it in place for the next owner, and it has never exceeded 5 years, total.This is Mercury warranty, from the factory. I think what you are getting is 3 years, plut two extended, in the optional purchase, for 5 total.Mike Whitten/Germantown, TN
