Check with Merc, I would say yes but it might be a little more expensive..
Greg, would I buy the extended....yep, if I planned on owning the rig past the manufactures period. Never used to think that (as a matter of fact had never ever purchased an extended warranty on anything) way but my neighbor who is the manager of a Circut City and sold me a ton of electronics when we remodeled our house, convinced me to get one on a 57" widescreen HD TV. We went away for a week and when we got back found out that my wife turned the digital cable off (so the TV's screen was black) but did not turn the TV off. Burned out all of the "guns". Normally a $2,500 repair.....I was lucky. I would get one on the "heart" of your boat (IF you plan on keeping it OR if it is transferrable to a buyer).
