The boats a year old and I got the thing in the mail to extend the warranty from Mercruiser. Got a 496 Mag. I take care of all required Maintenance and while I may take it full throttle every on occasion I am not one to constantly run the engine very hard. Considering the cost of these freakin warranties what is everyone's take on paying thousands of dollars to extend????? What could like break and what would it cost if I didn't have the warranty????
