The cost to store the boat over the winter is nothing compared to service and ownership. Don't worry about the warranty. The engines are bullet proof as long as you follow merc's maintence schedule. The words "save money" are not going to be used with this purchase. If you have to budget or worry about the cost, this boat should not be on you list. If I were you I would buy it now and run the piss out of it. Let the dice fly. That's the fun of it.
