I have a 15 hp Mariner that will be stored outside (covered) thru a Michigan winter. <br />A boat shop offered to winterize it for $45. <br />Is this necessary? What happens if I don't winterize it?
I have a Mariner 15m. I need to know what year it is.<br />There are 3 sets of numbers listed on it.<br /><br />Code 684C S<br />Seriel # 054118<br />and some other # 6840 8 054118.<br /><br />I want to buy a service manual but I don't know the year.
