the starter on my boat has a sticker attached that states that the starter meets marine standards and it is the original starter so i know it is ok. the sticker is coming off which got me to thinking about how to visually tell if the starter on a boat is marine rated or not. if someone was looking to buy a used boat, how could they tell? by design? special markings on the housing? and what about the alternator? any special design features here too?
