I bought a new boat this past summer - Smokercraft Stealth 162 with a 50hp Merc. 4 stroke. I really like the boat and have no complaints with it overall. When I pulled out the battery for the winter I noticed that it does not have a label and the word "BLEM" is engraved on the top. The battery works well but should I demand a new battery? My only real concern is that if I have a problem with the battery it wouldn't be covered by a warrenty. Is it a common practice to put "BLEM" batteries in new boats?<br />RCS
