Hey guys I am new here and to the boating world. I just purchased a tracker with a 2006 merc. 25hp four stroke. I was wondering what oil is good for the crank case. Its a four stroke and I like amsoil or lucas for my powersports engines. is there any reason that I need to use mercury oil in the crank case or the lower end? Also does anyone know what oil filter will work on the motor other than the DEALER sold filters? thanks for help
