On the rear right bank, down by the starter on the block is aSerial Number, M324683. This is a 4.3 vortec, 2bl carb in a 2002 Smoker Craft boat. I'm trying to find a starter and alternator but any site I'm on doesn't have the this serial number. The starter looks like any other starter from a gm product but I'm wanting to make sure I get the correct one. The breather is was replaced before I bought the boat and no numbers was transfered over. Any help is appreciated.
