This is the Sierra 18-6849 alternator. The maker's part number is 18-6849 and its barcode is 808282310677. Beyond the name and those two numbers, nothing here describes the alternator: no output rating, voltage, engine fitment or ignition protection is stated. Match the part number to the unit you are replacing before relying on it.
Our take
The Sierra 18-6849 is defined by its part number and UPC 808282310677, with no output rating given. On a boat that means checking 18-6849 against the alternator you are replacing, since amperage is not stated.
