This Sierra alternator, part number 18-5965, is a 65 amp unit for MerCruiser engines. It has a V-belt pulley, so it belongs on belt drives that use that pulley type. It is listed as interchangeable with Mallory 9-19103, MES 3159M and Arco 60065, along with a run of MerCruiser numbers. Check the pulley against your existing alternator before swapping.
Our take
The V-belt pulley is the first thing to check on this 65 amp alternator, because it only makes sense where the drive uses a V-belt. The advice given is to verify the pulley against your existing unit before swapping.
