View product →Engine & part-number match
Marine alternator with listed comparison references 807652, 807652T, 3857813, 3860769, AC155616 and ARC60055. Match the installed alternator number, mounting foot, pulley and electrical leads. The LT1/LTR title and MerCruiser references need an exact part check before you order.
Before ordering
- Engine model and serial number; the boat year alone is insufficient.
- Complete number on the existing part and any replacement/supersession reference.
- Pulley, mount, regulator and electrical connections.
Exact replacement needs confirmation. Use the checks above so GT40 can confirm the correct part.
