GT40 alternator upgrade-kit listing. Match the current alternator label, engine, mounting arrangement, pulley and electrical connections. Confirm the supplied kit components before ordering.
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.
