Replacement alternator for compatible pre-2003 PCM/Ford GT40 inboard charging systems.
Engine & part-number match

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.

Fitment & setup
Can I choose it by the boat year alone?
Compare the engine and existing alternator number, mount, belt and pulley arrangement, and wiring connections. The boat year alone does not confirm a match.
Which output rating and pulley do I need?
Send GT40 the current alternator label and pulley photos. Confirm the replacement output rating, supplied pulley and any retained parts before ordering.
