Troubleshooting & FAQ
How do I know if this alternator fits my engine?
The best way to ensure compatibility is to match your original part number to one listed in our Part Number Matrix. You should also check our Engine & Model Compatibility tables for your specific engine model and production year. Pay close attention to mounting points and electrical connections.
Does this alternator come with a pulley?
No, this alternator is sold without a pulley. You will need to reuse your existing pulley or purchase a compatible one separately (such as Volvo Penta part 841812 or 841813).
What are the signs of a failing alternator?
Common signs include dimming dashboard lights, a battery warning light on your console, a weak or dead battery that won't hold a charge, or a grinding/whining noise coming from the engine bay.
Some parts are listed as 61A, but this is 60A. Will it work?
Yes. This 60A alternator is a direct replacement for parts listed as 60A or 61A. The minor difference in amperage does not affect performance or compatibility for the listed engine applications.
What is the "W" or tachometer terminal for?
The tachometer terminal is a connection point used to send a signal to your boat's tachometer (RPM gauge). This alternator includes one for vehicles that require this type of connection.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
