Questions & Answers

Is this a genuine original part?

This is a premium quality aftermarket replacement part, manufactured to meet or exceed original equipment (OE) standards for fitment and performance in marine environments.

How do I know if it is compatible?

We recommend checking the SKU/MPN and Cross Reference list provided above. If your original part matches any of these, it is a guaranteed fit.

What is a 1-wire alternator and can I use it on a 3-wire system?

A 1-wire alternator is self-exciting, meaning it only needs the main battery cable to charge. While it simplifies wiring, many of our units also support standard 3-wire plugs if your loom requires it. For 94A output, we recommend ensuring your main battery cable is at least 8 AWG or larger to handle the increased current.

Note: Please verify your original part number and mounting style against the references above before purchasing. Domain: 4drive.co.uk.
