Is this a genuine original part?

This is a premium quality aftermarket replacement part from DB Electrical, manufactured to meet or exceed original equipment (OE) standards for marine performance.

How do I know if it is compatible?

We recommend checking your current part number against the OEM Cross Reference list. If your original unit is marked 89-96158 or 89-96158T, this is a guaranteed fit.

What does "Isolated Ground" mean for this part?

It means the solenoid's coil is not grounded through the metal mounting bracket. Instead, it uses a dedicated ground terminal (the 4th post), which is a common requirement for many Mercury Marine safety circuits.
