Good To Know

Q: Will this sensor plug into the factory harness? A: Yes, it is made to connect to the original wiring plug and sensor port on 1993 to 1996 SPI 580 models. Confirm your serial number and existing connector shape before ordering.

Q: Do I need any extra parts to install it? A: No special tools are required, though a thread sealant rated for marine coolant use is a good idea. Always let the engine cool fully before removing the old sensor.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
