Details:
We were fighting an idling problem on a 1075 that wound up being the taps sensor, not iac motors, so I took them off after only about 1 hour of run time. Mercury Racing iac for 850SCI, 1075SCI or 1200SCI applications: this is 2ea of the designed specifically engines. I bought these from performance boat and installed them for about an hour. There are 2 of these required for each engine.
I have them listed for a good discount on here. Made in the USA.
