I have a K-type thermocouple for my two stroke already, can I buy just the gauge to read it? PN?

Asked by: Ryan1
Unfortunately we do not sell the gauge head by itself. All of our gauges come in a kit with the thermocouple and harness.

Does this gage have a high temp alarm set point and out that could drive an external alarm?

Asked by: 2002 7.3
This does not have a high temp alarm set. You would need to look at one of our pro control gauges.
