Hi all,
I'm trying to sort out why my brand new garmin 547 xs reads my brand new tohatsu engine temperature 50 degrees F hotter than it actually is (according to my infra-red heat gun).
Specifically the garmin says my cooling water temperature is 175 degrees F when my heat gun says it is 125 to 128 degrees F.
I have the honda/tohatsu factory service manual but it does not give any real detail on sensor parameters and this is a new motor so I should not be taking it apart to trouble shoot it.
I'm new to nmea2000 networks so I'm trying to figure out if this is a sensor issue, a network issue, or a garmin issue.
Does anybody have direct experience in this sort of stuff?
I want to know what is happening so I don't get stuck in the loop where tohatsu says it is a garmin problem and garmin says it is a tohatsu problem
