06 SAN gauges issue

[ditchdoc7]

Looking for Help/suggestions

2006 SAN TE with 330hp

Issue: All of the dash gauges work intermittently. when boat is powered up and started, the gauges (digital and analog) will not respond. But when the boat is put into gear and given about half throttle, the gauges will work for a few seconds and then stop. (this is all the gauges oil,temp,tach,speed etc). Perfect Pass works fine.

History: this problem is new onset after a recent new flooding mishap over the weekend. the boat was in a covered boat slip when a pop-up storm rolled in and the automatic bulge switch wasn't on (yea, stupid oversight) Water filled the inter bottom via run off from covered dock. water was pumped out and boat checked out good. No Running issues other than the gauges.

Suspect: I suspect that there may be moisture in the dash breaker box causing the issue.

Looking for opinions/insight.

Thanks

To try to help the next person...... The problem was found in the Faria Gateway box. the rubber seal failed and caused moisture to enter the circuit board. this wiped out all the telemetry to the dash. Had to replace the box. all is good now.
