Depth & Temp

[Randy Dunster]

Recently purchased a 2012 Sea Ray 240 Sundeck ant the Smart Craft Gauge says Sys Fault OBD service soon. When cycling thru the different features Trim, RPM, Water PSI, Hours , Engine Temp they all work and report accurate readings. However Depth & Water Temp are not working. Prior owner had taken boat to a Sea Ray dealer and they ordered a new Through hull transducer for it. However it has now been on back order for well over a year. How can I confirm that the transducer is the problem? Are there any videos that show how to replace it and it’s wire harness once I can get the part? Any ideas in finding a replacement?

The SYS fault could be caused by the temper/depth issue... don't know for sure.

If not the transducer, it could be a bad connection at a plug. Trace the cable back looking for a connector. Both temperature and depth come from the same transducer. As far as replacement, from the picture it looks like you would remove the small triangle that is held in with the tie. Then the transducer would spin off.
