16' SA450 Depth & Temp Not Working??

Hey folks, been a while since I've posted anything, but here is the problem. I took the boat out for the first time of the year a couple weeks ago and noticed that my Temp and depth readings are not working correctly. My water temp reading is -50°F and my depth gauge continuously reads 0.0ft.

I have about a 45 minute drive to the closest dealer, so I am trying to resolve the issue personally before i load her up. I did call the dealer who suggested that I turn the key to the ON position without starting and flip the battery switch off for 30 seconds. After repeating this several times with different time intervals, i haven't had any luck.

If anyone has a clue of how to correct this issue, I would be very appreciative. On a side note, everything else is working just as it should.

Guessing your through hull transducer has failed.

Easy swap, but not cheap

I am assuming from your response that the transducer covers both the temp and the depth?

I believe it’s an airmar DST800 triducer.

Is it typical for the speed to still work accurately with the other two functions not working correctly?

I appreciate the help Larry

Not sure, is your 2016 still under warranty?

It is, except I just went through their warranty page which has the below EXCLUSION in it. This to me makes me think it wouldn't be covered, but it never hurts to call the dealer.
