2017 Craz water temp reading

[clark]

Had my boat in the water then had a voltage issue and had to take it to the dealership for service. Got it back and now the water temp shows -99. Wondering if there is a breaker that controls it. Anyone know for sure?

No. My error was low voltage. It was a bad alternator

I just had the exact same problem on my 2018. How did you fix your water temp?

Anyone figure this one out? My 18 Mojo water temp is stuck on 136°

I’m also looking for this answer, for a 2017 Craz.

My helix had a water temp stuck at 136. Took it to the dealership and they said it was a faulty sending unit.

Seems like a simple warranty fix

Mine read -50 on my Supra SR. Had to put a sending unit in it. I just had the dealer send me a new one under warranty, it was simple to install. It fixed the problem but a month later my whole dash went out and was also replaced under warranty.
