Water temp stays at 32 deg.

[Launch SL]

Hi all 07 22ssv water temp on dash stays at 32 deg. Called Airmar the company that makes transducer they said to clear " marine growth from bottom of boat". Checked that no growth, tried to contact Medallion the company that makes gauges have had no luck, now turning to the experts at the Supra Board! Any suggestions?

Sorry - can't resist -- but it seems your gauge is "FROZEN"? -- bad, I know. Speed is working correctly, all other gauges?
