Hi there,

The transducer or the connection to it is suspect.

First, check the connections and the condition of the wiring.

Disconnect the transducer cable and securely reattach it again.

If it still has difficulty marking 25' then you will need to test the chartplotter with a different transducer, or replace your transducer.
