997 losing bottom
Posted: Wed Mar 09, 2016 8:15 am
I have an original 997 C unit, with a transom mounted transducer.
I've always been able to read depth even when on plane at 42mph.
I just started losing bottom when I get past 25mph.
It will read fine when I first get on plane, but then, once I get past 25, it will read fine for a few seconds, and then it drops to reading 3.9 feet until I come off plane again.
What caused the change?
