I have a 1978 53 yacht fish with hold tank moniters that have given up. Any ideas on replacements. Last Resort

I have a Furuno FCV 582 color fishfinder on my 43 SX. It was on the boat when I bought it and appears to be an original install. I do not know what transducer I have. At cruising speed, the fishfinder looses the bottom. While this is not a huge deal because I have a backup fathometer, I am...
