I purchased a used 1985 25.5 several years ago.  The "SR" depth finder worked well until about 4 years ago.  I shipped it back the the manufaturer in New York I believe and it was "rebuilt" and worked great for to last few years.  Now it's down again.  Was this factory equipment?  Is there a replacement that fits in the original hole and works without replacement of the transducer?  (I thinks it's still good)  Or what would be your recommendation?  Thanks for your help.
