I bought a used 24' boat 4 years ago and I had a Raytheon L365 Fishfinder
installed with a transom mounted transducer. That setup work very good. I
purchased a new 21' boat 3 years ago. I asked the dealer to install a the
same Raytheon fishfinder but they install a L265 with a in the hull
transducer. For the last 3 seasons I have had constant problem with false
readings on the L265. For example I could be in 80' of water but it would
indicate that I was in 3' and sound the shallow water alarm. I decided I do
not want to deal with that for another season. I believe the tranducer is
the problem. In an attempt to save money on buying and installing a new
fishfinder system, can I just switch to a transom mounted transducer
connected to my L265 Fishfinder? I would appreciate any other suggestions.

Thanks, Eddie

Yes, you can use a transom mounted transducer. I have a L265 and it came
with a transom mounted transducer.
I was getting a lot of the same kind of false readings and just accepted
them, thinking air bubbles were on the transducer, etc. My friend removed
the fish finder one day, thinking I didn't leave it in my bow rider while it
was parked in storage. (I do.) When I went to mount it the next day, one of
the 12 volt pins was bent. Trying to straighten it, I broke it. For $45,
Raytheon replaced the card the pins are soldered to and they also replaced
the touch pad. It works like new! So, it may be the 12 volt power
connection.

In your case I'd more likely say that the bent power pin was preventing the
rest of the pins from getting a good seal (no walrus jokes!).

Definately check you rconnection....maybe noise was getting in there
(shouldn't being a DC system though...hmm...)

Thanks for the replies. I'll check all of the connections first to see if
there are bent pins or something. If I don't see an obvious problem I'll
probably search for a new transducer. I want to do it while the boat is out
of the water. Once I put it in my slip it will be there until November.
