Fish / Depth Finder Connections?

[coolguy982]

My '88 Thundercraft came prewired for a fish or depth finder. There is a Humminbird transducer installed and wiring going to the dash. I'd like to add a depth finder to the boat and have been looking at some Humminbird models, but the connections on the finders don't seem to be the same as the pre-wired connections in the boat. I'm assuming the boat connections are older/outdated connections since the boat is an '88 model. I've attached a photo below of the power and signal connectors. Can anyone tell me whether the the connection types are current or outdated? And if they are outdated, can I find some sort of converter to a newer connection type or should I just cut off the connectors and rewire new connectors?

Thanks for advance for any help!

If it is HB, probably an old LCR. HB has not been using round connectors like that for a number of years.
