I recently installed a bow-mounted fishfinder and am looking for some kind of quick-connect/disconnect fitting for the power cord. I'm using a pair of plastic covered terminals now but would like something more pro looking.  Something along the lines of a trolling motor plug but much smaller for low amperage. Any suggestions?

Didn't the fishfinder come with a quick disconnect plug?

Just the 7-pin plug if that's what you mean.  The transducer is mounted on my trolling motor and when I remove the trolling motor I need to disconnect the line from the power source.  The power is coming from the fuse block under the dash, that's the line I need to disconnect at the bow.  Hope I'm explaining this correctly.
