Re: Depth Finder
I just installed a Humminbird HDR650 on my runabout. I went with the external transom mount transducer, but they sell it both ways. I don't fret about drilling a couple of tiny screw holes on the boat as long as I use sealant. In any case, I got it shipped to the door for less than $85 so that ain't bad. Took about an hour and a half to install, but it was mainly due to me routing the cable through the factory wiring harness conduit. Has shallow/deep alarms and works up to something like 50mph. Three separate trim/bezel colors so you can try to closely match your existing gauges if you care.
