Transducer

[Inthrustwetrust]

I was in the business for 1/2 my life. Airmar makes 75% of the transducers for all makes. Do yourself a favor and solder the wire connections using Epoxy Lined marine shrink tube over each splice after soldering , then cover the entire splice with said shrink tube. (you can stagger the splices to keep the overall diameter of the splice smaller)
You buy expensive Marine shrink tube at West Marine or you buy the same a lot cheaper at Harbor Freight.

I noticed the power and ground wires on the stock “Yamaha Airmar” transducer were very small, my wire strippers only go down to 22 gauge, and they were smaller that that, while the NMEA pig tail I made had 20 gauge, any thoughts on if the cheaper quality wire has anything to do with the failure?

The smaller wires are more flexible and less like to break from bending ,routing and fatique
