Got a couple questions...I just bought a Lowrance GPS/fish finder and will be mounting transducer today...<br /><br />Any opinions on whether I should run the cable into a drilled hole above the water line or just run the cable up and over the back of the boat. I have 18' Sea Pro with outboard.<br /><br />Also, I want to run power to accessory switch in center console, but need more wire. What wire should I get for saltwater use? Any other hardware needed to wire to switch?<br /><br />Thanks.
