I have a 2003 Tracker V18 and on the console next to the ignition is a rocker switch that I
have no idea what it goes to. Can someone tell me what it is?

Highly unlikely that anyone can identify it . You are going to have to trace the wires , or turn it on and listen for something running . Might be lights , bilge pump or added for some accessory that the previous owner took out . It is a two or three way switch ?

Toggle next to ignition to me means choke or fuel enrichment activation. I have a push button adjacent to mine on a Crestliner that activates the enrichment valve for extra fuel during first starting procedures in particular.

Go to your device and check the wires color codes. One will go to ground or 12v and the other to your engine internal wiring harness where it connects to the boat's wiring harness and locate that wire. Once located, access the boat's wiring harness connecting pin and check the color code. Go to your dash toggle and see if that wire color code is attached. Problem solved.

Often boats have switches for optional items never installed. I wired my GPS and radio to the wiper switch, since I do not have wipers, nor a GPS/radio switch.

They are still in business so maybe a telephone call to Customer Service might get you the answer. Good luck!

one way switch factory installed. Bilge and light switch is on the right side of console along with livewell.

For my choke you push the key in. I will have to trace the wires. Thank you

I had that too with a Mercury Commander 2000 control box...the one that mounts ON the bulkhead. My Crestliner has the 3000 model which mounts IN the bulkhead and the ignition switch mounts on the dash board. That switch does not have the detent function for choking.

You're going to have to follow the wires. If nothing is hooked up, then you know it was an optional switch. If it has wires, tracing is the only option.
