Review: Good for Tracker Pro 160 Bass Boat - Replaced an ignition switch on a Tracker Pro 160 boat. Worked perfectly. Not hard to install. Quality was good. I found it a bit hard to get housing tightened so that body did not spin, but got there.
Review: Perfect OEM replacement. - Purchased this for a 2005 Mercury Salt Water series 150hp and this replaced the OEM switch perfectly. Wires are all the same, dimensions are really close but the diameter of this switch is slightly larger. I had to modify my bracket a smidge to get it to fit but it was really easy to do and didn't take much effort. After installing, cranked right up and the automatic electric choke worked as well. And it was half the price of the actually mercury OEM part, so that was nice to save a few bucks, because as we all know, boats are just a hole in the water that you dump money into.

### ⭐⭐⭐⭐⭐ Good for Tracker Pro 160 Bass Boat

### ⭐⭐⭐⭐⭐ Perfect OEM replacement.

### ⭐⭐⭐⭐ Good replacement for Tracker Tx175
*by P***Y on May 25, 2023*

The ignition switch on my Basstracker TX-175 started acting strange and eventually got to where it was questionable if it would start the boat. Replaced it with this one and problem solved. Installation was pretty straight forward, wiring colors all matched the factory. For a good installation solder the wires and cover them with a good marine grade sealing connector. Installation took about an hour. Pulled the old ignition out of the boat by unplugging the connector. Soldered new switch to that connector and plugged it back in. Works great.
