## Customer Reviews

### ⭐⭐⭐⭐⭐ Fits my Mako skiff 17
*by A***. on July 2, 2020*

Perfect fit for my Mako skiff 17/ colors and push key match original Mako/ Tracker original. Tracker switch is Taiwan made this replacement not sure but works perfect.Note: I was able to make a key copy at HD see key code on pictures BUT the HD key was a little thicker and would not fit on the switch chamber so I went to my local locksmith and he grind the HD key on the non flat side of the key and it work fine.

### ⭐⭐⭐⭐⭐ Works great
*by R***N on July 23, 2023*

Easy installation and fast shipping

### ⭐⭐⭐⭐ ALMOST and exact OEM
*by M***. on April 14, 2023*

Well built and fairly easy to splice the wiring together. A wiring schematic would be helpful, but if you color match you should be fine. I spliced into the OEM pigtail connector without a problem. I would recommend it.
