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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/140261082-boat-engine-87-17009a2-starter-ignition-switch-for-mercury-marine](https://www.desertcart.tn/products/140261082-boat-engine-87-17009a2-starter-ignition-switch-for-mercury-marine) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-07*
