Works great thus far. ### ⭐⭐⭐⭐ It works as expected. Great for the price. *by N***K on October 13, 2024* This replacement works like the original but I did find the Guage of wire was smaller. The battery voltage was 15 volts at full rpm, I may need to find a way to drop that. I never measured the voltage on the original, so it may have been the same. I don't think the battery charger worked when I bought the boat. ### ⭐⭐⭐⭐⭐ Perfect fit. *by R***N on July 15, 2023* Easy to install and fit perfectly. ## Frequently Bought Together - Sierra 18-5859 Marine Stator for Mercury/Mariner Outboard Motor - Oriental Power Replacement Mercury Power Pack Compatible with Mercury Outboard 4 Cylinder 40-125 HP Switch Box Power Pack 332-5772 A3- A7 332-5772A5,332-5772A7(J750) - Trigger For Mercury/Mariner Outboard 30HP-85HP 4-Cylinder 2-Stroke (1976-1997) 134-6452 96452A1 73372A1 73410A1 --- ## 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/15688380-sierra-18-5859-marine-stator-for-mercury-mariner-outboard-motor](https://www.desertcart.tn/products/15688380-sierra-18-5859-marine-stator-for-mercury-mariner-outboard-motor) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-26*
