The case is all aluminum with included extra o rings for the water jacket. The bullet connectors fit like they should and this is serviceable. This is a 5mm shaft so an adapter was needed in my case but other than that cooling hoses were a direct fit along with mounting hole spacing lined up perfectly. ### ⭐⭐⭐⭐⭐ 8S Marine Motor *by on Reviewed in the United States 21 October 2024* This is a great motor. Ran test on 6S. Very quiet. Easy to install. Look to get in water next week. Great value. ### ⭐⭐⭐⭐⭐ This thing flys *by on Reviewed in the United States 17 August 2025* Super fast --- ## 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.jp/products/522239333-4092-brushless-rc-boat-motor-surpass-hobby-1250kv-brushless-motor](https://www.desertcart.jp/products/522239333-4092-brushless-rc-boat-motor-surpass-hobby-1250kv-brushless-motor) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-29*
