I was able to flip it over with the other hoses still connected, but be careful that your hoses aren't dry rotted as they could crack maybe if you do this. At first, I was expecting a thermostat to be sitting on the engine block, and I thought, dang, someone must have pulled it out already and running it wide open... well, I flipped the housing back and the thermostat was being held in it with the provided o-ring. I removed the o-ring, pulled out the old stat, ran a pick around the grooves a little, cleaned up the old gasket, put the new stat in, seated the new o-ring in the groove, put the new housing gasket on, and bolted back up.Now, my boat runs a perfect 160-170 when idled up. At idle, it runs around 190 and this is partly due to low idle not moving enough water through the engine and exhaust manifolds. I may also have some rust built up inside the cooling ports as well, and I may consider running a rust remover through it? Need to research first. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Fits great, great temperature regulation, wrong o-ring. *by T***E on Reviewed in the United States on October 5, 2021* The t-stat fits perfect. Housing was showing 157 deg f at Housing with temp laser, so great regulation. The o-ring is not the correct size as others have stated, I reused my original o-ring. The gasket was great fit. Overall I would buy it again. Maintained great temp both on the muffs and the lake. --- ## 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/102096095-thermostat-kit-with-gasket-for-omc-and-volvo-penta-4](https://www.desertcart.tn/products/102096095-thermostat-kit-with-gasket-for-omc-and-volvo-penta-4) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-20*
