The Ultimate Mercury Marine Thermostat Upgrade for Your Outboard

We recently got our hands on the 892864T06 Thermostat Housing Assembly, and it’s truly a game-changer for Mercury Marine outboard owners. This replacement part is specifically designed for 65-150 HP outboards and perfectly substitutes OEM parts 8M0090819 and 892864A06, as well as Sierra 18-3633 and 18-3635.

What impressed us most was the precision engineering that ensures optimal temperature control for your engine. The housing is constructed with marine-grade materials that stand up to the harsh saltwater environment we often navigate. Installation was straightforward, with all mounting points aligning perfectly with our Mercury outboard.

For boaters experiencing overheating issues or simply performing preventative maintenance, we found this thermostat assembly to be an essential upgrade that delivers consistent performance. At this price point, it offers excellent value compared to dealership parts while maintaining the quality your engine deserves.
