xOverview

Materials, durability, and sealing
Constructed from high-quality stainless steel and copper for excellent heat conduction and strength. The mid-seal uses a thicker NBR compound, offering greater resistance to heat, oil, and corrosion, helping maintain a reliable seal over time.
Why this matters
The thermostat activates at approximately 143°F to help stabilize engine temperature and support consistent component performance. While outcomes depend on your setup, balancing temperature can contribute to steady operation and responsiveness across typical marine conditions.
- Replaces Mercury OEM numbers for a broad fit across V-6 carbureted and EFI variants.
- Thick, oil- and heat-resistant seal supports durable sealing in demanding environments.
Fitment and installation
- Two-piece design for straightforward installation and long service life.
- Compatible with Mercury Mariner V-6 carbureted and EFI engines, including XR-4, XR-6, Magnum II and Magnum III ranges; not intended for DFI Optmax.
Easy to handle and install with standard marine maintenance tools, this kit is built to align with fit, form, and function requirements and to support reliable operation under typical boating conditions.
