Keeping a close eye on engine temperature is second nature for anyone who spends serious time on the water — and that’s where the Mercury Marine Sensor Dual Port Temperature - 8M0122888 steps in. This sensor doesn’t just give you a single snapshot; it tracks temperature readings from two ports at once, giving you a much clearer picture of how your engine’s running under load. Whether you’re cruising at speed or idling near the dock, knowing both sides of the story can make all the difference.

Built to work seamlessly with Mercury’s SmartCraft system, it feeds data straight to your helm, so there’s no guesswork. It’s designed to handle the actual conditions boats face — salt spray, vibration, and the constant pounding that comes with open water. And because it’s an OEM Mercury part, you know it’s built to the same standards as the rest of your engine — no compatibility headaches, no unreliable readings.

What makes it worth installing:

• Monitors temperatures from two ports at once, giving a fuller diagnostic view
• Designed for plug-and-play compatibility with SmartCraft displays
• Built tough with corrosion-resistant materials to handle saltwater environments
• Delivers reliable, real-time data so minor issues don’t turn into big problems

Whether you’re dialing in performance or just keeping tabs on engine health during long runs, this dual-port sensor provides information that helps protect your investment.
