Thermostat 895338 / 18-3556 For Force & Mercury Outboard Motors 25-55 HP | Replaces F97068

About This Product

This is a replacement thermostat for a range of older Force and Mercury outboard motors, typically from the 70s to 90s, in the 25 to 55 horsepower range. If your engine is overheating or taking forever to warm up, a stuck thermostat could be the culprit. This part matches several OEM numbers: 895338, 18-3556, F97068, and others (check the list to confirm it fits your specific model and year). It's a simple, pre-calibrated component that regulates coolant flow to keep your engine at the right temperature. Installation is a direct bolt-on replacement – usually located under the thermostat housing on the engine block. A vital, inexpensive part to keep your old outboard running smoothly and prevent serious overheating damage. Always double-check your engine's HP and year before buying.
