Product Details

The OMC 0765559 Thermostat Assembly is a genuine OEM cooling system component designed for Johnson and Evinrude outboard motors. This thermostat assembly regulates engine operating temperature, ensuring optimal performance and preventing overheating or running too cold — both of which can cause long-term engine damage.

Rated at 140°F (60°C), this thermostat opens at the correct operating temperature to allow coolant flow through the engine's raw water cooling circuit. It is a direct OEM replacement, ensuring a precise factory fit with no modifications required.

Key Features:

  • OEM thermostat assembly rated at 140°F operating temperature
  • Designed for Johnson/Evinrude/OMC outboard engines ranging from 75–175 HP
  • Compatible with V-4 and V-6 two-cycle outboard configurations
  • Superseded by OMC part number 0435491 (also cross-references as 0437090)
  • Aftermarket equivalents include Sierra Marine 18-3544, Mallory Marine 9-43032, and GLM Marine 13130
  • Direct OEM-specification fit — no trimming or adaptation required

Replacing a worn or stuck thermostat is a critical part of outboard engine maintenance. A failed thermostat can cause your engine to run hot or cold, reducing efficiency and potentially leading to costly repairs. The OMC 0765559 restores proper thermal regulation to keep your outboard running at peak condition.
