PCM 160°F Thermostat with 156-Hole Housing
Keep your PCM inboard engine running at its optimal operating temperature with this OEM-spec 160°F thermostat. Designed specifically for PCM marine engines, it regulates coolant flow to maintain consistent engine temperature — protecting against overheating and ensuring efficient combustion across a full range of operating conditions.
The 156-hole housing design promotes even coolant distribution through the thermostat, reducing hot spots and improving thermal stability. This is a direct-fit replacement for PCM engines that originally specified a 160°F thermostat with the 156-hole housing configuration.
Key Features
- Opening temperature: 160°F (71°C)
- 156-hole housing for even coolant distribution
- OEM-spec fit for compatible PCM inboard engines
- Regulates coolant flow to prevent overheating and cold running
- Direct replacement — no modification required
Best Use Case
This thermostat is the correct replacement for PCM inboard engines originally equipped with a 160°F / 156-hole thermostat. It is most commonly found in PCM-powered wakeboard boats, ski boats, and performance inboards. Always verify the OEM thermostat temperature rating and housing hole count against your engine’s service manual before ordering — installing the wrong temperature thermostat can affect engine performance and warranty coverage.
Parts Desk Insights
Thermostats are a routine maintenance item on inboard engines and are often replaced as part of a cooling system service alongside the impeller. If a customer is replacing the thermostat due to overheating, always ask whether they’ve also checked the raw water impeller — a failed impeller is the most common root cause of overheating on inboard engines. Cross-sell the PCM Marine Plumbing Elbow Fitting and PCM O-Ring Seal for customers doing a full cooling system service. The PCM Remote Coolant Recovery Tank Cap is also worth mentioning for customers servicing the closed cooling system. Confirm the engine model and year before ordering to ensure the 160°F / 156-hole spec is correct for their application.
