The ways to know if a boat thermostat is opening properly include checking the boat’s temperature gauge, looking for excessive smoke or steam from the engine, monitoring the coolant level (if any), and feeling the radiator hoses to determine their temperature.
Got water in your outboards engine oil? The cause could be a failed thermostat. Here's how to tell if an outboard thermostat has gone bad.
13 lip 2023 · In this comprehensive guide, we will explore various signs that indicate an open boat thermostat and provide practical solutions to address potential problems. By familiarizing yourself with these indicators, you can ensure the smooth operation of your boat’s engine and avoid costly repairs.
20 sty 2024 · When your boat’s engine is cold, the thermostat is closed, blocking the flow of coolant to the radiator. Once the engine warms up to a certain temperature, the thermostat opens up, allowing the coolant to flow from the engine to the radiator, where heat is dissipated.
When the thermostat is closed, it prevents the flow of cooling water passing through the outboard, thus increasing the motor’s operating temperature. As the temperature rises, the thermostat opens and allows coolant to flow through the outboard, thus decreasing its operating temperature.
Simply put, the engine thermostat is responsible for regulating the temperature of the engine. It helps to keep the engine from overheating by opening and closing the flow of coolant (a mixture of water and antifreeze) as needed. Let’s dive a little deeper into how a boat engine thermostat works.
In this classic DIY segment, Mike Gridley shows us how to change the thermostat in your boat, an often overlooked piece of boat maintenance, that should be done every two years. SUBSCRIBE to...
