Replacing Worn Out Spark Plugs
Spark plugs that are worn out or damaged should be replaced immediately. Refer to your engine’s manual for the correct type of spark plug for a replacement.
Cooling System Care
The cooling system is crucial in maintaining the right operating temperature for your boat engine.
Understanding Your Boat’s Cooling System
Your boat’s cooling system circulates coolant around the engine, absorbing heat that the engine produces. It then dispels this heat into the water around the boat, keeping the engine cool.
Symptoms of a Failing Cooling System
Symptoms of a failing cooling system can include an overheating engine, coolant leaks, or temperature fluctuations. A proper diagnosis to these symptoms is crucial.
Routine Care and Maintenance for Cooling System
Regularly flushing the cooling system and replacing the coolant can prevent deposits and corrosion build-up. Always check for leaks and damages to hoses before setting sail.
