What Kind Of Antifreeze Do People Use To Winterize A Boat Motor?

When winterizing a boat motor, it is important to use the right kind of antifreeze. The type of antifreeze used depends on the type of engine and the climate in which it will be used.

For most boat motors, a propylene glycol-based antifreeze is recommended. This type of antifreeze is non-toxic and biodegradable, making it safe for use in freshwater and saltwater environments. It also has a low freezing point, which helps protect against freezing temperatures. Propylene glycol-based antifreezes are available in both concentrated and pre-mixed forms.

In colder climates, an ethylene glycol-based antifreeze may be necessary to protect against extreme cold temperatures. Ethylene glycol-based antifreezes are more toxic than propylene glycol-based ones, so they should only be used when absolutely necessary. They are also more expensive than propylene glycol-based antifreezes.

It is important to check with your boat manufacturer or engine manual to determine the best type of antifreeze for your particular engine and climate conditions. In addition, you should always follow the manufacturer’s instructions for winterizing your boat motor to ensure that it is properly protected from freezing temperatures and other damage caused by cold weather.

By using the right kind of antifreeze when winterizing your boat motor, you can help ensure that it will remain in good condition throughout the winter months and be ready for use when spring arrives.
