Marine Antifreeze

Marine Antifreeze: Protection in Freezing Temperatures

Winterizing your boat is performed before the winter months to protect your boat and boat engine from the low temperatures of winter that can cause damage. You basically drain out any water onboard and replace it with marine engine antifreeze. This prevents water from freezing and expanding, which can possibly damage your engine parts. Wholesale Marine carries boat antifreeze products from leading brands likeStarbrite.

While you might be tempted to use the automobile antifreeze you have on hand, it is not suitable for marine use. Boat antifreeze is non-toxic and specifically designed for use on your boat. Other antifreeze types contain harsh chemicals that are not approved for use on boats and can be damaging to the environment as well.

Marine antifreeze products are made with USP-grade ingredients, including propylene glycol. These additives not only prevent freezing but also help prevent rust and corrosion. Whereas auto antifreeze is made to be both a cooling agent and lowers the freezing point but can cause damage to marine engines.

Things To Consider When Winterizing Your Boat

Make sure, when selecting a boat antifreeze product, it offers the right temperature protection. Antifreeze is rated by the temperature at which the gas line will freeze, not the ambient temperature. The burst point of PVC pipes used in most drinking water systems is about -10°F (-23°C).

Starbrite Non-Toxic Antifreeze will provide burst protection and freeze protection within a range of +12°F to +16°F (-11°C to -9°C). When testing with a refractometer or hydrometer, freeze point readings on the PG scale will range from +12°F to +16°F.

A typical marine antifreeze rated for -50 F will only protect up to about -10 and freezing can start happening at around 15 F. Be on the safe side and select an antifreeze that is rated well above the coldest temperatures you are likely to experience.
