Clean your boat thoroughly 🧼🚤

Remove all fluids and batteries 🔋🧴

Remove all fluids from your boat, including engine oil, antifreeze, and any other liquids that may be in the boat’s systems. This is important to prevent any fluids from freezing and causing damage to the boat.

You’ll also want to remove the batteries from your boat and store them in a cool, dry place. Consider using a battery tender to keep your batteries charged during storage.

Protect your boat’s engine 🚤🔧

Winterizing your boat’s engine is essential to prevent any damage from the cold weather. This includes changing the engine oil and filter, adding antifreeze, and running the engine to circulate the antifreeze.

You’ll also want to flush out the engine with fresh water and grease all the fittings. Make sure to disconnect the fuel supply before running the engine dry.

Cover your boat ✨🛥️

Covering your boat is important to protect it from the elements. Consider using a fitted cover made from a durable material that can withstand harsh weather conditions. It’s also important to use tie-downs to ensure the cover stays in place.

For added protection, consider using shrink wrap to fully enclose your boat. This can help prevent any water or snow buildup.

If storing your boat outdoors, make sure it’s properly supported on its trailer and that the trailer is in good condition. Consider removing the tires and storing them indoors to prevent any damage.
