How To Winterize Your Boat Step-by-Step
Winterizing your boat is an important task that should not be ignored. It will save you time and money in the long run.
Follow these steps to winterize your boat and protect against damage.
Step 1: Clean and Dry the Boat
Before winterizing your boat, it's important to thoroughly clean it. This includes washing the deck, seats, and other areas of the boat. Remove any covers, such as canvas, and make sure the boat is completely dry. This will help prevent mold and mildew growth during the winter months.
Step 2: Maintenance Check
Inspecting the boat and performing any necessary maintenance before winterizing is also important. This includes:
- Changing the oil and oil filter before winterizing the engine to protect against rust and corrosion.
- Checking the belts and hoses and replacing any that show signs of wear or damage.
- Inspecting the impeller and replacing it if necessary. (Note: the impeller helps to pump water through the engine's cooling system.)
Step 3: Remove and Store Batteries
Take the batteries out of the boat and store them in a warm, dry place. Batteries can freeze in cold weather, causing damage to both the battery itself and the boat's electrical system. Make sure to store the batteries in a place where they won't be exposed to extreme temperatures.
Step 4: Drain the Fuel System and Add Stabilizer
Empty the fuel tank completely. Any leftover fuel can cause damage to the system. Then, add a fuel stabilizer to the tank and run the engine for a few minutes to ensure it is distributed throughout the fuel system.
Step 5: Winterize the Engine
Winterizing the engine is one of the most important steps in preparing your boat for the winter months. To winterize the engine, you will need to:
- Drain the engine block: To do this, locate the drain plug and remove it. This will allow any water in the engine block to drain out.
- Flush the cooling system: You can flush the cooling system by running water through it. This will help to remove any debris and contaminants that may have accumulated over time.
- Add antifreeze: Antifreeze helps to prevent engine freeze damage, as well as rust and corrosion.
Step 6: Check Belts and Hoses
On most boats, belts and hoses can be found running between the engine and other components, such as the alternator, water pump, and raw water pump. Inspect the belts for any cracks, fraying, or other signs of wear. Belts should be tight and should not show signs of slipping. If you find a damaged belt, replace it immediately.
Next, inspect the hoses for any cracks, leaks, or signs of swelling. Hoses should be free of kinks and other obstructions that could restrict flow. If you find a damaged hose, it should also be replaced immediately.
Step 7: Inspect the Impeller
The impeller helps pump water through the engine's cooling system. It is typically located in the raw water pump. Remove the pump cover and inspect the impeller blades for any cracks, chips, or signs of wear. The blades should be flexible and free of any damage. If you find damaged blades, replace the impeller.
Step 8: Grease Moving Parts
Grease the steering and throttle cable and any other moving parts to protect them from rust and corrosion. Make sure to use marine-grade grease specifically designed for boats.
Step 9: Store the Boat Properly
Storing the boat properly is essential for protecting it from harsh weather conditions and preventing damage to its exterior. Cover the boat with a high-quality cover and keep it in a dry place, preferably indoors.

Engine Maintenance Tips
By performing regular maintenance, you can help ensure the longevity and performance of your boat's engine. If you are unsure about how to perform any of these tasks, it is recommended that you consult a marine mechanic for assistance.
Tip 1: Regularly Check the Oil and Oil Filter
Check the oil level on a regular basis and change the oil and oil filter around every 100 hours of operation or once a year (whichever comes first). Fresh oil ensures proper lubrication and helps to remove any contaminants from the engine.
Tip 2: Check the Coolant Levels
Check your engine's coolant levels and ensure they are filled to the appropriate level. Coolant regulates the temperature of your engine and prevents overheating.
Tip 3: Inspect the Belts and Hoses
Regularly inspect the belts and hoses for cracks, leaks, and signs of wear. Belts should be tight, and hoses should be free of obstructions that could restrict fluid flow.
Tip 4: Clean or Replace the Air Filter
The air filter removes contaminants from the air that enter the engine. Again, clean or replace about every 100 hours of operation or once a year (whichever comes first).
Tip 5: Check Spark Plugs
Spark plugs are crucial in starting the engine and ensuring proper combustion. Replace them if they are worn or damaged.
Tip 6: Inspect the Fuel System
Check the fuel system for any leaks or signs of corrosion. Clean the fuel tank and fuel lines regularly to remove any contaminants that could clog or cause damage to the engine.
Tip 7: Maintain the Boat's Propeller
Check the propeller for any nicks, dents, or signs of wear. A damaged propeller can put stress on the engine and cause the boat to vibrate. If the propeller is damaged, it should be repaired or replaced ASAP.
Tip 8: Perform Regular Tune-Ups
Have a marine mechanic perform a regular engine tune-up to ensure that all parts are functioning properly. This may include checking compression and fuel delivery, among other things.
