When to de winterize boat?

There is no hard and fast date for winterizing your boat, it will largely depend on when the end of the boating season is in your area, You should also wait until you’re certain you’ve finished using your boat.

As a general rule, you should look to winterize your boat before the temperatures drop below 25 degrees Fahrenheit, approximately -3 degrees Celsius. To be safe, it is best to start winterizing before temperatures drop below freezing point, 35 degrees Fahrenheit or 0 degrees Celsius and ideally, before they get below 40 degrees Fahrenheit or 4 degrees Celsius.

While one night below freezing will not do your boat too much damage, if you have several cold nights in a row and the temperature does not get above freezing during the day, your boat is much more susceptible to freeze damage. This means it is best to exercise caution and winterize before it reaches this point.

Of course, every region is different and knowing when to winterize your boat will depend on location-specific information. Let’s take a look at some approximate timings for different regions around the world.

In the US, the best time to winterize varies dramatically depending on which coast you’re on and how far north or south you are. The northeastern coast will generally get colder a lot faster than warmer areas, so you need to factor that into your winterizing plans. By December you can expect to find temperatures low enough that winterizing is necessary on the East coast. That being said, it is not uncommon for temperatures to drop below freezing in October and November too so you should look to start winterizing in the Autumn. You may find yourself starting before Thanksgiving and on some years, even as early as September.

If you’re based on the West coast, you will have a lot more time to spare and can stretch out the season for long. Many boaters in California don’t bother winterizing at all. Despite this, it’s worth remembering that temperatures can still get below freezing in California and freeze-related boat damage can be rife come the spring. The same goes for Florida boat owners. Just because you live in a warmer climate, it doesn’t mean you’re immune to freeze damage!

Further north on the West Coast, you will probably want to have your boat winterized by December, in preparation for the colder weather to come, especially in January. Ultimately, you’ll need to keep an eye on the temperatures through the winter but expect to get started around the end of the year.

Winterizing in the UK is also location specific. As the UK benefits from varying climate regions, when you need to winterize your boat will depend heavily on where it is being stored. Some boat owners start preparing for winter as early as September to avoid any negative effects from a rapid temperature drop that could hit at any time.

On the other hand, many boat owners on the West coast of England, for instance, sail all year round, not bothering to winterize at all. Most years, temperatures rarely drop lower than -5 degrees Celsius (23 degrees Fahrenheit) so people tend to take the risk. This comes down to your personal choice. However, the further north you go, the more at risk you are from freeze-damage. In Scotland, winterizing tends to happen around October or November.

Generally, winterizing is not such a pressing matter if your boat is in the Med. Temperatures rarely dip below freezing in popular winter storage spots like Greece, Turkey and Spain. One of the exceptions is northern Italy where temperatures can drop below freezing in the winter months. In these instances, it’s a good idea to winterize your boat in November or December and wait until spring when you’re out of the danger zone. Alternatively, you could sail down the coast and spend the winter in Sicily where there’s no need to winterize!

The conditions to look out for when deciding when to winterize your boat is evidence that the temperatures are getting lower. In temperate climates, you can tell that winter is approaching as the leaves change color and the nights get longer and colder and you should feel a chill in the air. Generally, if you’re noticing the nights are getting significantly colder than in the summer and early autumn, it would be a good idea to start preparations to winterize your boat.

If you wake up to find a frost on the ground, that is a very strong indication that you need to winterize your boat as soon as possible. Don’t delay! Once you have nights where the temperature repeatedly drops below zero, you will need to winterize as soon as possible.

Similarly, if a storm is predicated, you need to take immediate action to avoid damage to your boat, including taking your boat out of the water if it isn’t already in dry storage. Regardless of your plans to winterize or not, you’d be wise to keep an eye on the forecast and get ready to act quickly if need be.

It is important to bear in mind that once you winterize your boat, you won’t be able to use it again, even if the weather becomes warmer a few weeks later. This means that you need to be certain it’s the right time before starting the process of winterizing!

The exception is if you choose to store your boat in the water, in which case you can still use it during warmer spells. However, if you are living in a place where the temperature is known to drop below freezing occasionally, you should still take some precautions. This includes winterizing systems like the water holding tank, faucets and showers if you boat has them. Don’t use them during the winter - it is a small sacrifice to avoid winterizing repeatedly.

Like with many things, the effects of climate change have made winterizing a bit less predictable. Exactly when to winterize your boat is now much more about guesswork and judging the conditions on the ground. The seasons are no longer as predictable as they were in the past and weather conditions can vary widely year on year.

In the UK, for instance, it is much harder to make a concrete prediction on how low the temperature will get and when, so it is best to exercise caution with your winterizing plans. If you hear word of a Beast from the East (as in 2018), winterize your boat without delay!

Unless you live in a hot climate year-round, it is best to winterize your boat even if it will only be out of use for a few weeks. You can winterize your boat in less than an hour and it will significantly reduce the chance that you have to cope with freeze-related damages next season.

The exact time for winterizing your boat will vary year on year and is dependent on factors including where you live, how your boat will be stored and what the weather predictions are for the arrival of winter. Knowing when to winterize your boat involves using your senses - check for signs of the temperature dropping and look out for evidence of frost or freezing. These are the strongest indications that winter is coming!

William has written a detailed step-by-step winterizing guide. Go check that out if you want to learn exactly what you need to do to keep your boat in great condition.

It is the final process in which you have to take your boat out of the ride. You should make sure that all the electronics onboard are working. You have to check the navigational lights, charge your battery, and do a quick clean-up.

This is necessary to replace periodically, and it helps run the boat smoothly. You can refill the cooling system, and the gas tank can be topped off with fresh fuel. Replace the cracks to prevent any damage.

Water begins to freeze at temperatures below 32 degrees. Suppose impurities or saltwater begins to freeze at 28 degrees. But in many cases, water will not freeze, resulting in cracked engine blocks.

There are some amazing tips on how can you de-winterize your boat;

First of all, take the trap off. It is necessary to cover your boat; otherwise, you have to clean your boat deeply and pay time and money. Due to some of the unwanted visitors in your boat, your boat will have snakes, bugs, rodents, and birds that is why it is crucial to deeply clean and have a strong protective covering for your boat.

If you have or not, the basic knowledge about the de-winterization is to check the engine's condition. Because of the storage of the boat for a long time, the engine can be damaged. You have to change the oil and outdrive before starting the engine. Make sure to add an oil filter and oil additive. It functions to protect the engine from corrosion.

The next important step is to drain the cooling system. This helps to prevent the freezing of the cooling system. Make sure to empty the filter and cooling systems hoses for holes. You can refill the system entirely.

A thermostat regulates the water and plays a vital role. If the temperature of your engine is too cold or too high, it may not work correctly. You can change it after 200 hours. Water pumps play their rules to flow the water to cool the engine. Like a thermostat, you should replace the water pump after 200 hours of use.

When you de-winterize your boat, you have to check the condition of your battery. It is an essential step, so you should check the volts and current in the battery with a tester. If it is working correctly, clean the battery terminals' corrosion. If it is not performing well, then replace it immediately.

Another critical step is to check the fuel system for de-winterizing. Before the boat's storage, you have to refill the fuel system to remain lubricant and allow no moisture to enter and damage the fuel system. Since the fuel system is made up of rubber, you have to check the cracks in the fuel lines because these are very common. You have to change your fuel filter to prevent any damage.

One-third of the boat sinks only because of the damage to the exterior of the boat. Be careful about checking the body of the boat. It can be possible that your boat has no damage before storage, but something happens, and it has some cracks. You can go to the boating expert if you need any help. So when you de-winterize your boat, make sure to check the exterior of the boat properly.

When it comes to owning a boat, de-winterizing is the process of taking your boat out of storage and assessing any maintenance needs in order to have it ready for the upcoming season. This process of de-winterization is fairly common for seasonal investments, such as your winter home or other vehicles stored away during the colder months that require special attention to prepare for use.

Jump to FAQs about boat de-winterization:

There are many steps to de-winterize a boat and the process can take quite a bit of time. Despite the time or money needed to winterize and de-winterize, boat repair expenses for serious damage make it far less costly than the alternative. Failing to winterize and de-winterize a boat every season can have catastrophic results.

Here are the key steps to follow to de-winterize a boat properly and ensure it stays sea-worthy for years to come:

It’s possible that animals or other pests got onto your boat during the winter. Covering it well with a good quality cover goes a long way to preventing this. However, they’re small and determined so no cover will be 100% effective. For added insurance, some people like to use an electronic repellent device. Be thorough but incredibly careful anytime you de-winterize a boat as some of these animals can be dangerous.

After a long winter stored away, it’s expected to find some dirt, dust, or leaves that got under the cover. Dirt and dust especially are so small that keeping them out completely is nearly impossible. Having a good shop vacuum on hand can help. Make sure to vacuum any surface that may have gotten dirty. As you clean, look for any damage that may have occurred. If any of the upholstery is damaged, patch it well.

One of the most important parts of learning how to de-winterize a boat is learning to conduct a thorough inspection and proper boat maintenance.

Use this handy boating checklist to cover all areas that need to be checked and cared for upon taking your boat out of storage:

As part of your checklist to de-winterize, boat safety should be a priority. The safety equipment you’re required to have by law depends on factors like the location and jurisdiction of your boating destination and the kind of boat you have. The Coast Guard, state and local governments, Park Services, different federal agencies, etc., each have a different set of minimum safety regulations for each boat size, age group, and activity.

You must always be aware of where you’ll be and what minimum safety requirements apply. Remember, those are minimums. It’s always better to be over-prepared than under-protected. As you de-winterize, boat safety supplies should all be checked to ensure no items are damaged or expired. Emergency flares and fire extinguishers do expire or become ineffective so keep records of when you service and replace them.

When you de-winterize, boat cleaning and polishing may seem superficial. However, proper maintenance includes washing to prevent erosion over time. Lightly power washing can loosen stubborn grime and mildew. Regular anti-fouling paint maintenance can prevent hull rot. For teak boats, apply fresh teak oil and allow it time to soak in completely.

Don’t forget to put back the personal items and boat accessories you removed before storing. Something always gets forgotten until the moment you need it most. Making a checklist of things you remove as you winterize avoids this. Then, as you de-winterize, boat accessories will be at the end of your checklist, so you won’t miss anything.

Yes! If you don’t take the time to properly de-winterize, boat damage that goes unnoticed worsens and can lead to injury.

The cost to de-winterize a boat depends on many factors. Firstly, size. The bigger the boat, the higher the price. Geography is a factor as well. The most unpredictable variable concerns issues found while de-winterizing. If it only requires basic maintenance like fluid changes, it will be much cheaper than something like the engine needing repairs from freezing damage. On average, most people only spend a few hundred dollars.

It’s not safe to de-winterize a boat until after the last frost of the season. When your area’s temperatures remain above 32 degrees consistently, you can safely de-winterize your boat.

You can’t take a winterized boat out of storage and immediately start the engine without risking serious damage. To start it safely, you must de-winterize a boat before starting the engine.

Now that you know how to de-winterize a boat, it’s important to remember the reasons to winterize and de-winterize a boat in the first place. If you don’t store your boat properly by having a cover securely in place, using indoor boat storage whenever possible, and keeping it well maintained year-round—yes, that means even in the summer it needs maintenance and storage—you’ll be in for a rude awakening.

Leaving your boat unprotected, no matter the season, often means paying for needless and expensive repairs likely to easily top the cost of a storage unit. In the summer, UV rays can damage surfaces, animals can enter more easily, humidity and salinity may harm the wood, and marine life like algae, fish, and barnacles can wreak havoc on the hull. In the winter, water expands with incredible force as it freezes. The extreme temperatures and pressure can rip holes in hoses, create rust, and even crack your engine.

The engine impeller is the rubber piece that pumps the raw water to the engine components, and is susceptible to drying out over the winter while it's not being used. That is why most inboard engine manufacturers recommend having this done in the Spring, just before you start to use the boat again.

Dewinterization is the first chance you'll get to clean and inspect your boat's engine, propeller, battery, belts, fuel lines, etc., after the months it spent in storage or outside in your backyard, braving the elements. During this process, you're able to assess any damages, maintenance, and repairs your boat needs before putting it in the water, which can save you thousands of dollars down the line if done correctly.

You may get tempted to dewinterize your boat at the first sign of warm and sunny weather, but if you live in a place like New England where you could see spring- and summer-like temperatures one day, then snow and sleet the next, it’s vital to wait until the last spring freeze. To find the latest information about frost/freeze in your area, visit the National Center for Environmental Information.

If you have no interest in doing this work yourself, you’ll receive no judgment from us. The cost to dewinterize is affordable, considering the amount of time and energy you'll save. The average price is around $300, but of course, it varies, mainly on the size of the vessel. If you have a single outboard motor, it'll be around $100. A larger cabin cruiser could cost upward of $500-$600, and possibly more.

You shouldn’t have to worry too much about this step if you were incredibly diligent in your winterization prep, but it happens to even the most prepared sailors. Smaller critters like rodents, birds, and bugs can find a way to squeeze, claw, chew, or scratch through any gaps in your canvas. So look around for droppings, nests, tears, bite marks, etc., around your boat, and be cautious when you roll back its cover.

Check the engine and propeller for dents and damages. You'll also want to change your boat's oil and the correct additives when replacing your oil filter. Oil changes will help prevent your engine from corroding or rusting over time. Fuel lines, especially, tend to crack over winter with dry cold temperatures.

Colder climates are tough on the fuel line and hoses of your boat. First, do a thorough visual inspection of the lines, cooling system hoses, and connection clips to ensure no cracked lines or loose connections. The fuel tank should have been left full through the winter with a fuel stabilizer additive so no moisture could get in your fuel tank and cause damage.

Check your fuel filter to ensure it is clean and clear. Replace it periodically to keep your boat running smoothly. Next, refill the cooling system. You can top off the tank with fresh gas if everything looks good. Finally, replace any lines or hoses with cracks that appear to be dried out and brittle.

Remove your distributor cap and ensure the distributor has not eroded over the winter. You will also want to check all your spark plugs to guarantee they’re in place and tight. You may have placed a plastic bag over your carburetor during the winterization process to keep it clean and prevent moisture from entering.

About every 200 hours of boating, the impeller’s water pump should be replaced. This part keeps water flowing down to cool your engine, so this step is one you shouldn’t ignore. If it’s ready to be replaced, then it should be.

In addition, the thermostat plays an essential role in regulating the water temperature. If it’s not working correctly, your engine can become too hot or cold. Like the water pump, make sure to replace this once it reaches 200 hours of use. Don’t forget to check your hoses for cracks or holes. If you find them, replace them immediately.

Your bilge pump includes the pump, the automatic switch, and the circuit. When water enters the bilge, it hits the switch. Therefore, if the pump doesn’t turn on appropriately, you may be in a spot of trouble.

As you've likely flushed out the cooling systems when you winterized your boat, you'll need to refill it. Even if you skipped this step last winter, you'll still want to flush and drain it, following up with replacing the antifreeze. To do so, use a diluted coolant with equal parts water (50/50 mix is standard).

As you refill your cooling systems, take a glance at the hoses to ensure no cracks or worn areas that may cause trouble later in the summer. Lastly, connect the wires of your spark plugs again.

Similar to cars, boat batteries eventually need to be replaced. The last thing you want to discover is the battery has died as your reservation ends at a marina, or worse, in the middle of the ocean.

A dead battery is easily preventable. Be sure to charge your boat's battery for a day or at least overnight before you first launch. You could also hook your boat battery to a trickle charger over the winter months.

It is of the utmost importance that you check for worn belts during the de-winterizing process to see if they need replacement. Press your hand down on them; there shouldn’t be much give. If there is a lot of slack, the belts need replacing. You should also check for soot as it is a tell-tale signal the belts need replacement.

You may need to purchase or rent a shop vacuum that you can bring on board with you to vacuum any leaves, dust, dirt, and grime that may have crept under your boat’s cover during the fall and winter. Now’s the time to clean up the cushions, vinyl, and if you're a pontoon owner, your bimini top. This is also a great time to check for and patch up any cracks or tears in the vinyl upholstery or benches.

It would be best if you repainted the bottom of your boat with anti-fouling paint to keep it clean and to avoid rot. If needed, sand and scape the bottom and wipe it down before applying paint.

Polishing or waxing your boat may seem like a vanity point in our checklist. Still, it supports the integrity of your boat's moldings. It also prevents structural damage to windshields, fiberglass, or whatever else they could be fastened against or holding together.

Use a power washer on a low setting to clean the dirt and mildew off that might have accumulated over the season, then once it's dry, go over your boat with a wax or polish. If your vessel has teak, apply a fresh oil finish and ensure it has time to absorb into the wood before putting it in the water.

Make sure all your safety equipment is not expired or damaged and ready for a potential emergency. This step is one of the most important on our list and includes reading expiration dates for fire extinguishers and replacing them if needed. You should also test the lights in the cabin and on deck, check signaling equipment like horns and flares, and check that you have the right amount of flotation devices on board.

At this point, you can reattach your elections like GPS or any navigational devices, depth finders, etc., and test lighting systems or speakers before going back out on the water.

Before getting your wakeboards, kayaks, inflatables, grills, and fishing gear onboard, ensure you have the correct amount of life jackets, fire extinguishers, First-Aid kits, and other safety equipment.

Your trailer should be kept and maintained just as well as your boat, especially if you plan on traveling long distances. First, check those tires to ensure no flats and their pressure is correct and balanced. Next, grab a friend and check the trailer's light signals as you may need to replace a bulb or two. Lastly, add lubricant where you feel it necessary.

The steering may be a bit stiff on your first spring launch. You probably won't notice this until you're already in the water, but don't panic. The most likely cause is a blockage in the steering tube. It might take some muscle to get out the hard grease that's blocking it, but once you do, you can use a steering tube brush to clean the tube. Lastly, re-grease and place the steering cable back, and then you're ready.
