Winterizing your boat is just as significant as launching your boat in the spring. When winter rolls around, there are some steps you should take to winterize your boat and its engine. B.I.Q. has provided important tips to help any boat survive a long, bitter winter.

First decision  

A boaters first decision should be whether or not they are taking their boat out of the water or leaving it in. Depending on your location will determine the need to take your boat out of the water. In the south it is common for a boat to be in the water the whole year. People in locations in the upper states almost always store their boats ashore.

If you plan on storing your boat ashore it may be a safer bet for the life of the boat. Less time in the water means less deterioration and blisters on your boat’s hull. Blisters occur when water soaks into the laminate below the waterline.

If your boat has to be left in the water the thru-hulls must be protected. This can be accomplished by closing all seacocks and gate valves. If the thru-hull is left unprotected during the winter a disaster is likely. Open seacocks or gate valves left open can cause the sinking of your boat.

Fuel tank  
  • Fill your fuel tank up to capacity along with fuel stabilizer, allowing room for expansion.
  • Turn off all fuel valves and seal any through-hull exhaust ports. This is done in order to eliminate condensation, which in time will corrode your fuel tank.
  • Replace your fuel filter and water filter.

Engine Care  

When an engine isn't used for a long period of time the oil settles at the bottom of the engine, leaving the pistons and valves and other parts to the air. To protect your engine from corrosion, remove the spark plugs and spray "fogging oil" inside the carburetor and into the spark plug holes.

Replace your plugs but be sure not to reconnect the wires. This provides a coating to protect the engine parts from deterioration.

The engines old gear oil should be replaced and the lower unit gear case lubricant should be flushed and changed. Don't forget to replace your oil filter.
   
 
Antifreeze  
    You should drain your coolant (if applicable) and replace it with a non-toxic, propylene glycol based antifreeze. Ethylene glycol based antifreeze is known to release toxins into the water and boaters should try to avoid using ethylene glycol. Propylene glycol based antifreeze better for the environment and the majority of manufacturers suggest it's better for your engine.

Your battery  

If you're storing your boat outside of the water, take your battery out and store it at home to protect it from the elements of winter. Make sure your battery is fully charged and maintain this charge throughout winter to prevent freezing. Also be sure to fill and renew the water level as needed. If you plan on leaving your boat in the water it's important to leave the battery connected for the bilge pump to operate if necessary.
   
 
Clean your boat  

Before storing your boat away for the winter, you should clean your boat inside and out. You should clean dirt and barnacles because they will be more troublesome when the time comes to launch your boat in the spring. Wash, clean, and wax topsides, bottom, deck, hardware, and trim. Apply a quality Carnuba wax to all chrome and polished stainless steal pieces. Leave the wax on, unpolished until spring (this will create a protective barrier). A dehumidifier or an odor/moisture absorber can prevent mildew from forming inside of a covered boat. Clean your bilges and apply moisture displacing lubricant and some antifreeze to protect them.

Marine Head  

Turn off the thru-hull fitting on the head's intake line then run the head until all of the water has been pumped into the holding tank. Thoroughly pump the holding tank out with fresh water at least two times. After flushing the holding tank add antifreeze and pump it through the hoses, holding tank, y-valve, macerator, and the discharge hose. Be sure to use a coolant that will not damage your system.
   
 
Trailer  
    To protect your trailer's tires you should place the trailer on blocks to relieve pressure at the same time this prevents your boat from theft You can grease the bearings of the trailer and replace them if needed Check the trailers tires for wear

Cover your boat  


Whether you plan on storing your boat outside or inside a garage, you should cover your boat. Check out B.I.Q.'s parts and accessories page to find a cover to fit your boat properly. With a proper fitting boat cover it should protect it from mice, pests, bird droppings, rain, snow, and wind.

Additional Winterization tasks:  

    Clean, inspect and grease all engine control cables Check all drive belts for any signs of wear, such as riding too far down in the pulleys or any cracking Check all hoses for bulges, cracks, or limited flexibility and replace if needed Check clamps on hoses, if they are below the water line they should be double clamped Cover all engine inlets and exhausts and be sure to remove them during the spring Remove all electronics from the boat Use a moisture repelling spray on all contact points and use electrical tape to deep plugs dry
   
   
With these important steps your boat should last the winter.
