Fall Lay-up
From Boat US -- I know this is more than you asked for. Hope it is useful.Inboards Change coolant--fresh-water cooled engines onlyCoolant loses its anticorrosion properties over time. Replacing it every year with a fresh 50-50 mix protects the inside of your engine.Change oil in engine and transmissionFirst take the boat out for a ride to get the oil hot and contaminants in suspension. (This also distributes the fresh coolant throughout the engine.) Replace the oil filter. Top-off fuel tanks and add biocide--diesel engines onlyKeeping the tank full inhibits condensation, a serious problem for diesel engines. Treat the fresh fuel with a biocide to retard bacteria growth. A stabilizer is unnecessary unless you expect to run the engine during the winter since the paraffin that precipitates out will be reabsorbed by the fuel when warm weather returns. Run engine out of fuel--gasoline engines onlyShut off the fuel supply and let the engine run until it stops. Fog the intake--gasoline engines onlyWhile the engine is running, remove the flame arrestor and spray fogging oil into the air intake. Give it an extra heavy shot just as the engine starves and dies. Drain fuel tank and supply lines--gasoline engines onlyAdding stabilizer is an alternative but less effective way of avoiding engine problems in the spring resulting from stale gasoline. Flush raw-water circuitIf you have a fresh-water flush connector, use it. Otherwise, close the intake seacock and disconnect the hose on the outlet side of the raw-water pump. Disconnect the cooling-water discharge hose from the exhaust manifold or riser. Run fresh water into the discharge hose to back-flush raw-water passages and rinse out salt deposits. You can extend the disconnected pump hose outside the boat or let the bilge pump handle the flush discharge. Protect raw-water passages--raw-water cooled diesel engines onlyThe raw water circuit must be drained to prevent freezing, but air exposure promotes corrosion. Reconnect the water-pump outlet hose. Insert a funnel into the disconnected discharge hose and pour a 50-50 mix of propylene glycol antifreeze into the funnel until the hose will not accept more. Allow the mixture to remain inside the block for several minutes, then open all raw-water drain plugs and drain the engine. This treatment leaves behind a layer of corrosion protection on the water-jacket, and it freeze-protects any water that might be harbored in low spots inside the engine.This treatment is also applicable to protecting the heat exchanger on a fresh-water cooled engine. Remove raw-water impellerAntifreeze swells some rubbers, so rinse the extracted impeller as a precaution. Some grease the impeller and reinstall it. My preference is to leave it out until spring so the vanes don't take a set. Fog cylinders--gasoline engines onlyRemove the spark plugs and spray fogging oil into the holes. "Bump" the starter to spread the oil on the cylinder walls. Regap or replace plugs, as required, and reinstall. Fog intake--diesel engines onlySpray fogging oil into the intake manifold and turn the engine over slowly by hand to draw the oil into the cylinders and spread it. Do not use the starter, even with the stop control pulled out; the engine can start on the fogging oil. Drain muffler canisterThe less moisture the engine is exposed to, the less corrosion will occur. Degrease, derust, touch-upMaintain all painted surfaces to keep corrosion at bay. Grease control cablesExtract control cables from their housings and coat them with grease. If you cannot remove them, tape an oil-filled bag tightly around the high end of the housing; the oil will work its way down the cable. Lubricate linkages and pivots. Coat unpainted parts with an anticorrosion spraySeal all engine and tank openingsKeep moist air from getting inside your engine and tanks. Seal air inlets, crankcase and transmission breathers, exhaust outlets, and tank vents. Fabricate caps from plastic containers and tape them in place with plastic tape to create an airtight seal. Tighten stuffing boxIf the boat will be stored in the water, tighten the stuffing box to eliminate all dripping. Tag it to remind you to loosen it in the spring. Fall Lay-upby Don CaseyNothing is harder on your boat than neglect, and neglect is exactly what recreational boats are subjected to when cold weather settles in. But proper lay-up techniques can minimize the ill effects winter disuse will have on your boat. A prime objective of lay-up is to prepare your boat for the inevitability of freezing conditions. Fluids must be removed or protected, and nothing should be aboard that might be damaged by low temperatures. Prepare a checklistThe most important tool for properly winterizing your boat is a pencil. Unless you prepare a comprehensive checklist--and follow it--chances are good that you will miss a step or two. Spending a few minutes now tailoring the generic checklist below to your specific requirements will next spring save you hours of dealing with the consequences of an oversight. Empty lockers of perishablesAlso take off any cans or bottles containing liquids that could freeze. Freezeproof the toiletEvery toilet I have ever removed has dumped water (I hope) on the cabin sole when turned sideways to pass through the head door, so pumping a toilet "dry" may prove inadequate. Disconnect the inlet hose from the closed seacock and submerge it in a 50-50 mix of water and propylene glycol antifreeze. Operate the head until you are sure the antifreeze has passed through the toilet and all lines. If you have an onboard sewage treatment system, follow the manufacturer's instructions for winterizing. NOTE: For all pump, tank, and hose winterizing, use only non-toxic propylene glycol antifreeze. Never use the ethylene glycol type--common automotive antifreeze--which is poisonous. Pump out the holding tankIf the holding tank was empty and clean when you treated the toilet, you can leave the antifreeze mix in the tank, but an empty tank is better. Empty all freshwater tanksAntifreeze is not practical because a 50-50 solution is required, and you then have to empty the tanks in the spring anyway. Remember that the pump pickup is above the bottom, so you will have to pump or sponge the tank dry through the clean-out port. This is a good time to wipe down the interior of the tank with a chlorine solution. Drain the water heaterIf your water heater has an electrical element, electrically disconnect the heater before you drain it. Because the element will burn out unless submerged, attach a tag to the electrical connection to remind you to refill the tank before restoring the connection. Drain or protect pumps and hosesEven though you are going to drain pumps and hoses, it is advisable to pump a 50-50 antifreeze solution through them to protect pockets or low spots that could be harboring residual water. If your boat is fitted with a water heater--now empty--bypass it (by disconnecting inlet and outlet hoses and connecting them together) so the antifreeze reaches the hot-water side of your plumbing. NOTE: For uncomplicated water delivery configurations, draining--without the antifreeze treatment--will be adequate as long as you make sure no water remains in pumps or low spots in hoses. Drain the accumulatorWater doesn't actually flow through your accumulator tank, so pumping antifreeze through the lines puts very little into the accumulator--like pouring more water into a full jug. If it doesn't drain when you remove the hoses, blow through the T connector, or dismount the tank and shake it empty. Protect refrigeration and air-conditioning condensersInternal loops in the water passages typically prevent complete drainage, so disconnect the raw-water connection from the closed seacock and submerge it in a 50-50 antifreeze mix. Run the system to force the antifreeze through the pump and all lines. Drain. Drain baitwell and/or washdown pumps and hosesCheck valves can prevent the lines from draining completely, so you may need to disconnect hoses at both ends. Baitwell tanks must, of course, be empty. Empty shower sumpsDon't expect the pump to leave the shower sump dry. You will need to release the sump and pour it empty or sponge the sump dry. Empty propane linesLight a burner on the galley stove--and any other gas appliances--then turn off the manual valve on the propane tank(s). When the burner(s) goes out, close it and flip the solenoid switch to off. Remove sails and canvasExposing awnings and sails to winter storms--even folded or furled--definitely shortens and too often terminates their lives. Lubricate furling systemsIf your furling system requires lubrication, this is the time to do it. Service winchesIf you do this in the fall, you will know that the internal components are well protected from corrosion for the winter, and the winches will be ready for service in the spring without further attention. Remove electronicsSpending winters in a warm, dry place prolongs the life of your electronics. Taking them off the boat also eliminates the risk of theft. Spray the open connectors with a moisture-displacing lubricant to protect the contacts from the formation of corrosion. Extract the log impeller and replace it with the plug. Protect batteriesIf wet-cell batteries are allowed to discharge the electrolyte becomes pure water, which will freeze and ruin the battery. On small boats, bring batteries to a fully charged condition, then remove them from the boat and store in a dry, cool (not frigid) location. Wash and thoroughly dry the tops of stored batteries to reduce the potential for self-discharge. Do not leave stored batteries connected to a portable charger. Unless the charger turns off completely--few do--the batteries will suffer damage. However, stored batteries should be brought to full charge once a month, so post yourself a reminder. If the batteries will be stored aboard because they are too heavy for convenient removal, they must be maintained in a full charge condition all winter. This requires a power connection and a charger with a "float" stage. Winterize the engineA helpful checklist for this essential component of fall lay-up is available as a separate Don Casey Shows You How... sheet. Scrub the exteriorFlushing salt residue from hardware and rigging reduces the potential for corrosion, and grime left on fiberglass or painted surfaces until spring will be that much harder to remove. Touch up brightworkDo not leave damaged spots bare all winter. Wax fiberglass surfacesA light coat of soft wax will protect the fiberglass from dirt and moisture. There is no need to buff it until spring Empty the bilgeBilge pumps typically fail to remove all water from the bilge. Any that remains will freeze. Pump and sponge the bilge completely dry. Open drain plugTrailerable boats should be stored with the drain plug removed and the bow elevated so precipitation that finds its way inside the boat will drain out. Sailboats are sometimes fitted with a garboard drain plug to serve the same function when wintering ashore. Remove the plug and tag it conspicuously so you cannot forget to reinstall it in the spring. Close all seacocks except cockpit drainsIf the boat is hauled, lubricate and exercise the seacocks--all of them--before closing them for the winter. Out of the water an open seacock still admits moisture, frigid air, and perhaps vermin, so close them. Vacuum, clean, and polishDirt and grease promote the growth of mold and mildew. Vacuum cushions, clean cabinet interiors, and damp-wipe all hard surfaces. Scrub the interior of refrigerators or ice chests with a mild chlorine solution. Place an open box of baking soda inside and leave the lid open or off. Prop up cushionsAir circulation to all sides of cushions is essential. Better still, remove all loose cushions from the boat entirely and store them somewhere warm and dry for the winter. This also applies to other fabric items aboard, like linens, blankets, and PFDs. Open lockers and drawers and hatchesAdequate air circulation is the best way of combating mildew. Latch-hooks can be employed to hold cabin and locker doors slightly ajar. Prop bilge access and other compartment hatches open. Hanging a mildew control bag in the cabin is a good precaution. CoverA canvas or shrink-wrap winter cover doesn't just keep precipitation out of the boat's interior, it also protects the deck. In the winter, moisture between hardware and the deck or in minute cracks in the gelcoat repeatedly freezes, jacking the cracks wider with each cycle.Covers should be padded to prevent chafe, well secured to resist buffeting, and well ventilated to allow the circulation of air beneath the tarp.
