![]() For the inboard motor winterizing recommendations scroll the page down and now we speak about how to keep an outboard motor from freezing. If you are still reading, then winter temperatures in your area get below 32F. How To Keep An Outboard Motor From Freezing No water – or antifreeze! This or the cold may get to crack a boat engine block making it unrecoverable or even sink a boat. Winterizing a boat motor is draining all water out of the system, lines and pumps included. Aye-aye, we can feel its rage when it throws a boat as a toy at sea. Reads: when water has no space to expand, it can crack metal, regardless of the metal’s strength water is stronger. The constitution of the problem is in the laws of nature again – when water freezes it adds to its volume and doing so it is unstoppable. Not only the engine is in danger but its pipes and pumps and all the way till seacocks and seals.īelow +32F is the point where the nightmare starts for freshwater, and about +27F for saltwater. ![]() Water does not freeze quickly, but you are a boater and you think wider than the actual problem. The very constitution of the problem about how cold does it have to get to crack a boat engine block as a result of exposure to freezing temperature depends on water inside the engine whether inboard or outboard. There is snow – you need antifreeze.Īpparently warming the insides of the boat or of a motor compartment may create a warm cap as soon as your heating solution can align with the outside temp of the region.Įxposure of the Motor to Low Temperatures It is a thoughtful idea to have it if winter provides some periods of cold below the motor freezing point. Below on this page we suggest directions and considerations for both cases.ĪNTIFREEZE is not a panacea but a strong solution. There is a serious difference between winterizing an inboard boat motor compared to winterizing an outboard boat motor. Thinking ahead is the safest way at sea, thinking ahead is what we do when winterizing a boat motor to keep it far from any possible freezing damage. Panic is your enemy but you prevent it wisely. Keep in mind when a frost strikes the land suddenly it shall be too late (and cold for you) to run in panic carrying marine antifreeze and an electric blanket to the boat parking. Understanding how freezing works, be sure to choose some of them. However, taking extra precautions will set your mind free.ĭepending on the region, you should choose in advance how many and which of the winterizing precautions you want to apply, and NOT necessarily all of them. Making the engine environment warmer is a good idea if a cold period strikes suddenly and/or is short enough through the year. Nothing too bad should happen from a short exposure to a freezing temperature. The boat motor freezing temperature should last a while before it causes any severe damage, because it takes a while to freeze the interiors of the boat and the insides of the motor. For other cases it is freshwater in the system. If you cruise in saltwater, cooling the engine with outboard water, the latter is naturally in the boat engine system. Start at the beginning – at what temperature will water freeze in an engine? The potential danger of freezing and of the consequent crack of the boat engine block appears at the water freezing point equal to +32F and below, as for freshwater.įor saltwater the freezing point is at about +27F providing that your engine is cooled by the outboard water.
