When your ship is calling ports in the cold north it is good to feel safe that your lifeboat engine will start if need be. There are a variety of preventive measures that you can take and it all adds up to a more secure lifeboat.
Let us start with the starting battery. When a battery is fully charged and exposed to 0 deg F it has only 40 % cranking power. It is at 100% cranking power when the temperature is 80 deg F. To prevent this loss of cranking power we can install a heated box for the battery. Using a heated box we must have a thermostat to prevent over heating. We can also install battery thermal heating pad. This is a thermal pad that wraps around the battery. It is available for most sizes of batteries.
For the engine we can heat the oil pan in a similar way. There is a silicone heating pad made for this purpose and it comes with adhesive backing and can be glued to the oil pan. The availability for these heating pads is in 220v and 120v. For the oil pan size depend on the volume of your engine oil. Max watt output that I have found so far is 400W.
These two small modifications to your lifeboat will greatly improve your chances of having a trouble free voyage in the cold north.
