Now that winter is almost here and the cold is coming back, it is very advisable to preheat the engine of your boat before starting it.
As you well know, cold limits the lubricating capacity, so if the engine is revved too fast without waiting for the optimum temperature for good lubrication, we take the risk of causing more wear to the engine, which shortens its life.
For the engine preheating, the key position must be the same as the following picture.
And, furthermore, for vessels operating in extremely cold environments (water temperature between -15ºC and -1.5ºC), an engine heater and an additional air heater must be installed (inlet air heater, crankcase heater).
Enjoy your Solé Diesel engine for a long time. Do not forget to make the preheating. And keep on sailing!
