The Crankshaft is the heart and soul of the engine and whether it is a four stroke or and two-stroke you have to keep it in a excellent condition. Make sure that is properly lubed and that there are no signs of rust or humidity deposits on the bearing surfaces. Do not feel stingy to take the engine apart and ensure that everything is fine in the beginning of the season or when the engine was filled with water. Keeping the crankshaft in an immaculate condition will save you out of trouble.
