One of the most important steps in extending the trouble-free life of your Mercruiser engine is to be sure that it has
been properly serviced and prepared for cold weather during the winter. Water left in the engine can cause major damage to the engine block and the manifold system. Below are some things you should do each winter.
The importance of a service manual cannot be overstated. The Mercruiser's manual has a very good and detailed section on winterization procedures. We strongly recommend that your MerCruiser is winterized by an
authorized MerCruiser dealer. Damage caused by freezing or improper winterization is NOT covered by the limited factory warranty
