How to Winterize the sterdrive unit on your boat

In this tutorial, we learn how to winterize the stern drive unit on your boat. By draining the oil as the last step, you must inspect for moisture. If you have no moisture, you can assume there is no water intrusion so you don't have to do any repairs. Remove the oil out of the lower unit first, making sure to keep an eye out for metal shavings and moisture. Use the proper gear lube to make sure you are draining all the areas properly. When finished, your boat will be ready to be stored and be in working order to use next season!
