I made this very basic video to show how easy it is to winterize your raw water wash-down system using a modified plunger and a piece of PVC. It's just a standard plunger and a half inch piece of PVC. This is a cheap alternative to things that are sold in many marine stores. Total with antifreeze, PVC and plunger I spent a total of $10. Much cheaper then replacing your pump. Feel free to comment and share this video to help others
