I just recently purchased a 2000 mercury optimax 150hp. This is my first boat and with the winter season approaching I am wondering what I need to be prepared to do to properly take care and store my boat. I am currently living in South Carolina so it does get cold enough to freeze. So really what I am wondering is what I need to do to ensure I prevent any freezing of water in my engine. I am keeping my boat outside and want to prevent any problems. Insight would be appreciated. Thanks.
