  • Winterizing a mercruiser 3.0L engine...

    I'm looking to winterize my boat in which it received a tune up at the beginning of the summer, and any advise would be appreciated. Is this something I can easily do myself or should I take it to my local shop to have it winterized? I've already topped off the fuel and added stabilizer, but I've read that its important to fog the cylinders, drain the water completely, and change some type of lower unit oil as well. Any suggestions would be appreciated.
