  • Need help to winterize my 4.3L mercruiser I/O

    I have never done this before and my manual I got with the boat is useless regarding winterization.
    What are the steps involved about draining water, adding antifreeze, running engine while adding the cylinder fogger, removing battery, etc. Thanks

    This is in a 2003 Glastron. Thanks

    Read the sticky in the i/o forum. Better get it right or you'll pay dearly come spring.
