    Is the antifreeze coming out the exhaust thru prop hub?
    The two exhaust relief holes on the transom assembly?
    Or is it coming out the inlet holes on both sides above the prop bullet?

    Either way, make sure you are getting antifreeze into the block thru the hose from the water pump.
    When I've winterized, I start by draining out the water by removing freeze plugs and opening the drain cock.
    Then I then reinstall those and undo one end of the hose I need to pour rust-inhibiting antifreeze to fill the block.
    Then I put the hose clamp back on that and pour some thru the exhaust manifolds to displace all water there and thru the oil/power steering coolers for good measure.
    I keep a bucket under the drive to collect what flows out and be sure it's antifreeze colored.

    It sounds like you put anti-freeze in the raw water cooling system. Do yourself a big favor and buy a repair manual for the drive you have, it will answer a lot of the common questions, you might have and possably enlighten you as the what type of cooling systems (yes more then one sometimes) you have on you particular configuration. In other words, it ain't a car so don't treat it like one.
