It only matters the year, make, model of the engine, not the boat it is installed in. It's still a 2003 Mercruiser 4.3 whether its in a Bayliner, Searay, or Maxum.
I'd pull the freeze plugs at the end to be safe. I agree with Mike, change the drive lube during decommissioning. If there are any deck drains, then pour some propylene glycol down them too. Water can collect in the elbows or if there is a dip in the line. I'd also disconnect the bilge pump discharge hose. If there is a check valve on the discharge line, it's holding water as well.
