Buy a shop manual for your boat and then follow the winterizing instructions. You will need the manual for other service anyway.

Just google it -I found a free one online...

Those use a Force outboard power head it is self draining so you do not need to do anything except clear ALL the fuel from the carbs, actually to avoid issues with the carbs you should have a disconnect on the fuel line and run the engine on the hose after each use with the fuel disconnected so it runs out the fuel from the carbs avoiding old fuel evaporating from the bowls and gumming things up.
