Drain water side of heat exchanger and water pump as likely lowest point. Depends on exactly what closed cooling system you have
verify strength of AF on engine side is ok for lowest temps.
stabilize fuel some will run a mix of 20% 2 cycle oil and fuel to fog engine
change engine oil
change drive oil
if you have water in either look into it now not in spring
Hit your grease points, take prop(s) off and grease splines.
if you have a toilet and or water system that will need running marine rv af through
inspect bellows , might think about water pump impeller if its been a while
bestbet get factory manual fir your engine follow procedures fir winter layup
