I would fully winterize the engine
: flush and fill with coolant
(do not flush and leave dry), change oil
, filters, etc. etc.. Remove batteries or put them on a trickle, etc.. Clean the hull
while she is in the slings, much harder work
once the growth dries, etc..
If the boat
stays on dry and if there is a crane nearby, onecan remove the stick and give it a thorough check up.
Cover the hull
once on dry.
