Yes most Matanance Manuals have a winterizing section, Winterizing your boat is really simple, Depending on your cooling system on your Boat.. Mines a Inboard V-Drive, Raw water cooled. To winterize mine i just open the Engine Block Valves Drain the water out of the Block, Use alittle compressed air to make sure the block and exhaust manifolds are clear of water, then I'll remove the inspection plate on the raw Water Pump spray a good amount of WD-40 all over and around the Impeller cover that back up, Grease all the Zert fittings ( Steering, linkages) Armor-all the interior real good, and depending on how you feel i will fill my fuel tank to the top to pervent condensation over the winter, disconnect the batteries then i cover it up wait till winters over.
Beginning of the season just close the Valves, respray the impeller , change oil and fuel filters and go play on the water
