Winterizing 4 strokes

I have received a couple of pms on how I winterize my 4 stroke, so I remembered to copy my response this time. This is what I do,
Winterizing a 4 stroke is easy. I have a 00 40 Merc, and getting her ready for winter takes about 1/2 hour and about $30. My motor takes 3 quarts of oil, oil filter, and almost a quart of lower gear lube. When your ready to put it way, have the motor tilted all the way down, take the cover off of the motor, and unscrew the oil filling cap on the back of the motor. Have your oil pan in position and take off the oil plug, left side about 1/2 down the motor shaft, I think its a 9/16. Have a good number of shop rags around, it will stream out right away, then slows to a trickle and runs down the spines above the prop. Once that is drained, pull the lower and upper gear lube plugs with a big screw driver and let that drain. While all this is going on, change the oil filter, kind of a pain, but be careful not to pull or damage any wiring. Put the oil plug back in, dump in the correct number of quarts of oil. When you buy lower gear lube, also buy the pump with the screw in cap. Screw the filling cap onto the bottom gear lube hole, and pump until the gear lube comes out the top hole. Will take some time, those little pumps don’t displace much lube. Once you have lube coming out the top, put the top screw back in, unscrew the filling hose and have the bottom plug ready, this is where you have to be quick. Once you pull the filling hose off, you have to qucikly put the bottom plug in, some lube will run out, but if your quick enough, you won’t loose much.
Thats all I do. Before the last run I’ll put some stabil and sea foam in a full tank.
