Winterizing a Merc 470

[spareparts]

all you have to do is treat the fuel( don't forget to run the engine long enough to allow the treated fuel to reach the carb),, fog the engine with storage oil, and drain the heat exchanger, the power steering cooler( if you have one) will drain out thru the exchanger. After youre done, lower the drive, change the gear oil, greas the gimball bearing, disconnect the battery and you bea ready till next spring
