I have searched as best as I could for some specific directions for a 3.0 winterization process but no luck so far. Does anybody know where I could find an OEM manual for a '92 Merc 3.0?

Thanks!:confused:

UPDATE: Well I found the manual but it has NOTHING about winterization process (location of plugs etc..)

Re: Mercruiser 3.0 Winterization

Apply muffs, flush motor, then fog thru the carb untill it stalls
remove drain plug in block and exaust manifold,(port side just above oil pan)
drain block and manifold (probe holes to verify draining)then re-install plugs.
remove large hose from therm housing and pour in A/F untill it comes out the top,re-install hose.
remove small hose from manifold, pour A/F in untill it comes out the exaust.
shift into fwd and remove outdrive,check drive oil, grease U joints, grease gimbal bearing, stick a 2 ltr sode bottle in the hole and your done.
