The above link may be a duplicate (sorry for a double dip) but I remembered I had it saved on my browser.
I and changing mine right now (36 degrees outside and going to be in the 20's for a good 10 to 13 hours at night for the next 4 days). The procedure seems to be working out very well for me.

Re: Very good procedure for changing lower unit lube

Just finished per this procedure on my Merc 150--worked great--this was my first time doing the lube change and it worked great--one thing though--when you back the top plug out to let the air out but careful and not unscrew it too far (keep pressure on it) or it will blow out.
Enjoy.
