I have SD20's, they should drop out down the bottom of the hull
, not up through the boat. You have to seperate the upper and lower portions of the SD to do this, lots of bolts on the upper portion going down into the lower as I remember.
Sorry I cant be of more help though, I only watched. I would call a Yanmar mechanic
and have a 10-15 minute conversation with them.
I would change both seals
(boots) on both saildrives if you have never done either SD before, otherwise its just a matter of time and another unexpected haul out
. I know there are bands (big hose clamps) that also need to be replaced, and some type of adhesive
. The thought of a mistake was a bit to risky for me so I hired someone.
, I always remove the cone and the prop (and spacer and other little parts), clean it all up, and re-grease and re-assemble. Just makes it easier later if you need to take anything apart. Check the zincs obviously. Make sure the o-ring on the oil plug
at the bottom is in good shape so that when you re-fill there is a good seal to keep water
out/oil in (I use a dab of liquid gasket
as well as its not worth the risk to me).
By the way, I hate saildrives
