For any of you out there with Yanmar
SD20 Saildrives I have a quick question about the seal replacement. My manual (2013 SD20's) only talks about inspecting and replacing the rubber diaphragms (inspecting every year, replace every 5 years). While searching on Youtube I found a few videos showing how to replace the oil seals
and o rings by removing the propeller
to access the inside of the bottom of the saildrive
. I don't see anything on this in the manual. Am I just over looking it? How often should this be done? Any thoughts?
Here is the link to the Youtube video
And I've attached two snippets of the manual's instructions for the diaphragms.
Thanks in advance for your help!
