I have a 1999 Larson SEI 186 with a 4.3gl and an sx-m sterndrive. I have some damage to my lower unit, and am in the process of removing the outrdrive. I am also preparing to winterize my boat for the first time by myself and am curious how I can give the system water with the outdrive removed? I have read some different things, but curious if anybody knows for this particular engine what would work?
