This motor runs well but recently I noticed some seeping out a crack in the water jacket. Its only a few drops, but what to do about it? Should I just seal it (with some of that high temp putty you can get) and hope for the best, or replace the water jacket; would I create more probloems by removing it? Can I get a replacement water jacket, or can the existing one be welded?

Clean it good and try Devcon alumumin epoxy or JB Weld

OK - thanks. Has anyone else had experience with fixing the cooling jacket this way on this particular engine, and does anyone have any servicing info as I have no documentation?
