Hi Im a new member also a new owner of a 1994 232 w twin 150 Merc. Getting ready to launch , found two(2) drain plugs taped to steering wheel. One naturally is for the bilge drain, but the other? Im not in touch with the owner, and the winterizer (a mariner) a thousand miles from me doesnt remember. The boats scheduled launch is today at @ 2:00 Help!!
