My 1990 33.5 has the 2-cylinder Yanmar. I think they upgraded in 1991 or 1992.As far as recalls, I would contact Hunter Marine by calling or sending e-mail. Does your local Hunter dealer have any data on this subject?Great boat. We have owned her for 5 years and sail all over Lake Ontario. The only thing my wife doesn't like is the high freeboard. She can't stick her hand in the passing water while sailing now. I keep telling her it's the high freeboard that helps keep us dry during bad weather.
