    1997 no-spark

    Trim/tilt sending unit

    Does a 1990 90hp Mercury come with at trim/tilt sending unit. If so, where is it located? If not, can one be installed fairly easily? Just put this engine on my boat and the boat it came off of did not have a trim/tilt guage. My boat does but I had a Johnson 85 on it. Thanks,
