timh8000 0 Report post Posted July 20, 2009 I have a 2006 Monterey 298 ss. On the rear port side (right about where the sling sign is) there is are three stainless steel openings (top to bottom). The top opening appears to be a vent. I'm not sure what the next opening is. I was stopped by a Lake patrol that asked me to close up the vent if this is related to the sink. Can you let me know what this is? Share this post Link to post Share on other sites
