searay 370 sundancer problem

Sundancer 370 exhaust and/or gas smell
Have a 1996 sundancer. Runs great. Problem is, once anchored out on the lake and/or at dock, about ten minutes post-engine turnoff, we get a faint gas smell on the starboard side of the boat. Also, separately or maybe not, if we put the A/C on in the boat, the interior gets a real exhausty gas smell. SO we leave the air off now to avoid this.
What we've tried:
1. have had professional take a look and find nothing. 2. Have had smart boarting friends take a look and find nothing. 3. have taken the various compartments apart to try and find a leak or something ourselves, have looked at the hoses and see no problem as far as we can see. 4. Have also made sure we now leave the door the the cabin closed while running, still have the problem though.

Can anyone suggest anything else?

I think I would look at the tank vent hose, & at the carb to make sure it is not dumping gas....
As far as the exhaust smell, I would contact Sea Ray & see if they had any problems with intake routing for the A/C......
Apparently it is sucking in exhaust somehow.....
It would be helpful if you would post the make/model/year of your engine & serial # if possible........
Welcome to iboats, btw.......​

"Also, separately or maybe not, if we put the A/C on in the boat, the interior gets a real exhausty gas smell. SO we leave the air off now to avoid this."

Am guessing that this boat has a generator?
And when you run it you smell gas?
Or just the starbroad motor when running you smell gas?

Need more info...........
