I have a 1997 4.3L Mercruiser. This past weekend I started the engine and jumped in the water to move the boat out of some shallow water. I noticed a heavy fuel smell in the exhaust. A buddy noticed the same thing which we don't notice on his boat. The idle was recently adjusted. Any thoughts or concerns with this? Engine seems to run fine/normal.

You could pull the plugs and see if you are running rich.
