low oil alarm 2009 Merucry 90 hp efi

Hello all,
Running across the lake at full throttle the alarm went off for low oil. Motor went into a idle type mode "safe mode" and didn't go very fast at all. The motor is 2009 Mercury 90 hp efi on a Suntracker 21 foot pontoon boat. When I parked in boat house I could smell hot motor, after it cooled down a bit I checked oil level and it was low. Not registering on the stick. I added about 2 quarts and it was back up on the stick. Ran fine after that.
I have noticed a drop of oil coming out of the exhaust when motor is off, put kid on tube, crank motor and you can see a drop of oil come out.
Has anyone else had this problem? Is it a leak someplace or do you think the rings on the pistons are bad?
The boat stays in boat house so I wouldn't know if its leaking a little while its on the boat lift.
