Burning Oil in 09 X-45 LY6

[CO2006X-30]

I have been noticing a decent amount of oil burn in my ly6 engine. In the last 1.5 months, I have had to add at least a quart. I take good care of my boat but use the hell out of it. There is no sign of oil leaking anywhere and I am not seeing smoke from my exhaust. Any ideas? Should I be concerned? Other than that, the boat runs and sounds GREAT.
