HI,

I have a 4.3L with 210 hrs.

My son took the boat out wakeboarding yesterday and started to notice some white smoke. I went down to check the boat and it is smoking on startup from exhaust and I noticed a rainbow slick around the rear of the boat. My oil is a little low maybe 1/2-1 qt. (last oil change was about 30-40 hrs ago so not sure if that's normal to burn this much oil already on an engine with 210 hrs).

The white smoke last about 10-15 seconds. Engine sounds and seems to run fine.

Any suggestions on what to check/look for would be appreciated.

Thanks
