    Default Bluish white Smoke at Start up. Help!!

    Suddenly my Yanmar 3GM started smoking heavily at start up only. Where as before, my engine would start without hesitation, it now takes several turns before it starts. Then bluish/white smoke billows out of the exhaust for 2 - 3 minutes and eventually clearing I also noticed a little oil sheen the water from the exhaust port. Underway there is very little smoke. After a couple hours with engine off, it starts quickly, but some more blue smoke will be apparent, but for a much shorter period. After sitting overnight, I will have the same problem. Over hall was 200 hours ago. Any help would be much appreciated.
