1995 Mercruiser 4.3 V6 problems after shut off

[markleising]

I have a 1995 Bayliner Capri 1850 with the V6 on it. When i shut the boat off, it spits and sputters for 15-30 seconds then blows up a white puff of smoke and finally dies? Bad gas? How do i fix it? Carb issues? Any help would be appreciated.
