I guess it's carburated? With my '83, after a week of sitting, it's a)
necessary to "pump" it once or twice to squirt some fuel into it (4 bbl
QJet) and b) necessary to leave the throttle open a bit for a minute or two
because I'm too lazy to set up the fast idle :-)
The smoke may simply be the result of the choke being on ... and maybe
that's why you need to keep the revs up a bit at first..

I have a 94' Chaparral with a 5.7 V8 Mercruiser. When starting the boat
up
on the weekend after not starting up all week i get a blue/black smoke for
about 20 seconds then it dissapates. Also when starting it for the first
time i need to pop it in neutral and rev the rpms or else it will stall.
Any suggestions? ? ? Some have said since its an older boat/engine that is
nothign to worry about. Once it's running the smoke goes away and after
running a while i can start it right up w/o reving the rpms. Any info is
appreciated
