The proper starting technique is important, I have the smaller
Mercruiser 3.0, relative new, 2006. If you follow it it starts well, if
you don't, you look silly trying to start your new boat and it doesn't
start.
So ideally, find that starting procedure... but...
If it's the carb'ed V6, the procedure is PROBABLY...
- Push in throttle-only button
- Slowly move throttle all the way wide open, then retreat to about 30%
throttle. This sets the choke.
- Start engine.
- After running a minute or so, you should be able to lower the throttle
to idle, which will click out the "throttle only" button and away you go.
If it doesn't start right away, I usually pump the throttle forward
and back quickly. But this may actually be a bad habit, although it does
seem to work eventually.
