Some use an oil pressure switch to control an electric fuel pump.

Jim, mine does the same thing, only not to that extreme. I changed out
the point set to a pertronix electronic (it DOES run better!) but a
cold start takes a bit of cranking.

I'm not sure, but does mercruiser use a low oil pressure kill switch?
so you have to have oil pressure before it wil fire?

That's what my 3.0 acts like....

Try cranking the throttle wide open once then return to neutral the crank

open just a hair. This usually works. You might need to adjust the choke
a
little. 14 pumps is probably flooding the engine.
Blow out the sterndrive petot with compressed air or a garden hose. Blow
on
the hose with your mouth and have a friend watch to see if the meter
moves.
Make sure the tubing isn't kinked or punctured.

PROBLEM 1: I have a 94 Chaparral w/ a 350MAG Mercruiser. I recently
took
the outdrive off for servicing and after replacing the speedometer
didn't
work. It is defintely connected What are the best ways to trouble
shoot
this problem out of the water?

Also I previously posted the following: -----------
REOCURRING PROBLEM 2:
I have a 94' Mercruiser V8 350 engine in my boat (21' chaparral). For
the
past year I have had some difficulty starting it. I dry dock it and
when
I
start it up on the hose in the beginning of the weekend to make sure
everything is working before taking it out, it's extremely difficult to
start, I usually have to put it in neutral and pump/push it forward and
back
maybe 5 times then almost put the throttle all the way forward for it
to
start (and still it has to crank for a about 5 seconds before it
starts),
once started i run it at maybe 2000rpm for a minute or two then I can
put
it
back to idle and no problem. If I let it run for a while the next time
i
go
to start it, it turns over perfectly.... Now when I put it in the water
an
hour or two later, i have the same problem except it is magnified and
more
difficult to start.

As for the starting problem, i have tried pumping the throttle like
10-15
times before starting, but still takes forever....


THANKS FOR ANY HELP..
