yes I do pump the fuel to fill the carb bowls.. I pump it until its hard,
and then try... after it quits though typically I could pump the bulb again
as the bulb is not usually really hard anymore...

Chances are you need to rebuild the carbs. It could be the fuel pump has
dry rotted on you as well. I assume you are pumping the bubble on the
fuel line to fill the carb bowls.

Well, my old project boat's power source is an old 1972 Mercury 80hp.
I'm having a problem with it now and am really getting frustrated.

The history, this motor sat for a number of years without starting or
use. Last year I got it started a couple times briefly then it quit and I
couldn't restart it. After messing around with it this year I got
another coil, put it in, and it finally fired up. Since then I've had it
going several times, and even for durations of 10 mins in the water tank.
That was last week.

This week, I have had a harder time starting it, and when I do get it
going it doesn't seem to go for long. Actually, it'll run then die
suddenly like someone unplugged it. Twice today its been like that, and
then its a pain to get it going again. A few times it started right up
after it died, but the most recent try, it started finally, and quit 10
seconds later without any further success starting it.

What could this be?

Any ideas would be appreciated. Some of the wires on connecting to
things had been cut and fixed as they were all cracked up and corrosion
started in them.. I've unwrapped a good portion of the wires there and
spliced in good stuff to replace the really bad wires.


Thanks
Chris

Try pumping the bubble while the engine is running and see if it keeps
running as long as you keep pumping.
If so - you need a new fuel pump.
