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

Takes 3 things to run: air, fuel, fire. Check for spark when it does not
start. Then if good spark, that is the spark will jump a 1/2" gap with a
bright spark, then check if carb is gunked up. Try pouring a a few drops of
premis fuel down the carb and see if you get run.

I'm going to verify the sparking again...

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.

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...

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.

Get a manual for that motor, and a carb kit, rebuild the carbs. They
are simple.
