Tom,
It sounds like a fuel related problem. We've been discussing this a lot  
lately and mostly with the 9.9 four stroke Yamaha. Most of the problems have  been 
resolved by using new gas and replacing the fuel filter on the motor. Also  
make sure your gas tank is clean and the pickup screen isn't fouled. Another  
problem is that some people do not pump the primer bulb on the fuel line long  
enough and not enough gas is reaching the fuel pump.You must pump the primer  
bulb until it becomes firm.  Also make sure the air vent on the tank is  open. 
Fresh spark plugs wouldn't hurt anything either.
One tool that I always carry on my boats is a spark tester. It fits onto  the 
spark plug and then to the plug wire and lights up if there is voltage going  
to the spark plug. They can be had on E Bay for a couple of bucks and take a 
lot  of the guess work out of engine problem diagnosing.

Hi  folks.

I hope someone out there is more knowledgeable about the Yamaha  9.9 than I
am - I haven't been able to start it for over two weeks and I've  tried every
day.  The battery is fully charged and the electric  starter cranks over but
other than a cough and a splutter for a few seconds  on the very first failed
attempt, the engine is not responding.  I'm  pretty sure the fuel line isn't
clogged.  If I flooded the engine on  the first failure, how long does it
remain  flooded?

HELP!!!!
