What type of tank(s) do you have?
Does the possibility exist the vent is closed or blocked? Hell add to your signature the year boat, motor and horsepower (if you got a Gayliner, we'll refer you to CTT). If it's the fuel pump you can prime it and keep pumping to make the motor run. Sounds more like a blocked line like Blue said. If you go to the trouble to unscrew the filter, replace it. Most tanks have a filter screen at the fuel fitting (exit) in the tank, one of mine was 95% clogged with debris.

Ah yes, good advice Tsub - forgot to mention the squeezing the ball test!
If it is blockage you will not be about to prime the ball at all. Mine "sucked in" or collapsed. Good luck Fish!

if the ball is empty and collapsed, the tank isn't venting, ck the vent to make sure it is clear, or your not getting gas, could be something blocking the line? clogged gas filter, something in the line, something in the pick up tube, small ball in the ck value of the gas tank, or just the ball its self??
Gas tanks are easy! just ck around you will find it!

Probably not your situation, but if you are running oil injection on an OB, make sure you are oiling. The fact that you primer ball was empty points to fuel, but they wont go far without oil either. I found out the expensive way.........

quick check list:
flat bulb = restriction before the primer bulb bulb not flat but can pump alot of fuel into motor = fuel pump not operating properly. this is the quickest and easiest way to test. go to your local sears etc buy a el cheapo vaccum/pressure guage and tie it into the line before the bulb. vaccum should not be higher then 4 inches of mercury if i remember correctly. p.s. two most common problems with fuel system check valve on fuel pick up on tank doesnt work or is stuck and fuel pump is out. hopefully you do not need to change the fuel pump.
