I just bought this boat and had it out on the lake yesterday. It was running great until it ran out of fuel. I switched tanks and it ran like crap ever since. Both tanks had fresh fuel. It seems like it is flooding out. There is clean fuel puddling at the bottom of the air intake, and black oily looking fuel coming out of the exhaust. I took the fuel filter off and cleaned it. Any suggestions? Why would it just do it all of a sudden?

Running out and possibly the gunk and crap in the bottom of the tank got sucked up and now it's in the carbs.
Drop a float bowl and see what's in it?
The black out the exhaust is unburned gas/oil and residue from the exhaust.
Possible the floats stuck and flooding out the carb and leaking.It cleans any old oil,unburned gunk out.

Thanks jerry, i'll try that. I did un hook what seemed to be a fuel hose and then started the engine and it runs fine with thst hose unhooked, the hose came from the engine to the fuel rail on the carbs. Motor runs good now but fuel is pumping through that hose while its running. I unhooked it on the fuel rail side

Found that the diaphram gasket was cracked, waiting for the part. Wish me luck!
