Bypass the main tank and use a small doner tank small fuel, bottle etc, be carefull as not to spill fuel. if it starts and runs on the doner tank its got to be in the pickups in the main tank. My motors vaper lock on early season fuel but it usalley happens when hot and hatch closed after running hard for 15 miles or so.... my bet it is in the pickups or water in fuel
Used a donor hose and tank to no avail... Motors would occasionally fire for a second or two and then die.
Checked for spark, and both motors had it.

But did you change your seperators first?

why is this a three page thread ? as posted above... get a small gas can, a stand alone fuel pump and a fuel pressure gage. isolate the boat fuel system completely hook up your stand alone and fire it up. either it runs properly after all the junk clears out of the injectors, or it doesn't. that tells you where to look. its not rocket science. its a small number of finite components and locations. touch them all. make sure they all work. when youre done it will run fine. you could do the whole thing on both motors in 4 hours. as opposed to shotgunning everything in some random way and never knowing anything.
the boat ran fine before. now it doesn't. its not going to be redesigning the system. its going to be something simple and easy.
think horses , not zebras

That has been known to happen.
Baddogz,
When you hooked up the spare tank, did you use any of the original fuel system? Bypass everything, and use different hoses and pump if you can. If they run then start adding things back in until they don't.

Haha, more like they pissed in my tank after a night of drinking. 
Turns out the water over the tank must have been leaking into the tank...
Siphoned 6 GALLONS (!) out of the tank yesterday, flushed the lines and then she ran like a charm. Had it out all day on Lake Elizabeth in Twin Lakes, WI. Not a big lake, but fun nonetheless!
You guys should have seen the stares. It was like we were in a Lamborghini.
The lake was pretty empty and flat, saw 69 with 8 people in the boat. LOL.
Now the next project is getting a new gasket for the fuel tank sending unit and sealing her up good.
What would you guys recommend for cleaning the clogged drain? My old man suggested 10 to 1 ratio of water to draino.

suggest you do the same , d*ck head. my first sentence says " as posted above" what he DIDN't do was isolate the system complete. the necessary FIRST step in a diagnosis that doesn't rely on voodoo and mythology.
