at WOT the motor shuts off or tries to. I see that the fuel pump has four lines. One coming from the tank, one goes to the carbs, and the other two go on the side of the block; upper and lower. The upper line is cut in half with two bolts on each end to seal it off. Why? I don't know. It idles fine just don't run at WOT. Took the bolts out and replaced with fuel line, it idled rough and sputtered. Haven't taken the boat out this way, of couse. Can anyone help me out?
