carb trouble

[big muddy cruiser]

long story but hear we go. the motor is 2004 50h.p. yamaha . trouble started when fuel lines and pumpbulb deteriorated and got crap in the carbs. took them all apart and cleaned them . now themotor starts fine, idles fine, revs up with the warm up lever, when i put the boat in the water it started fine ran fine in slow speed but when i start to accelerate it falls on its face. seems like alot of fuel comes out the jets on the front of the carbs. was wondering if i replaced something wrong in the fuel enrichment ? if i accelerate real slow it will go ahead and pick up and run fine. i was looking for a good repair manual with pictures of fuelenrichment parts and sequence. any info or tips ? thanks for anything.

Go through the carbs again.
floats or needle and seats must have problems, because there should not be fuel coming out of the carbs bowl vents. That means there is too much fuel getting into carbs. and overflows.
Did you clean out or replace the fuel pump, filter, and other lines on motor.
They will hold trash and plug up carbs repeatedly if you did not.
