My 1999 Yamaha 225 HP has a problem because when it turns on that is normal but when I try to accelerate the RPM keeps going up and down I also changed the gas line and the fuel pumps but follows the same problem.

Search trouble shooting fuel system. When did this start happening? How long ago did you run the boat last?
