My 225 horsepower Yamaha ox66 starts up just fine but smokes more than usual at startup and at low speed idle. After getting on plane and trying to pick up speed it starts bogging down like its starving for fuel

Had the same issue on my 1998 200hp. Went through many possibilities (cleaned carbs, new crank sensor)but problem was resolved with new fuel lines.
