225 V-Max 3.1 OX66 EFI

I am a newbie to the yamaha world. My Questions is I read the post of people talking about changing out the 3 fuel filters on the yamaha motors and cleaning the O2 sensor. Does anybody have any pictures of where these fuel filters and O2 sensor are located at on a 225 V-Max 3.1 OX66 EFI. or any good links where I can find more info. I have been to the yamaha sight parts page but I cannot find all of the filters and the O2 Sensor. Any help would be greatly appreciated because every now and then my motor will bog down on take off. When it bogs down I put it in neutral and give it some throttle and then put it back in forward and it works just fine, any suggestions on what the problem is would also be greatly appreciated.

There is usually one filter one the motor, sometimes they have fuel water seperator on the boat. Most of the older one didn't have a water seperator. The three fuel pumps is what most people change. You got fresh plugs in it?

Yes i just put new plugs in it and it still bogs every now and then
