So she starts great, she idles great and she'll cruise at about half throttle or slower. As soon as I go to open her up the motor starts to what I'm calling bucking and or bogging down. She hasn't stalled on me maybe only because I don't let it get to that point. Thinking it may be there vst filter or just the fuel filter. Or both. Any help and advice would be appreciated. I've personally owned the boat for 3 years and have not changed my vst or fuel filter.
 
Sounds like starvation so I would change the fuel filter and re-test. It is due for a change anyway so best to do it first up.
