04 OX66 rough idle - shaking

[fatboy9nc]

Hey guys,
I have a 04 ox66 3.1L Fuel Injected 200 on my skeeter i bought last year.
I've change all the fuel filters, had brucatis check the flow injectors, had the prop reworked by Mark, so everything is in great shape. I've noticed this year while I'm out there offshore graphing (mostly at idle speed) that the boat seems to be shaking/vibrating way more than last year. It's hard to see my graphs with it shaking some times. What would be some things to check to alleviate the problem?

Thanks
Scottie

You might have a float sticking causing the motor to “load” up when idling. My 03 used to do this especially when trimmed up for periods of time and would smoke more and idled rough. For me it did wonders to keep fresh plugs and do a de carb once in a while.
