Someone has had to have this problem ... help Please!

Challenger Bombardier 2000 - everything runs great on this boat. Lately I have had some problems with it surging. At times it runs normal then it bogs down a little. Not enough to shut it down, it just slows it down. Before I pull it out of the water I want to know if it is something I can fix myself.

Possible bad gas?
Water in the Gas?
dirty fuel line?
Electrical?
dirty fuel filter?

Does anyone have suggestions or has had this problem before?

thanks!

mine did that last year... i pulled the fuel filter and replaced it... it was caked with crud... since then it never did it again.

thanks I will give it a try. I'm due to change the spark plugs anyway.
