Currently I have to rev the engine in order to keep it running. After 30 minutes or so of reving and extra throttle I can put keep the boat idling, but it idles at close to 2000. Can anyone give me a clue where to start? I was thinking it is possibly lossy fuel lines that suck to much air on idle but will pull more fuel when the throttle is engaged. But that is a very ignorant guess.

Thanks

How about a year or model number as there are 2 types of fuel system setups....
