Question
Just bought this boat and took it out today for the first time. I opened it up for about 2 minutes and it was running fine. Once it was warm it started cutting in and out and did it unless i slowed way down to near idle, i'd try to get it goin again, it would go for 10 seconds and start cuttin in and out again. Seemed like it was fine before that though. Maybe the float sticking in the carb? Also i got to lookin where the fuel connects from the tank to the motor and there's what appears to be a vacuum line missing from right beside it. I'm new to water sports but could this be the problem?

Answer
it sounds like you have a cylinder loosing fire to the plug...run it with one wire dissconnected to see if you can tell which clyinder it is....also check the plugs and make sure no water is getting on the plug.  if it is then replace the head gasket..
