Boat won't keep idle and dies

[Trevorg7]

So, thankfully this happened at the end of a week long trip to Tulloch but as I was pulling into the launch area and the boat died. I was running about 25mph or 2700 rpm for about 10 mins, engine was warm (normal), all other gauges and sounds were normal. I came off plane to idle speed and the boat lugged, idle dropped to <200 to where it wouldn't run and then died. I restarted in neutral and reved to about 1500 rpm and the boat was fine but once back to normal idle it died again. This happened twice and I limped into the ramp and trailer.

The boat is a 93 Ski. Carborated 351 with 384 hours.

Thoughts?

Thanks in advance. BTW, a pic from the trip for good measure! 8-)

RE: Boat won

Check the plug on the vacume port on the carb. It is on the starboard side of the carb, close to the rear. Looks like a black piece of tubing with a closed end. If it is split or has a hole in it, will cause these symptoms.

Had that happen to me on Lake Norris last month, fixed it with duct tape. You can either get another plug from an auto place or use a short piece of 3/8" fuel line with a bolt in it.
