Thanks JBC I'm guilty of guesstimating on this one... I have a picture that I measured (in comparison to the background). I have the dang thing laying around, I just can't seem to locate it right now.
We got the boat out this weekend and ran it around a little bit (after doing the fuel pump rebuild) and the problem persists... My buddy believes the carbs need cleaned, perhaps some gunk in one of the jets.
Here is a video from Chatfield on Sunday afternoon. This one at least shows us up to speed, if you pay close attention you can see the engine studder when we give it the spurs.
The gentlemen in the front is my Dad, and the driver is my friend (and PO) Rick.
