    Dang it! I thought something didnt add up right. Like I said, I don't know why the mechanic told me the middle cyclinder wasn't getting fuel to it.

    You're shop is pretty backed up with work right now, right? I'm trying to get the issue resolved by this weekend.

      Yes, we have about 30-40 boats right now divide that by average of 7 boat out a week so we are running 5-6 weeks out right now. Holly Crapp, I need to get of the computer and get my arse to work!!!!

          Swap the coil from the middle cyl. to the one that is getting fire and see if you have fire. If so you have a bad coil. If you don't get fire then a bad power pack is probable, or stator not as probable.

            Carbs were rebuilt and put back on just now. I started the motor up and pulled the middle plug wire with some insulated pliers. There was a drop in RPM which means it's firing now. Since I took off all 3 carbs do I need to test each cylinder now to make sure they're firing correctly?

              Sorry the vid is sideways.

              Tell tale stream seemed a little intermitant. Could this just be from running it on a hose? When I ran it the other day it was fine.

                Got a chance to take the boat up to Lake Conroe this weekend to run it for a while. It started up just fine every time, seemed to run alright, went about 35mph with 3 people, cooler, gear on board with a little room to go, but it kept stalling out when I let it idle for about 15-30 seconds. It would start right back up but if I didn't put it in gear it would only run a little bit and stall. I ran a 50:1 fuel mix.

                    I'm wondering why my spark plug is wet if the cylinder isn't getting fuel? Once again, the only reason I think there isn't fuel getting to it is because a mechanic told me so. I don't have a clue what method he used to come up with that. All I know is he wanted more money to look into it further.
                    get ya one of these to check for spark. cheap investment
