First time out for the season. The boat was running absolutely perfect for the first 2 days. I was out fishing and ran over to the dock to pick up some friends. Ran perfect. Turned it off for a few minutes and when I restarted it it would start and idle, but as soon as I put it in gear and try to throttle up, it would die. Then it got to where it didn't want to run in neutral very long without hitting the choke to keep it running. If I pump up the bulb it stays firm for a while. It doesn't seem to help if I pump it when it starts to die. Carb issue or VRO, I assume?
 
Remove plastic airbox from front of carbs. Unscrew plug on bottom of each carburetor bowl and see what comes out

I was finally able to get that done and found that I did have some water in the fuel in the float bowl. I drained the fuel tank, replaced the filter, drained the float bowls. Someone suggested that there's a drain on the VRO and that I needed to drain that, but I don't see one. Would I need to remove it and drain it out? After all of that is done, do I put a small amount of fuel in the tank and see if that has solved the problem? I've heard mixed opinions on adding a fuel treatment, too.
 
Remove the 3 carb drains.
Fresh fuel in tank & pump ball until you have clean fuel from all 3 drains.
This will flush fuel hose, ball, VRO & carbs.

How did the motor run for you last season ?----Is VRO in service ?----Oil output tested ?-----Newish water pump impeller ?

It ran fine last season, and for the first two days out this season it ran as good as it ever had. She was purring across the lake when I went to pick up some friends at the dock. I turned it off for maybe 5 min, and it started right up, but would stall every time I put it in gear. I found a little water when I drained the float bowls, so I drained the fuel tank. I took samples along the way and never found any more water, but drained it as dry as possible. I had been running regular fuel with ethanol, I won't be doing that again. I assume that caused some condensation during storage, although I did treat the fuel with SeaFoam. I'm not sure why it would have taken 2 days to have a problem, but I really wasn't running the motor much. Just to get to the area I wanted to fish and the using the trolling motor. The VRO is working fine, I can see oil in the fuel. No new water pump or impeller. I see no drain on my VRO, so I was going to add a little heat to the new fuel, try to pump whatever I can through the system to clear it. Any other suggestions?

Well, I added new fuel, a little Heet, another new filter, removed the carb drain plugs, and pumped the ball to get clean fuel. I started it and nothing is changed. I ran it for a few min by choking it when it wanted to die. It never would run on it's own for more than a few seconds. Pumping the bulb does not help, only the choke. I opened the carb drains and captured what was in there, and I see no indication of water, but I'm not sure how long it takes to separate.
 
Fuel from the electric primer valve goes directly into the intake airstream.----This fuel bypasses the carburetor metering jets.----This strongly suggests that carburetors need attention

It does seem to be pointing in that direction, although I find it odd that they would just suddenly have an issue, after everything working perfectly moments before. Since it will only stay running by pulling fuel in by tapping the choke, it obviously has some issue with fuel feeding the carbs properly. I had already made an appointment for the next opening at the shop, which is the 18th, in case I couldn't get it sorted out myself. I don't have the time or knowledge to be digging into triple carbs. Thank you for your help, I really appreciate it.

Yes, they are. I've rebuilt quite a few on small engines and cars, but I have no idea how the sync and adjust a triple setup. Honestly, I just don't have the time to do it, even if I felt comfortable that I could.
