2007 BF50 carb model. Approx 50-70 hours.
I started her up for the first time this season today and she started right up but is struggling / dying at idle and is shaking more than is typical.
Backstory --- last summer I had a water in the gas issue (seawater, rainwater, probably some of both) that caused the same issue. The Honda mechanic replaced one of the carbs, which didnt solve the problem, so I went back and he removed and thoroughly cleaned all three carbs. This solved the problem and I happily used the boat for the last month or two of summer. When I put it to bed last fall, all was well running-wise and I winterized carefully (stabilized fuel, drained carbs, changed filters, etc etc).
Now it appears to be struggling at idle again---after a while (on the muffs) it will struggle and die. I drained all the carbs, drained both inline and Racor filter, and put some seafoam in them. This temporarily solved the issue but I let it run for about 45 minutes and the problem is coming back (probably because the seafoam is burning off). Interestingly, the problem mostly goes away if I fast idle, but even at 2,000 + rpms it sounds like its skipping a bit.
Any idea whats going on? Its a fuel / carb issue, correct? I REALLY dont want to go back to the mechanic especially since it would be weeks to get in the door and I already blew through $1k last summer on this issue in parts and labor.
Thanks in advance for anything you've got!
