Hi!
Usually at the end of the season, which is soon here in the North East, I warm the boat up and go out for a few runs and then in idle it starts...chug, chug chug. I give it some gas and it goes away. Happens once in a while in recently but I notice it happening more now. Any ideas?
I changed the plugs a while back. I always put ethanol additive with the gas. I buy gas at a gas station rather than at the marina and put it in with five gallon jugs. Runs great other than that chug, chug once in a while.
