Well after 2 months of running my boat on a rebuillt merc 2bbl carb, I am still having to fast throttle start the boat after it gets to operating temp and sits for about 15 minutes. Basically when I get to the lake, I pump the gas twice and it starts right up. But after that it only starts if I fast throttle start it. I have taken it in twice and of course it doesnt do it there on the muffs, because I dont think they are running it long enough. So i am looking for any tips that I can do because its a pain having to constantly take it in. It is a 1997 Mercruiser 5.7 in a 20 foot maxum. I appreciate all the help I have gotten on here so far.
