98 merc 4.3, stalls and wont start
The boat is running fine but I have had trouble with it stalling and then
not restarting. It only happens when cruising slowly. It will sputter for a couple of seconds then stall. The only way I have found to get it restarted is to take off the flame arrester, open the choke and move the throttle lever to full throttle. I let is sit that way for and hour and it usually starts. Any idea what could cause this? |

I'm no carb expert, but it sounds to me like the carburator is dumping
in fuel at low RPM. You said someting interesting that you had to take off the "breather" and ..."OPEN THE CHOKE...". To me that is an indicator that the choke isn't working properly. When the engine is warmed up the choke butterfly should be wide open and should stay wide open. If it's closing off at low speed then it's dumping gas into the intake thwoing your air/fuel mixture way off.
