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?
