I have a 71 115hp Merc outboard. When at high speed and in rough water the engine cuts out. I observed fuel coming out of the jet bowl vent on the top carborator only.
Hi, Skier.<br /><br />Sounds as though the float needle is not seating properly on that top carb.<br /><br />Time for carb overhaul.<br /><br />Good luck.
What JB said... Try gently thumping the carb's bowl with the handle of a screwdriver, while someone gently squeezes the primer. Make sure the motor is level.<br />Sometimes, this is enough to un-stick a sticking float needle, and save yourself a carb rebuild. Sometimes not. Also, it could be the float has sunk, or it's tab broke-off, or bent out of adjustment -- in which case, it's time to dig-in.
