We have a mercruiser 4.3L and there seems to be a strong smell of fuel when idling. All fuel lines have been checked for leaks and are OK. The plugs have been checked and have no signs of fouling due to richness. Any ideas or is this normal
As Jerry mentions - check the oil for gas. If you have a mechanical pump, the diaphram can rupture and put gas in the oil. Otherwise.... double and triple check all the fittings - including the fill and vent lines.

Depends on how much gas may be in the oil. Smell is the first check.
If it smells like fuel check the stick to see if the level is over full.
Also there should be a small plastic hose from the pump to the carb,(usually clear or yellow plastic)Check it to see if it has traces of fuel in it.
If so the fuel pump is bad.

That hose is the vent so if it does rupture it will show in the tube.
We had a boat last year that wife keep saying she was smelling gas.
Turned out she was sitting by the tank vent fitting on the hull. If you are idling and maybe wind at the stern, this could be your problem.
