2000 mercury 50 4 stroke leaks gas on start up .

[Gillesvio]

Every year when we put it in the water this thing does the same thing it floods and leaks gas we unplug the feed 4-5 time let it run dry and it seems to go away . Is it the way we store it does anyone have any suggestions as to what I could do to bypass this ? Besides that the old girl has been bulletproof .
Ps we do it in the yard with the ears so we don’t get gas in the water .
I’ve not done the carbs in a long ass time that huge stack is intimidating

do you disconnect the fuel line and run the carbs empty before you put it back on the trailer?

where does the leak come from?

Run fuel out of the carburetors when boat is going to be sitting for a week or more.----An empty carburetor stays clean.

Check the carb fuel bowl fuel vent system for being plugged. It's a rubber molded manifold type contraption that terminates (as in is open to atmosphere) sort of above the steering tube on the bottom side of the cowl bottom. Insects like to nest in there.

Videz complètement les carburateurs en le faisant tourner jusqu’à l’ arrêt complet c’ est mieux pour le stockage et vider le tuyau d’ arrivée d’essence sortie réservoir ou nourrice en appuyant sur la perle
