Looking for help with a situation on my Mercury 2002 4 stroke 40hp outboard. It appears that after starting and runnning the engine for several minutes. It began to stall after trying to restart with no sucess it was determined that ter was water in the tank that got fed up through the engine which caused it to stall. <br /><br />I have drined the portable tank, put fresh fule in it and changed the plugs but cannot get the engine to start or even kick. I tried spraying some carb cleaner into the carbs with no success. The primer ball seems hard but I do not think that the gas is getting to the carbs. Do not know my way around four strokes but feel that thi has to be something simple. <br /><br />Any help would be appreciated as I need to get the engine winterized and an concernec that this maty cuase additional damage if left unattended over the winter. <br /><br />Thank you all in advance.

Re: Water in Gas

Reading your post,you don't mention cleaning the carbs.Until you do,the water in them will continue to keep it from firing.As long as 1 drop of water gets on your plug,it isn't going to fire.<br /><br />Nice advantage on most 4strokes ... the carbs have a bowl drain to get rid of water.<br /><br />DHP

Di not realize their is a bowl drain can you describe where that might be on the Merc 40hp. Also how would I clean the crabs would they need to come off or can I do it still attached?

It's a bit hard to describe,and I have seen them on other engines,but not yours.The ones I have seen are usually a bronze color,located low on the carb bowls.Some even have vinyl tubes attached for easy draining.They think of everything overseas.<br /><br />DHP
