Need help with my mercury 25xd

zseverns · Aug 1, 2012

I have a 1985 mercury 25xd that won't start I bought this motor from a shop and ran great at the shop when I got it home I started it with gas that I didn't know had water in it. After putting good new gas in it, it ran great that day. I didn't run it for about a month and now it won't start. I can get it to start by spraying gas in the carb and then it dies when the gas burns off. Do I need to get the carb rebuilt

Probably still have some water in it.Carb disassembly would be in order.

Is this an easy task I'm new to the outboard world

Usually getting the carb off is the hard part.Carbs are pretty straight forward with some mechanical knowledge.

Ok thanks I'll give it a try

Does the primer bulb pump up hard? I had issues with my 20 hp and it turned out to be the quick disconnect at the motor was sucking air. The PO had purchased a cheap off breed quick connector, I replaced it with a genuine Mercury part and my idle no start issue was gone.

Well I got it running agin just alil trash in the carb I put a fuel filter on it after I ran it the first time so hopefully that issue is over I also disconnected the gas and let it run out of gas. Is that ok to do so?

Not good.As stated in another post on a 2 stroke your oil is in the gas.Anyway you don't run all the gas out.There's always fuel left in the carb unless you drain it.
