What year is my Mercury 25 HP ? Problems with idling

[Lance Lingscheit]

I have a Mercury 25HP tiller handle serial#0D116315. Any idea what year and model number?

The motor runs great until I want it to idle then it slowly dies unless I pull out the primer(choke) knob. It seems as though I am loosing pressure in the fuel line. If I keep the primer bulb pumped it will idle fine. Any ideas?

It is a 1992. Rebuild your fuel pump.
